My 1996 Ford Windstar has failed aircare due to high NOx emissions.  I
have already tried the stupid tricks that BTW, DON’T WORK.  Anyway,
the mechanic told me it’s the cat converter.  He also told me it will
be $900 for me to fix it.  

His explanation was that FORD has put two cat converters into the
windstar and that the Universal cat converter cannot be installed.  He
said there was actually room for a third cat converter that he could
install and that would be $200 plus labour...seems a little fishy to
me to install a third to clean up what the two aren’t doing, but w/e.

Apparently he has cleaned up the valves (something to do with the
EGR), that the EGR itself was fine and my Ox sensors were also working
fine.  It has to be the cat converter he says.  

So now, I am a mother with 4 children 6 and under and NO VEHICLE
because I can’t pass aircare and I have a mechanic who wants to mark
up the parts my van needs.  Can someone please tell me if the
universal cat converter can actually be installed (if it can’t then
why would they make it?!?!?!).  It’s a 3.8L,  automatic transmission,
a/c 1996 Ford Windstar.

If it were me I would take the vehicle to a combatant shop, with the proper
diagnostic equipment, that can determines WHY the CAT NEEDS to be cleaning
things up.     Apparently he CAT is trying to do more than that for which it
was designed.  Obviously the fuel/air is operating outside of the design
specs, if the CAT can not clean up the exhaust.  The problem could be as
simple as a bad plug or two.

This can be a gnarly thing.... In the past, I have been called to task for
berating someones spelling. "Ahh did a guggle serch fer hedd guskett an ah
dint find nuthin".

Since then, Google has adopted some sort of "sloppy logic" and will ask if
you meant <something similar>... but that can only go so far....

So... what does this have to do with Mike? Mike is, apparently, dyslexic -
I'm told that this isn't a sin. Combatant and competent are pretty close so
we should give him the benefit.... WTF? We're all perfect?

Since you guys are so willing to bring up the subject, let's dally on some
real "faux pas" that the rest of the world gets from the dominant country.

Is it "then" or "than"... There is a real problem with using these words in
proper context... Similar in sound and spelling, they are worlds apart in
meaning. "I would rather have lunch THEN give him a blow job" is a totally
different statement from "I would rather have lunch THAN give him a blow
job".

"My car wont 'crank'". To some, this means the motor wont turn over... to
others it means the motor will turn over but it wont start... Ask what "my
motor wont crank" means and there is a chance that someone will look at you
like you have a third eye...

A lot of posts made to UseNet are made by those that would love to appear
experienced. It's a "guy" thing - we are supposed to be wise in things
mechanical. Ain't gonna happen. Most times it's easy to tell when someone is
feeding a line. Sometimes it's hard. Bottom line is "if you need help - be
up front". Don't cloud the issue with "what you THINK". Describe the concern
in detail.... try to avoid "it sounds like the <thing> is bad without any
supporting symptoms.

I wish all of you perfect people would get off your collective a.ses and
start running the world the way it should be run. Mikes spelling mistake
isn't going to be the ruin of the Earth. Dwelling on non-issues will deflect
YOUR interest away from those things you should be concerned about.

f.ck... and you guys are allowed to vote...

That one drives me absolutly nuts!!!!!  You get a call on the phone and your

nothing happens?"  Yeah, "Something happens .. the motor makes that sound."
You say, "OK, so, let me get this straight .. you turn the key and the motor
turns over but just won't start, right?"  "And not only won't it turn over,
but I hear a clicking sound sometimes."  "You mean when trying to start it?"
"No, that was when I started it up this morning in the driveway, but it quit
a few minutes later."  "So, is it still doing it?"        "No, not now,
while I'm trying to get it to turn over."

That's what catalytic converters do.

Gee, you'd think she would have mentioned the rough running symptom.
Jim Warman - 18 May 2008 19:15 GMT
As odd as it may sound, customers are, all to often, the cause of wasted
time (and therefore expense) because they tend to leave things out. (I have
no idea if they are hoping for a cheaper invoice by minimizing the concern,
but it sounds plausible). The tech can get into a diagnosis that starts with
some extreme basics only to discover that there is "something" the owner
hasn't mentioned. If we ask why they didn't say the car had done <this> or
does <that> too, the reply is usually "I didn't think it mattered". And this
happens nearly every day and even several times in one day... It isn't the
tech deciding how much a repair is going to cost, it is the car. The tech is
simply the messenger.

FWIW, an engine misfire is going to have a greater effect on HC and CO
production than it will on NOx production.

Any condition that can drive combustion temps up, will increase NOx
production. However, misfires can destroy the converter... The resulting
meltdown may or may not restrict the exhaust flow.

For the original poster... While I am not familiar with "universal" type
catalytic converters, these "fits all" devices aren't accurately sized for
any particuaar applications (neither physically nor in their ability to deal
with exhaust flow and/or byproducts). I've often seen owners treated to
added expense because the less costly alternative didn't quite make the
grade (I think you'll find that these aftermarket suppliers will only offer
a "replacement" warranty rather than a money back warranty).

BEFORE the cat is replaced, it is crucial that the EGR (exhaust gas
recirculation) system be thoroughly tested to ensure that it is functioning
as required. Depending on the engine in your Windstar, it may have a "ported
EGR" type system. These small passages can become plugged with carbon,
robbing some cylinders of EGR flow and causing higher than normal NOx
numbers. Extreme cases can result in a car that has a rough idle concern or
even a stumble on acceleration but it can often go un-noticed, as well. It
can take a fairly talented tech to accurately diagnose this system.

Every once in a while one of the spark plugs falls out and I have to
put it back in, but other than that the idle seems to be fine.  I’m
not sure what misfiring is but I assume to someone like myself it
would just run "rough".  Occasionally, it does, then I restart it
and it’s fine.

The mechanic is " aircare certified" which means he has a gas
analyzer and a relatively good record for repairs relating to aircare.
He said the EGR and system is fine, although on the invoice it says
he repaired vacume leak.  Apparently he cleaned out the "ports" that
can build up causing high NOx emissions.  The only explanation I got
was everything else works the way it’s supposed to so my cat converter
is shot.

I don’t think he’s neccesarily wrong, the head gasket went on my van
prior to me purchasing it, a new engine was put in...I’ve replaced two
transmissions...a radiator...a couple batteries, an alternator, the
berring on the front right 2 or 3 times now...

I’ve owned this car for 3-4 years.

I am frequently asked if my engine light is on, it’s not.  For the
most part the vehicle seems to run relatively smooth.  My dash lights
are out, not sure if it’s electrical or just the bulbs, and frankly I
don’t have the money for a technician to figure it out.  

I have bad luck with mechanics, they always try to scam me...it’s
really quite frusterating, I may not know about vehicles but I’m not
stupid.  I did a little checking around for parts and I can get a ford
cat converter locally for $500.  The mechanic wanted $628 for his,
tried telling me that his distributor is giving him a discount on this
price...which is BS because I called the same person he did and
without a discount on the part is $500 and some change.

If it will help...here are the numbers.  I did two tests...

Day 1:

HC (g/km), max allowed 0.5000, vehicle reading 0.3193, avg pass 0.0873

CO (g/km), max allowed 8.0800, vehicle reading 2.8459, avg pass 1.9758

NOx (g/km) Max allowed 1.1200, vehicle reading 1.4698, avg pass 0.6229

I was advised to put fuel injecrot cleaner into my tank and premium
fuel, then drive to heat up the cat...drove for over an hour

Day 2:

HC  (g/km), Max allowed 0.5000, vehicle reading 0.2357, avg pass
0.0873

CO (g/km), Max allowed 8.0800, vehicle reading 2.3989, avg pass 1.9758

NOx (g/km), Max allowed 1.1200, vehicle reading 1.6969, avg pass
0.622

He shouldn't be guessing in that he can measure the NOx -before- the cat
and compare the readings to the post cat sample to determine whether the
reducing bed is working as it should.

Neither price sound legitimate.
My parts look up lists Ford part number F68Z-5F250-AAD catalytic
converter assembly with a list price of $1447.80

Looks to have control of fuel, HC isn't high so there's probably no
misfire.

Sounds like you have a reasonable and acceptable diagnosis.  You are under
no obligation to have that shop complete the repair.  You should pay him for
the labor and diagnostic services he as already rendered and go out to the
yellow pages and call about 5 smog and or muffler repair shops.  Ask them if
the description of the problem and other shop's solution sounds reasonable
(i.e how its better to add a third than replace the original) and of course,
how much would they charge to fix it.  Compare those quotes to your original
shop and give it to the one you can trust and afford it may be the original
shop.  If the diagnosis is correct, anyone can finish the job.

Your mechanic's shop labor rate and markup are what they are and he uses
those guidelines to quote his repair.  His quote is not BS, he may have more
overhard to support, give a better warranty, use new parts etc that may
justify a higher price.  If he choses to give a discount on labor, that
would be nice but he is not obligated. Just look for another shop to do the
repair but few places will let you give them parts to put in.  For example,
if you come in with a cat converter (of whatever source) and insist they
install it and then later you still fail smog check (that's what we call
aircare in CA) then you may not want to pay him but you should.  You may
claim that it was a wrong diagnosis and the only way to prove it would be to
replace the cat again with a reliable source, an obvoiusly inefficient and
painful course.

Frankly, it sounds like you need a new vehicle but I understand economics
may not allow that.  It may be that two or more things have failed based on
the repair history.  A new engine throws a lot of variables into why the CAT
failed in the first place.

It's pretty simple to check if a ported egr system is clogged, just actuate
the EGR valve at idle, if the engine does not change speed and the valve is
good,
the ports are plugged.  What requires a talented tech is when the ports are
NOT plugged, and the valve IS good, and there are no vacuum leaks and
the EGR valve is still not actuating.

Unfortunately, the real problem here is that in so many of these smog check
things, a lot of mekaniks* have discovered if you slap a new, universal
cat in there, it's typically a NOX and HC reducing cat - and it will get
them past the smog check - then 6 months later when the universal is
burned out because the underlying problem with the engine was never
corrected, if the customer comes back the mekanik* just replaces the
universal with straight pipe and gets his $100 from the catcon recycling
people.  Then they are good for another 2 years until the next smog check,
and by then since the engine was never fixed properly, it's likely died and
the car is in a wrecking yard.

The OP didn't say the mileage on this van but it's probably not been
maintained,
and the rings are worn and the thing is burning oil.  The car probably also
has high HC's which they are masking with the usual trick of throwing
a couple cans of drygas into the tank.  The mekanik* is probably figuring
the van is about at the end of it's life and will go any day.

So monkfish;  what makes you an authority on cat converters? It's
clear you do not know what is going on. If something simple like a bad
plug or two was the problem, I' sure the technician diagnosing the
problem would notice. See a bad plug or two is manifest with what is
called an engine miss, which the average driver would say it runs
rough. The technician would then be going down a different diagnostic
path.

Why aren't you asking stupid questions that have no meaning like you
do in other groups groups?

I assume you mean COMPETENT shop.
I suspect the one she is using IS competent, and the reduction bed of
the factory cat is dead. Adding a reduction bed cat would likely solve
the problem, for now - but it really should have the "3 way" catalyst
replaced. The reduction cat will not work properly if too far from the
manifold as it needs to run hot, The oxydation bed of the 3 way cat
makes sure the reduction bed runs hot enough to function.

Well, I'm a mechanic.
If the EGR is working right, the HC and CO are in range, and the
engine is not running hot, with no CEL lit, the only thing left is the
cat. And they DO wear out over time.
It IS possible, with a gas analyzer, to check the NOX pre-cat and
post-cat and see what the cat is doing, if anything. Looking at the
numbers, I'd say there is a good chance the oxidation catalyst is
getting a bit weak too - I'm suspicious the vehicle has been badly
neglected, and the WinStar was no gem right from new - but a new
converter will, in all likelihood, get the vehicle to pass NOW, and if
nothing else happens, likely still produce a pass in 2 years. She says
it has a "new" engine in it.
We don't know if it was "new", "rebuilt", "reconditioned", or just
"different"
We don't know if it is a 3.0 or a 3.8.
3.8 engines dropped like flies - 3.0 engines were pretty decent.

When I said new engine, I meant brand new out of the box, it’s a 3.8L
as per my original post.  

I don’t know what you mean about badly neglected...is there something
I’m supposed to do other than the regular oil changes?

The engine was replaced when I bought the vehicle, they were trying to
sell it with a blown head gasket, since I wasn’t about to buy it that
way, they put in a brand new engine.  The transmission they put in was
used.  

The first time I took it to aircare I passed just fine.  It’s been two
years and now I am failing.  Unfortunately I can’t just buy a new
vehicle...or I would have, a long time ago.

For the person who posted about me giving bogus prices...Ford charges
about $1400 for the part AND the labour to install it.  The part
itself is a little over $500.  I called them already, they were like,
my first call when I found out.  My local parts distributor (lordco)
was my second.  

Someone asked what "tricks" I used.  Fuel injector cleaner, premium
fuel and driving for a while first before going in.  The next set of
suggestions got outrageous, like, put ice in the air box...I didn’t
even bother.  

The mechanic cleaned out the ports or w/e they are called...the lines
that can get carbon build up and cause high readings...he drove it and
it still failed (although I think he just used his gas analyzer
instead of taking it through aircare).

The numbers are posted in a previous post..

Put in the new catalitic converter and you should be good to go then.
And watch the coolant like a hawk, because coolant leaks are a common
problem on 3.8s, and they are usually "fatal" Head gaskets, intake
manifolds and front covers have a tendancy to leak on them.

Even "IF" the cat were the problem, adding a third to supplement the two
worn out cats isn't a good idea. An old cat can be rotten and crusting up
inside. The small bits and pieces can plug up the new one if it is mounted
downstream. Also, depending on the smog check tech that you get, you might
be gigged for having three instead of two. He is supposed to look under
there and check for things like that.

As Jim said,"BEFORE the cat is replaced, it is crucial that the EGR (exhaust
gas
recirculation) system be thoroughly tested to ensure that it is functioning
as required." The EGR replaces air to the intake of the engine by
substituting exhaust gas that is low in oxygen. This keeps the combustion
temperature down, which lessens the creation of NOx. Better to pay to have
it checked out at a place that deals only with smog issues. You might get
lucky and have two cats that are purring fine and only have a small problem
with the EGR system.

Check out the prices for your cats here. The whole double assembly is way
under $400 with tax and shipping included, and the universal is one hell of
a lot less than the $200 that he wants for it. I have ordered from these
people a couple of times and have never had a problem. You can also google
around for a discount code. The last time I did that, I got an extra 5% off.
Good luck

It very well could be the front O2 sensor(s). Even if it looks ok on the
scanner. If he can garrantee it will pass with a third CAT that seems to be
a cheap fix. I have never heard of doing that. You might ask the smog place
about that one....Oh, and a universal type CAT around here is about $130
installed. $200 plus labor sounds way high. You might ask him about the CAT
getting hot enough to work when its install a little farther back than
normal too. Like I said, thats a new one to me.......Can you post the
readings? like HC, CO, NOx, O2........we might be able to tell whats
up....p.s. what tricks did you try? Just curious..:)

The OP did post that data on 5/18.

......................................................................
If it will help...here are the numbers.  I did two tests...

Day 1:

HC (g/km), max allowed 0.5000, vehicle reading 0.3193, avg pass 0.0873

CO (g/km), max allowed 8.0800, vehicle reading 2.8459, avg pass 1.9758

NOx (g/km) Max allowed 1.1200, vehicle reading 1.4698, avg pass 0.6229

I was advised to put fuel injecrot cleaner into my tank and premium
fuel, then drive to heat up the cat...drove for over an hour

Day 2:

HC  (g/km), Max allowed 0.5000, vehicle reading 0.2357, avg pass
0.0873

CO (g/km), Max allowed 8.0800, vehicle reading 2.3989, avg pass 1.9758

NOx (g/km), Max allowed 1.1200, vehicle reading 1.6969, avg pass
0.6229

What about that 3rd CAT trick?  ANYONE ever heard of doing that and is it
legal?
I'm curious as hell bout that one...

p.s.   for the record I would through an O2 at it in a heartbeat first.

I've heard of it, and it is legal. So is putting a cat on a vehicle
that never had one.

How can you say it's legal when you don't even know where the OP lives?   Or
did I miss that?     Where does she live?     Please excuse me if I missed
that.

Well, here in Ontario it is legal. And we have mandatory biannual
emmission tests. It is illegal to remove any emmission device. It is
technically illegal to modify an emission device. There is nothing on
the books saying you cannot ADD an emmission control device.You can
use aftermarket (universal fit) cats here too - although my luck with
them has not been terribly good.
Anything that makes it pass is fair game - but I'd be replacing the
original if at all possible.
