I have a 2001 GMC Duramax truck that had the injectors fail and fill
the motor with deisel fuel to the point where it was blowing out of the
fill tube. The truck only has 80,000 miles on it. There is a GM service
bulliten that was issued that says they have extended the warranty on
the injectors to 200,000 miles and 10 years so the local dealer
replaced them under warranty. I told them at that time I didn't think
that running deisel fuel inside that motor had done it any good and
that the whole motor was suspect in my opinion and was told that
"deisel contains some oil so it won't damage anything". I got a whole
2144 miles before a bearing spun and now my motor is trashed and they
are telling me that the area rep is denying my warranty coverage
because the truck is out of the official 100,000 mile 5 year warranty
by 9 months, even though the faulty injectors that caused the failure
are warranteed for 200,000 miles or 10 years . My point is that the
injector failure flooded the engine with solvent, basically, and washed
all oil away from the contact areas which caused the failure and the
mechanic who is working on it at the local dealership agrees with me
completely. I'm looking at $15,600 to get it replaced. I was hoping for
some expert opinions on the lubricating properties of deisel fuel as an
oil substitute. I'm no expert but I suspect that deisel is not really
acceptable as an engine lubricant, and I suspect that the oil pump
would not pump it as the viscosity is so low. Any
help/tips/advice/pointers towards anything printed that says DO NOT ADD
DEISEL FUEL TO YOUR ENGINE, IT WILL DAMAGE IT would be greatly
appreciated as the motor is torn apart as I type this and they are
awaiting the new engine.

P.S. I've been calling deisel mechanics all morning and I have gotten
100% confirmation that running your motor with deisel fuel in side of
it washes the oil from the contact surfaces of the motor, no ifs ands
or buts abou tit

P.P.S. DURAMAX FUEL INJECTORS CAUSE ENGINE FAILURE UPDATE: Well, I just
got off the phone with the GM Customer service people. They say that
since the 100,000 mile 5 year warranty is expired by 9 months they will
not warranty the motor even though it was RUINED by an injector failing
and flooding the engine with deisel. The injectors are warranteed for
200,000 miles or 10 years because they are DEFECTIVE ( see
http://www.thedieselpage.com/duramax/lb7injectorwarranty.htm ) and are
going bad on a regular basis according to the local dealers duramax
mechanic. I  talked to this mechanic at length who took the engine out
and HE AGREES WITH ME 100%. The mechanic told me that he has seen a
bunch of these injector failures and every time an engine gets filled
with deisel the trusks start coming in with low oil pressure readings
and "it's only a matter of time before they FAIL". He has told me that

That's right folks, A GM TRAINED DURAMAX MECHANIC HAS TOLD ME THAT HE
SEES THESE FAILURES ON A REGULAR BASIS AND THAT HE HAS TOLD THE AREA GM
REP THAT THE ENGINES ARE FAILING AS A RESULT OF THE INJECTOR PROBLEM
AND THAT GM IS REFUSING TO WARRANTY THE FAILED ENGINES.

Let me re-state the facts here: my truck is a 2001 GMC 3500 with 80,000
miles on it that only made it 2,144 miles AFTER THE ENGINE WAS FLOODED
WITH FUEL THAT WASHED AWAY THE LUBRICANT before FAILING as a result of
OIL BEING WASHED AWAY FROM THE BEARINGS. GM is refusing to honor the
warranty on grounds that in their opinion THE OIL PUMP FAILED AT 80,000
MILES which is unrelated to the flooding problem.

If they are right, THAT'S EVEN WORSE NEWS FOR DURAMAX OWNERS. YOUR OIL
PUMP COULD FAIL AT RANDOM AT 80,000 MILES AND GM WILL NOT STAND BEHIND
IT.

I suspect that eventually there will be a class action lawsuit that
will force them to pay up on these failures but right now I'm SCREWED.
I have a wife and 2 kids and make my living with the truck and now I'm
looking at $15,600 for a replacement engine from GM that I'll have to
throw on high interest credit cards if I want to be able to provide for
my family. They have me by the b@lls here. I still owe $10K on the
truck and now I'm looking at buying it again, basically, and I'm sick
inside over it.

Any helpful hints on how to proceed or any other forums you could
suggest to post to will be appreciated, as well as any help in
spreading the word. My only hope at this point is to somehow generate
enough publicity that they agree to fix it.

Thanks in advance for your help/time.
