Oil problem was leaving for California to Tuscon Arizona in too much of
a hurry and not checking oil level before I left. Oil lite came on 50
miles before Gila Bend and - with no towns inbetween - I decided to go
for it. The cam snapped about 15 miles down the road.Total stupidity on
my part. Sad part is the engine was running just perfect before my
screwup.
I have checked the cam timing on 5 separate occasions - I am confident
the timing is set correctly, but there is still a good chance there is
a difference between the 87 D15A2 camshaft and previous years EW1
camshaft timing - even though they are both for manual transaxles. That
is what I was hoping to find out. Depending on what source you use, I
have found varying degree's of conflicting information. I am finding it
very difficult to find a source I can depend upon. The Haynes and
Chiltons manuals are an absolute joke. Mis-information in both manuals
seem to have no end. All they are good for is kindling for the fire
place in my opinion.
Unfortunately, in Tuscon the Honda's are picked pretty clean.
One would think the heads would be the same if they slip over the studs
and everything bolts on ok. But consider this - the block has the head
locating pins on the two INSIDE holes, but the head has them on the far
OUTSIDE two holes! Since there are 3 studs in place of head bolts on
the block, I figured the locating pins were not that necessary. Its
just another ??? that makes me wonder how much else is different
between EW1 and D15A2.

all symptoms are classic cam timing is not set correctly.  besides, if
this was the wrong head, it wouldn't go on at all.

additionally, if the previous cam ruined because of low oil, be prepared
for the block to be shot too.  and you want to track down the reason why
the oil disappeared.  next time, replace the whole motor.  junkers are
cheap enough and will save you a /lot/ of messing about.

Hi All-

I have an 87 Honda civic 4 door sedan 5-speed that has been sitting at
my brothers place for at least 6 years now. It broke the camshaft due
to low oil (completely my fault) and wasted the camshaft journals in
the head. I bought an 87 head from a junk yard - D15A2 - and had a
valve job done on it. I was in the process of re-installing the head
this week when I noticed something I was not aware of. I was checking
the engine block ID and noticed it is an EW1 block - NOT a D15A2 which
shows on the engine tag just above and to the left of the radiator. It
seems someone had replace the original engine with an older EW1 engine
before I bought the car. I have finished installing the head and
connected Intake and exhaust manifolds, and all other devices needed.
It starts right up and revs to approx 2500 RPM then immediately shuts
down. If you "feather" the gas it will stay running (although very
rough), and immediately dies if you let off the gas. I also get an
occasional backfire.

I have checked all vaccum hoses and lines 3 or 4 times. I have blocked
off all of the main manifold ports to eliminate manifold vacuum leaks.
I have made sure the valves are adjusted correctly and that the
camshaft pulley marks are where they should be at TDC. I just cant seem
to pinpoint the problem.

I am now wondering if there is a difference in the heads between a EW1
and D15A2 engine that would explain my problem. I bought the D15A2 head
and camshaft from an 87 manual transmission Civic - could there be a
difference in camshaft specs between an EW1 and D15A2 engine. I am not
sure what year the EW1 engine is from but I have the serial number in
case there is a way to cross reference engine numbers to years.

Any ideas?

Tom
