1990 90 nonQ woes

[Ben Walker]

Here is a quick update to this madness.  I patched up the crankcase vent
hose the best I could until I can present my wallet to the local dealer (2
hours away and still waiting for cofirmation that the part is in stock).

Car runs pretty good now EXCEPT: the engine has a sound much like lifters.
Strange thing is that the noise is not in sync with the engine and seems to
turn off and on abruptly - even during highway travel.  I am at the end of
my rope and may just put the darn thing in the markeplace.  Could it be the
AC compessor or alt?  Car runs at between 3.5 and 5+ bars and 13 volts at
guage.  So I know it is producing DC and has correct oil pressure.  Remember
when I was concerned that my oil pressure was too high?

Thanks again for all the help.

Thanks in advance for te help on this one. 1990 Audi 90 5cyl. non Quattro
non tubo 10v.  I took the warnings of the improper oil filter to heart and
decided to finally switch to the Moile 1 5W30 oil and a Wix filter (with
check valve) and a new air filter.  Of course the oil and air filter went in
without too much trouble, gotta love that air filter compartment!

While in that area I decided to also try to tackle the ISV valve - or what I
thought was the ISV valve.  This is where I should start asking questions.
The valve on top of the air box is the air flow meter - does not appear to
have an electrical connection but it does accept fuel.  Moved on to a
solenoid valve located between the port and the intake. Two vacuum hoses and
a wire connector - very corroded.  No part number on it.  I decide to clean
it with carb cleaner and use a vacuum tester.  Pumped to 100 PSI lost all
pressure within 2 seconds.

The apparent part  number is 034-906-283E.

I put everything back together except the crankcase ventilation tube (it was
collapsed) and went to start the car.  It had a hard time with idle.
Concerned the fuel delivery system had lost some prime I took it out for a 2
mile hard drive.  Response was perfect on throttle, auto trans shifting
flawlessly.  Brought it back and it idled at below 1000RPM for the first
time in 2 months.  Running smooth and idled without any problems until I
shut it off and let it sit an hour -now it acts as if it is not getting fuel
at all - all cylinders are producing spark new fuel pump humming along.

Tried capping off the solenoid valve mentioned above but still no start.
Too darn cold to have these problems.  I know the problem has to be a simple
one :-P.   Thought I would throw this one out here and see if anyone had any
technical advice of if I should send this one to the Audi Gods for
resolution.
