Does my 85 Coupe GT KX engine have a PCV valve?

[Chris Hall]

Since my car still occasionally studders / backfires (when the
studdering gets -real- bad) / stalls then takes 5-10 minutes of me
playing with vacuum hoses under the hood before it starts back up like
nothing's wrong (so I can drive right back home with my fingers
crossed), I spent an hour going through all of my vacuum hoses today
searching for a vacuum leak / broken hose, and I didn't really find
much.

I do have a question about one of the parts I inspected though:  That
little molded hard plastic "pipe" (part number 035 103 245 D) that
connects between the "valve housing" (part number 034 103 247 B... the
4 way hose on top of the valve cover that has the ring on it to hold
the ISV) to the 4 way hose that always collapses on Audis (part number
034 133 997) and all I could see was a -tiny- little hole about the
size of a ball point pen tip down where there's the 90° bend in it. 
Doing a search for the part number "035 103 245" on Google, I see
people on VW forums calling it a PCV valve.  Is that the case?  The
inside doesn't look like a "valve" to me since all I see is a tiny
little restrictive hole.  Could this little hole be the cause of all
my problems?  I know bad PCV valves can cause poor engine performance
and rough idle and even stalling... but like I said, this sure doesn't
look like a "valve" to me.

A little more info:    All of the vacuum hoses had a light coating of
oil in them, and the air measuring plate that's connected to the fuel
distributor also has some spattering of oil around the "bowl".  I know
these are typically signs of a clogged PCV valve, but I thought I've
read here in the list that these cars don't have one.

Also, there is seepage around the valve cover gasket.  I know that is
also another sign of a clogged PCV valve.  I also suspect THIS might
be where I am getting the vacuum LEAK, because when I rev the engine
with my head under the hood, I swear I can hear a light sucking sound
right before the engine comes all the way back down to idle... and the
sound is coming from the rear of the engine, near the battery... and
there's a lot of oily / greasy grime back there.

As I've mentioned before, one day last summer when I was having the
stumbling / stalling problem, I pulled the car over, popped the hood,
thought I heard the sucking sound coming from that metal vacuum pipe
that goes from the 4 way hose on top of the valve cover down to the
crankcase, so I pushed it in to that 4 way hose as deep as I could get
it to go, and I drove the car for MONTHS without ever having a stall
or studder once.  I recently clamped that connection with a hose clamp
(can't believe the metal and plastic to rubber hose connections are
just "snap together"!) after the car stalled on me again, so I think
I've eliminated any possibility of that being the source of the
leak... yet I had the car stall after throwing that clamp on that
connection.  I guess maybe it could have slipped... looking at that
connection today, the metal pipe looked kinda skewed at an angle so I
adjusted it.  I quit driving the car the same day I installed that
clamp, because it ran fine then all the sudden started to backfire
then stalled again.  Got it going again by tugging on the vac hoses,
etc and got back home.  Today after I put all of the hoses back on the
car, I started it up and it fan for 10 minutes with no problem.  Then
again, it always runs fine for a while until it starts to act up. 
Runs fine again after I play with the hoses too  haha.

Maybe the leaky valve cover gasket starts to become more of a vacuum
leak when the engine gets hot and things start expanding, and all my
playing around with the hoses is doing is letting the engine cool a
bit for that gasket leak to close up enough for the car to start, and
make the drive home with no problem????

Sorry for the short story... just trying to provide you with as much
info as I can  :)

BTW I still plan on replacing all of the vacuum hoses very soon.
