[s-cars] S6 Compression

Thu Sep 24 13:42:44 PDT 2009

Greetings:

Tried to find the specs on what the factory compression number's should be on the AAN engine, all 5 of my cylinders tested out ~135lbs. My car has 132k miles and bone stock. any input would be appreciated.

Hi Y'all,

I finally got to determining the compression for the AAN engine 
(RS2ed, etc).  I'm a little concerned.

Cyl #	PSI	
   1	165	
   2	150	
   3	130	
   4	150	
   5	130	

These numbers go with the engine which was producing the noises I 
reported hearing a couple of weeks ago - mild exhaust backfire on snap let-off.

What do these numbers suggest?  IOW, am I staring an engine rebuild 
in the face?

A leakdown test would help of course, but I'd be looking for an exhaust leak
if you've got a pop on decel.
Those low readings on 3 and 5 are a bit worrying, but I wouldn't rebuild
just yet. Look for exhaust leaks, and try a leakdown test. It could be that
you've got a few valves not seating well.

Subject: Re: [s-cars] Re; not the code I expected

Tom,

The CEL came on briefly a couple of hours before the first no start occurrence.  

Other than that, the car have been running relatively well, a bit smoother with the 

new injectors, and not exhibiting any characteristics that would make you think the 

pump was having problems.  It has not been driven particularly hard lately, in large 

part because the timing belt should probably be replaced by both miles and time, 

although it looks good and does not appear to be loose at all.  The only running 

issue is the one that precipitated the upgrade/replacement of the cats with a new O2 

sensor and new plugs in the Spring and the new injectors recently; that being that 

the mileage ain't what it should be. It smells rich at times.  There have been 

occasions that there is erratic ideally at a stop, making me think a vacuum leak is 

playing in all of this, but when I have started it up and want to check, it doesn't 

do it and I can't find anything...although I do not profess to be as adept at that 

with the S-car.  I'm still stuck in the urq mode...and I've forgotten most of that.

I can't see how any of this stuff would cause a no start situation, however.  Bad 

running, but not no start.  There was a second occurrence two days ago when my wife 

stopped for gas (yes, our cars get passed around relatively unimpeded) after going 

shopping.  She called my son to come help her push it to the side, but when he got 

there, it just fired up. SO it's a warm/hot situation, but it doesn't necessarily 

take too long to cool down enough.

Ben has suggested checking the timing belt alignment, which I will, although it 

would be hard to imagine it slipping with it as tight as it seems to be.  On the 

other hand, I better look a little closer...maybe it's tight because it's running on 

top of the gear teeth and not slotted in correctly.  I will probably have to take it 

to a mechanic to get the VAGCOM  to pull codes...or maybe I should just bite the 

bullet and get it for myself now.  What's the going rate and what would I need?  

Hell, I've already put so much new into this thing, what's little more? ...and it 

still needs the headlight switch replaced (got that) the bent strut tower replaced 

and the t-belt, so I'll have to keep it a couple of years anyway.

My vote is for Austin! Forced induction will definitely provide for  
quicker delivery. Let us know, I'll bet Aria is kinda excited.
