so I went to the right side; 150, 155, 152.

Hello Maytag,

IMHO these are great news..! (way better than the original prognostic)

Your engine has pretty good and even compression (w/less than 10% difference between cylinders), I would remove the intake plenums to clean them properly and perhaps cranking it a bit more with the plugs removed to remove as much oil residue as possible, then reinstall the plugs and run it until the smoke goes away.

Did you check the vacuum to see the AOS condition? I have an extra (used) AOS in good condition removed from my 987S that you can have it if you want, shipping it should be a few bucks..

Again, these seem to be optimistic news, good luck!

That's very generous of you, Gilles! It's known to be good? I mean, not suspect in the slightest? I'd be interested, and appreciative!

Maytag, I believe that I have two AOS and one of those should be ok, but would like to know how to test them out of the car..

Hopefully someone can share some light on this (JFP perhaps?)
