Well I checked the compression . 1) 150psi 2) 120 psi 3) 120 psi 4) 150 psi , I took the car for a drive today It seems to run great , but after driving for say 10 min. when I stop at a stop sign it seems to Idle rough, and act like its runng hot but the guage said different in the normal range, have a little pinging or knocking sound at take from stop sign and the smoke is not as bad as when it is cold. Got on the freeway and the car runs danm good

 

See if it keeps getting better. It might still be burning the oil out of the exhaust system.

Also look and see how dirty the throttle body is.

Has anyone messed with the throttle body before?

 

The throttle body is fairly clean, as far as someone mess with it I'm not sure, the car had these problem when I purchased it for a whooping $100.00 bill, you think I should check the valve clearance if so what should it be?

 

First check the throttle switch for the Idling problem. Turn the car off. Then open the hood and get close to the throttle body. Listen closely with you ear and open the throttle slowly. Listen for a click just above closed position. It should click just above closed/idle. If it doesn't then the idle motor might not be working at idle.

 

Hey forgot to tighen the distributor car now idles ok still hqave smoke, However someone told me that it could be the turbo, and before I purchased this car the other owner though itwas the turbo and replaced it ( remember the the probelm started with lack of power with the smoke) i GOING TO PUT THE OLD TURBO BACK ON THE CAR AND SEE WHAT HAPPEN.

 

Replaced the turbo I have less smoke, car seems to run better, however after about ten or fifteen miles it seems to start knocking. should I be looking for a new engine or have this one rebuilded?

 

Is it running hot?

 

hey joseph...It might be a good idea to check the timing on the belt, cam could be a tooth off.
I,ve seen it before on my 940... all the simptoms that you have described were apparent on mine.

Its easy to do and it could possibly save a lot of time and money...

not hot on the gauge, the needle seem to stay in the middle. how ever it runs like its getting hot

 

Thanks jfunez

I'll check the timing again .do the timing mark for the oil pump have to be right on the mark ? or do it matter when the distirbutor is on the rear of the head.

 

It is better to have it lined up. The shaft from the pulley in is also a counter balance shaft.
