Matty Moo Posted March 22, 2010 Report Share Posted March 22, 2010 98 s70 glt, 13g. 238k Compression is about 170ish across all 5 cylinders. Engine is relatively quiet also. Lots of black smoke. LOTS of oil in the intercooler hoses. Plugs are black. Does not want to run when it warms up, will just sit and sputter. I drove it for 2 blocks and really didn't feel any boost or hear it spool up. I took the tube off and felt for some shaft play. There's definite play. Can't really say how much since I had to use my left hand to feel for it (my right is casted). A millimeter or two? I need to find somebody with a good right hand to get in there. Pulled codes. Got 7. Five were for misfires (fouled plugs), an o2 sensor, and the air pump, of course. Prior owner said it was blowing oil out of the dipstick also, probably a pcv issue, but not sure if that would tie in to the turbo being possibly trashed. Thanks guys. Spent awhile searching but didn't come up with much. Link to comment Share on other sites More sharing options...
GltGreco Posted March 22, 2010 Report Share Posted March 22, 2010 I would start with putting in new plugs and wires and distributor and rotor, that should solve ur misfires. Then do the pcv, and any other basic problems before you worry about a little bit of play in ur turbo, performance is great but make sure the car runs nice before you get to that Link to comment Share on other sites More sharing options...

GltGreco Posted March 22, 2010 Report Share Posted March 22, 2010 I know that im just saying you asked if these other issues could be signs or results or turbo problems and the best way to go around that is fix the things you know need to be ie plugs pcv etc... and see what issues are still around and work from there.

Bah Posted March 22, 2010 Report Share Posted March 22, 2010 Curious.. If the turbo was bad, when it heats up and actually starts using live data, why would anything change? or does the SAS provide enough air and when it turns off after the heatup period, you have the issue? Makes me think electrical, until the mention of shaft play.. Link to comment Share on other sites More sharing options...

Spent awhile searching but didn't come up with much. Put your hand in either the hot or cold side and turn either wheel. You should be able to turn either wheel with one finger and less then a lb of force. Its going to be rather hard to determine if the seals are gone with the turbo on the car.

I can't stick my right hand down there, since it's in a cast. I really couldn't figure much out with my left hand other than there was some play. It was too awkward stretching over from the other side of the car. I'll have somebody stick their hand down there later today. I'm also going to see if it makes any noise. I couldn't really do it last night with the family sleeping. Link to comment Share on other sites More sharing options...

I just re-did my PCV and it fixed all oil burning / spark plug fouling / oil leaking problems in one swoop. Link to comment Share on other sites More sharing options...
matt b Posted March 22, 2010 Report Share Posted March 22, 2010 No mention of the O2 sensor in other posts, I would replace that first. I just changed out my turbo, it had shaft play, nothing too drastic but the shop agreed that it was time to replace it. I never got the crazy smoke (which makes me thing your car is running pig rich, as would happen with a bad O2 sensor), never had the sputter, I just had low boost and was losing some oil. You seem dead set on having people tell you to change out your turbo Do the other stuff first, I've driven cars with blown turbos (the kind where the turbo whines so much, even passengers complain about it) and they still ran fine, they were just slower. I doubt all your issues could be tied back solely to your turbo. But if you want to replace it for peace of mind, contact Jason (Spanky), he built and sold me my current 16T and it's perfect.

rsmigel Posted March 22, 2010 Report Share Posted March 22, 2010 ... and remove and clean the PTC! Link to comment Share on other sites More sharing options...
Matty Moo Posted March 22, 2010 Author Report Share Posted March 22, 2010 PTC is clean, recent cap, rotor, wires, plugs. Dipstick is not smoking at idle and actually has negative pressure while idling. Link to comment Share on other sites More sharing options...
ozzimark Posted March 22, 2010 Report Share Posted March 22, 2010 Black smoke is fuel. Blue smoke is oil. You're running rich, it has nothing to do with the turbo. Replace the ECT and thermostat, if problems persist, O2 sensors. Link to comment Share on other sites More sharing options...
Matty Moo Posted March 22, 2010 Author Report Share Posted March 22, 2010 Just got in from replacing the plugs and front o2 sensor. No more black smoke, it's blue now and not terrible, but noticeable. No more sputtering. Right when it's about to boost, it falls flat on it's face. I could drive around no problem just putting around. It doesnt seem to be spooling at all. I'll check all the vac lines, etc. when I have time. I didn't really have any intentions of ever driving the car, but it's too pretty to tear apart, and the engine seems so quiet. We'll see. Link to comment Share on other sites More sharing options...
