Good day all and thanks for reading my thread.

I am doing an overhaul to this 9-5 with 140,000 on her that my friend gave me because he couldn't get her to stop smoking. Turned out a bad BOV was...

So the front corner of my headlamp assembly (not the main headlight but the light right next to it) got bumped sometime and I am trying to replace it. I am wondering if it is the same headlamp...

I use 0w40, Mobil 1. I keep my oil clean and use the K&M filter. What do you think is going on in the sump?

This is exactly what I was thinking. Started it with no spark plugs? I want a car that can do that!

I realize this is an incredibly old thread, but I just have to say something here. Most of...

Quick update. Blow off valve was only opening partially, just enough to relieve pressure into vacuum line but not enough to allow the flow of air between the two main ports. (ouch) Hopefully the...

Oh, by the way, in case anyone else was wondering, there were three ports on the throttle body, I put the other end of the small hose into the bottom port on the throttle body.

Okay, so it stopped smoking. The check valve that was covered in the insulation was completely plugged, I replaced it. Also, at the same time, I took the small line with the check valve leading...

I read a couple other responses to my issue, indicating that I could have a blown turbo. They say that I wouldn't really see oil in my cobra pipe since the oil goes to the intercooler after it blows...

Here is the small hose...where does it go? Everything just says Throttle Body, but which port?15927

Okay, so I found an issue. There is a small hose coming from the valve cover that has a check valve that was routed to what I thought was a nipple, but turned out to be a mounting post. Oops. ...

No oil seepage around the outside of the head gasket. Now I'm thinking the issue may very well be a faulty check valve in the PCV system. I would think too much crank case pressure would just blow...

I already pulled all the spark plugs out...it's pretty dirty in there. Darkish/sludge ish. Not sure what you mean about the turbo, didn't you say if the cobra pipe was clean and no oily residue...

So what generation PCV system would you recommend I get? Rings are definitely good, got 190 PSI in all cylinders. Cobra pipe is good and clean, doesn't that mean my turbo is not the problem? Any...

Okay, so I spent the majority of Saturday diagnosing my 2002 Saab 9-5 Aero. I took the cobra pipe off and it was clean. Clean pipe, and clean behind the butterfly. So then I was thinking PCV...

Well, I just got home from work, it's dark, and I have no garage. I will check my cobra pipe tomorrow afternoon.

All 4 platinum plugs do have whitish deposits. Yes I am still blowing smoke, seems like when I first start accelerating but I only drove it for 30 minutes after I re torqued the head bolts. What...

I don't think the remaining smoke is residual smoke for two reasons. (1) After torquing I drove it for about 30 minutes, I don't see how any moisture could survive in an exhaust environment for that...

Thanks for the really good information southsaab. No soot color on plugs, all have slight off white hazy texture, so valve seals probably good. Smoke is not black so I guess I'm not running too...

Hello, and thanks in advance. I've got a thick cloud of lingering white/gray smoke coming out of my exhaust. Does not smell like oil, am not losing coolant. Smells to me like car running very VERY...
