1993 saab turbo CSE. limphome mode, possible head gasket leak

1993 saab turbo CSE. I have a rebuilt engine and I see what appears to be oil leaking out of the engine apparently from the gasket (very slowly but noticably fresh oil). When cold it starts fine, then I get a white smoke out the tailpipe and when I turn it off after a few miles it will revert back to a limphome mode. I drained the coolant and filled it with water to see if the smoke changes from the tailpipe ... it appeared to be less sweet smelling possibly indicating that it is the coolant getting into the oil and burning out the tailpipe? It is apparantly the head gasket, but is there any way to override the limphome mode and run the car with a bad head gasket?

I had a blow head gasket on my BMW 6 cyl. and it was blowing white smoke and losing alot of coolant. After doing alot of research I found that all the other brands like blue devil, steel seal, KW and bars all use water-glass. The only company that does NOT USE WATER-GLASS is Dura-Seal. If you have aluminum heads it's very important to use a sealer that can flex with your engine's aluminum heads. The DuraSeal actually stays flexible! So I tried it and it stopped the smoke and overheating. No more coolant loss either. It's been running fine for over a year now. I would reccomend Dura Seal head gasket sealer to everyone... Great product! Also the tech department guys really know what they are talking about...

Things can only get get worse and that means more expense. Like mine, better to do the head gasket asap while it's not too expensive or at least get the head bolt torque settings checked after the rebuild as they may need tweeking.

I had white smoke from the tail pipeand getting hot ... I had the heads done , gasket valve . and resurfising. when I got the saab back ,I drove it about 49 miles started driving slugish , bufs of black...


Sounds to me like they did a bad head job. No pun intended. lol, White smoke indicates moisture in exhaust but black smoke indicates a oil leak. I would take it back and have them check the job they did. If the car is over heating then the head gaskets are pretty much blown.

If you don't see any leaks, then your head gasket is shot. Your coolant is going out your tailpipe.

A lot of white smoke coming from tail pipe.


Sounds like the bearings in your turbo, or your return pipe for the turbo is blocked and oil is building up to the point of leaking out the bearings into the exhaust.Let me know :)
