Just replaced the intake gaskets on the 82, filled the coolant back up and got the timing set and car running again last weekend, I went out tonight and started the car and it poured what looked to be white or light grey smoke out the exhaust. It did this before I tore it apart also. The smoke will clear up after the car runs a few minutes (5 or so and it warms up some). Does this sound like a coolant issue, ( head gaskets, cracks) ? or could it just be running rich at first ( no codes being thrown)? I pulled the plugs and they're alittle fouled, will a blown gasket foul the plugs ? The oil is fresh and I haven't noticed coolant in the oil but I haven't run it long enough yet. Also, the coolant was down about a quart but I thought this could be from it working into the motor yet. Any Ideas ?
Just watch the coolant....if it continues to be used up over a week or so running then you may have a problem.
Otherwise it is quite normal for cold engines to steam and spit water until they warm right up. That's why many of us like to give our cars a good 20minute run every time we start em up, to avoid condensation buildup in the engine, oil and exhaust.
then i wonder if you might have done something wrong on the intake install. Its like antifreeze is bleeding into the intake.
I don't know if you can borrow a cooling system pressure tester.
I don't think it's anything on my intake install, it was doing it before I put a new one on. If it were antifreeze, would it continue to smoke or does it clear up after the car warms up ? Mine is clearing up after a couple of minutes.
I had a bad experience last summer with my RV. It started blowing white smoke on startup and losing coolant. I changed the intake gasket but it didn't help. After a coolant pressure check showed a slight drop in pressure overnight I decided to pull the heads. I didn't have to go far...after dropping the exhaust manifolds I noticed a definite difference in color between #2 & #4 exhaust ports. After pulling the heads, there was a definite crack in the heads between #2 & #4. Apparently the coolant was leaking into the #2 exhaust port. I certainly hope you find something else but just be prepared.
I agree with the condensation in the exhaust diagnosis, especially if it clears up after the engine runs for a few minutes. If it didn't clear up I would then be concerned.
