yet another... "ive got white smoke" thread
car starts up then billows white smoke from the exhaust for a couple minutes, then when the car warms up a little, starts to smoke white from the engine bay in the turbo area? everything points to bad coolant seal which is definetly my guess. im curious if i should be driving the car while its in this state? am i gonna cause damage or make anything worse by driving it? i plan on rebuilding very soon. thanks for any info you can give me!

hm i see. so definetly not a good idea to drive it then. at this point since it will probably be sitting for a couple of months, should i drain the coolant? will that cause anything to rust? whats the best route to take here.

So it only smokes in the engine bay when the car is warmed up? This sounds like separate issues.
If that's the case, I'd look for an oil leak getting onto a hot component in the engine bay. Whether it's burning coolant or burning oil, you NEED to have it accurately diagnosed right away. Smoking leaks become smoking shells of a car very quickly, please don't become that statistic.
As for the smoke on warmup, it sounds like condensation. If you restart the car a few hours later, does it smoke a lot then? (Condensation vapor only happens for me if the car is dead cold, like after cooling overnight. Coolant smoke will appear within minutes or a few hourse of a shutdown, and when the coolant leak is bad, it won't start if the engine is hot).

i'll definetly check into that. i dont know if its condensation, there is alot of smoke. and it smells like coolant, not to mention the idle is pretty bad at start up. but yeah once it warmed up a little i started to get some smoke from the turbo area. probably an oil leak? i'll have to check into it more.

definetly dont plan on driving it, thanks for the tips. so driving it with bad coolant seals will result in scorched housings forcing me to replace them when i do rebuild it correct.
it wont be on the road until i discover where the engine smoke is coming from. just trying to be cautious if i do end up driving it somewhere.

You may also want to check your gasket between the turbos and engine. If it is paper and possibly blown smoke will come out there as well. You will know because the engine will be loud'r. Well that assumes you know what a good seal sounds like.

you have 2 options if you believe it is a coolant seal:
1) drain the engine of all coolant and crank the engine for no less than 30 seconds with the plugs removed and put at least 2 ounces of 2 stroke or engine oil into the plug holes, reinstall the plugs and crank the engine for 5 seconds, this will coat the internals of oil to prevent them from rusting.
2) keep driving the car if it is not overheating, running the engine on a regular basis will keep the internals fresh until it is time to rebuild.
letting water sit in the engine for prolonged periods is the worst thing you can do for it, it will rust away the irons and rotors.
