Head gasket is blown. Look to see if there is oil in the radiator overflow tank (white plastic tank between radiator and battery), or goopy, chocolate milkshake-like sludge in the engine oil.
If there are no visible signs of oil mixing with water, another possibility is the turbocharger. The unit in the XT is water cooled, and if the seals are worn out, it is possible that coolant is leaking in the exhaust housing and exiting the tailpipe as white smoke (actually steam). If this is the case, the turbocharger will require rebuilding.
Head gasket is leaking
it means you are about to put a rod into your oil pan.
Most likely you have a blown head gasket.
if a diesel blows white smoke, it is a good indication of a blown head gasket you have coolant getting into cylanders being 89 model i figure it doesnt have a turbo if a turbo is installed it can be a bad turbo
All cars blow white smoke when they are cold especially on a cold morning .Worst case scenario if it blows excessive white smoke all the time is a blown head gasket
White smoke is from burning radiator fluent.
Under the hood on the right (passenger) side on the firewall near the hood hinge. It is black with white lettering "FWD". Subaru does not recommend that you place the vehicle in FWD mode for every day driving. It is for use only as a test mode because it does change the handling characteristics of your Forester. --Ken
sounds like you need a new head gasket
White smoke coming out of a vehicle means you need to either get your oil changed or the oil you have is too small of a weight. ---------------------------------------------------------------------------------------------- If your engine is warmed up and blowing white smoke , it sounds like engine coolant is getting into an engine cylinder from a bad head gasket , or a warped or cracked head
have a mechanic check your turbo.most will tell u that a turbo blows black smoke but can aslso blow white smoke when turbo is malfunctioning
Most likely a cracked intake manifold.
It may be the pressure releif on the bottom of the compressor. I do not have a turbo either and after I reved it some I got white smoke too. (from the oil in the ac system)
