Q: I have white milk coming out of my exhaust pipe but I don't see it mixing in my oil pan when I check my oil

asked by on

I just had my transmission rebuilt car been sitting up for about 9 months just put the transmission back in and now I have a white milky looking old and white smoke coming out my exhaust pipe but when I checked my oil is not mixing up there by the motor my check engine light is on and I got that check and they said change or clean out the EGR and I changed it and cleaned it out because before I had the white smoke and the white oil it was pumping out a lot of gas and white smoke out of the exhaust I clean that and put it back on now I have a white milky substance and and smoke coming out my exhaust when I park the car it did not smoke or do that

My car has 1890000 miles.
My car has an automatic transmission.

In most cases, the white smoke is an indicator of coolant finding a way into the combustion chamber. This could happen through a damaged head gasket or a crack in the cylinder head or engine block. Most of the time, this would also be followed by milky oil or overheating problems. However, it could also be a problem with the EGR system, or an extremely rich fuel trim. The best thing to do is have a professional mobile mechanic complete a smoke coming from exhaust inspection, so they can pinpoint the source of your issues and recommend a repair.
