If I do a reline pull and then quickly come to a stop I am greated with a big cloud of white smoke. It clears up in about ten seconds. any thoughts ? I'm running 100 to 1 premix. stock ecu.

thanks for the help

What you describe sounds like a high-vacuum oil blow-by(suck-by), but that would be blue smoke. White would be coolant.

what would cause the high vacume and what is the cure. I don't think it's coolant .

I have smelled that way to many times. Can you think of anything that could cause a temporary over rich condition.

thanks

do you think you blew a coolant seal?

probably coolant seals starting to go. Under high rpms there would be more chance for them to leak thus cuasing the smoke.

Overfueling would be black smoke.



Are you burning an extraordinary amount of oil?

could just be blow by since its only at high rpm and high boost. are you losing coolant? or oil?



oh yeah.. abruptly stopping causes very high vaccuums

sounds like what happened with my hubbys 87 GXL... as i recall it was the oil control rings, but it wasnt really white, but it wasnt really blue either..



only happened when he did a high rev and then hit the clutch... was good when people tailgated..

could also be tranny fluid or oil leaking onto exhuast or something and burning off.
