My 1996 mazda Miata puffs out white / heavy smoke after idling at light or stop sign.
replaced head gaskets and did all top engine work while it was apart. got it back and it still smoked a little and got worse the more I drove it. replaced pcv valve, still smoking, cleaned throttle body, still smoking.
after first work was done, I had some issues with the trans, it would not go into gear and it died sometimes, added trans fluid, and it did fine for a while longer, now trans fluid is down again but is not leaking on ground.
Is the trans fluid somehow burning off thru the exhaust?
I am lost and so is my mechanic. Please help
