got a ? for you weekend warriors about my 91 mr2 turbo. Upon start up it blows white smoke from one of the exhaust pipes. A big cloud at that. Also it has a slight hesitation. what could be the problem? I am thinking fuel injectors are dirty but I added some cleaner to my fuel to see if that helps out. I forget if I have a cat delete or not for the exhaust. Any ideas? thanks

valve seals are probably worn out. Same thing happens with my N/A... then goes away 2sec after car is started.

If it were valve seals the smoke would be blue (oil!). It could be normal condensation, but you said it was a large cloud. Does it smell sweet or in any way funny? I'm thinking more along the line of headgasket..
