hey i'm new to ls1's owned nothing but the blue oval and finally tried brand x aka chevy. anways i think i know a blown head gasket when i see one but this one has me stumped. i got a 98 z28 with 84k on it. apparently at idle itll show some white smoke not much tho. at WOT black smoke comes out which tells me fuel. pulled the plugs their whitish with a pinkish tint to them. white tells me lean but black smoke tells me rich, the pinkish tint i assume is coolant seeping in? oil isn't milky. car isn't overheating its running between 160-180 apparently a lot of ls1's run at 210 so i assume this car has some tune or maybe a dif thermo. but the white smoke has me stumped do you think its blown head gasket.

Do you use fuel injector cleaner? Mine were pink last time i checked..was hoping it was just the cleaner.

is the white smoke at operating temp,then it mite be a head gasket.do a pressure check on the coolant system.any ses lights?

Hmmm I did use fuel injector cleaner I can't remember if I did it before or after I pulled the plugs
