what did you do? new motor build? heads cam? could be anything really check your pcv system first thats the cheapest, next would be valve seals and then piston rings.

2001 ls1, cam swap trex, pac springs, 80mm tb, engine has 67000 miles.. no way rings holding that good of compression??checked pvc its good, only thing it only pulling about 10-14 on vacuum and didnt know if that was normal with that big of a cam... plugged vac off on side of intake and bothe small llines behind intake are plugged.. when i first fired it off it didnt smoke at all, went to put exhaust on and ever since it smokes when it gets up to temp..
