hey i gotta ls vtec in my rex and it will drive fine 4 a half hour the it starts to smoke really really bad but only for 10 15 mins then it kinda stops, but it always drives fine no oil leaks and noise. i have a b16 head and a ls block with the golden eagle ls vtec kit, and arp head studs, any clues on what it could be? HELP PLEASE, ASAP, thanks

 

Sounds like rings, Whats the condition of the bottom end?

 

the bottem end has only 40k on it, but when rings go out they usely smoke when u get on it or just drive normal.
