Ok so heres the deal every1 i have a brand new engine with new rings and all that jazz ,D15b7.. At higher rpm it smokes and i think it could be because i had bad rings and it smoked with the d15b1 engine so theres ALOT of oil in the exhaust do you think it could be the old oil burning off cuz the temp at higher rpm or do you think it could be because valve lash needs adjusted? ANY HELP PLEASE!!!!!!!!!!!!!!!!!!!!

 

It could be a few things. Like the pcv system blow a ton of oil at high rpms. Has the head been re-done(a valve job)? Or it could just be burn off. Is your oil level droping over the course of a few days?

 

No oil level is fine its probably a combo of pcv, and oil burn off in the exhaust.. It had new valves and everything the valve lash needs adjustment and has port and polish and other mods nothing to major tho.. Thanks for the reply tho
