I have a 1998 Z28 Camaro that I recently put LT's on and an ORY. Ever since then it has had blue smoke coming out of the exhaust this only happens after i get on it and once in a while while i am pulling away from a stop light. It does it slightly if i rev it in neutral as well. I am wondering if this is caused by not having cats or if this something that is normal without cats? Should i be expecting to rebuild the motor? Any help would be greatly appreciated!

Thanks

 

LTs will smoke some after the initial install. mine was under the hood though. didn't notice any exiting the exhaust and def wasn't blue.

 

Checked the PCV valve and it is bad. I will replace that and hopefully it will help. Any other info you guys might have would be greatly appreciated! Thanks!

 

sounds like the valve guide seals are worn
