burning oil after cam install
burning oil after cam install iv always figured this was normal but i thought id make a thread to make sure.
before my cam install, the car wouldnt burn a drop. now it will shoot a decent amount of blue smoke out when i go WOT. its not enough for me to see but my friends that drive behind me have told me they can see it. is this normal?

well i pulled the heads off a couple months after and all the valve stem seals had popped loose so i bought new ones and rtved them in. mainly getting oil through pcv
umm yeah, having to RTV the valve seals is the problem
. Did you lightly tap them into place with a socket and a rubber mallet? if not thats why there coming loose or popping off. you need to NOT RTV them. jeesh Trending Topics

Verdad Gallardo iv pulled my intake off too many times to list and has never changed. when i got my Ai cam kit, it came with new valve stem seals and the tool to install it. i put them on dry. a couple months later i pulled my heads off and they all popped off so i bought new ones and rtved them

You were supposed to lubricate the seat on the valve guide with merely a drop of oil, which is just to help the valve seal slide into its place with ease.
I guess you have some valve springs to remove

Neither of those would cause that. How could rocker studs cause it to burn oil? Lol think about that.
The intake bolts dont call for any sealant either, just the gasket...
Your RTV'd valve stem seals are the issue IMO.

well my buddys car was burning oil because there wasnt any sealent on his rocker bolts. took them all out and put sealent on them, no more smoke. but he has an ls1. i didnt no if that was common between the 2
Some heads have the rocker studs/bolts that are drilled into the intake runner. This will cause the oil to be sucked around the stud/bolt threads. Pontiac Edelbrock heads have this problem. Some SBC heads have this problem also.
Only if they were heavily ported.
Im 99% sure stock heads dont need any sealant on the rocker studs. Lloyd made sure I knew wich ones would need them when I got my heads back from him, by putting black Xs on the stud holes that go into the runners
