Well i decided today it was time to start swapping my stock heads with my home ported 243's. Well started off drained the water, then pulled the truck into the shop. proceeded with jacking up the rear to drain as much water as i could. Let it back down and proceeded with removing the manifold and throttlebody. Did a quick inspection of the bottom of the intake (i have a Fast 90) and see i didnt grind some of the bolts short enough not a big deal since it just kinda scratched it up where they rubbed. Well i proceeded with removing the pass. side header bolts. Got them out and was just kinda screwing around and noticed something down the #2 cylinder intake runner on the head. So i stuck a rag on the end of a little rod i had lying there and stuffed it down the runner to the valve, pulled it out and got a nice wiff of GAS, but it looked a little like oil!!!!!!!!!!! So im wondering how could this happen?? Well i looked in all the runners on both heads and all the ones that were fully closed had gas smelling stuff built up in them. I think this is all of my oil consumption issue.

I recently went to the LS6 style PCV system and it did help some but didnt cure anything. I also noticed that when i first installed it, i could crank the motor and go pull the oil cap and it had a good suction, now it doesnt!!!!!! Whats up with that??

 

You might need to change your valve stem seals ,plus you may have a leaky injector also

 

Do you use a catch can?

 

no sure dont but i have been considering one for a long time

 

I might start there and see if you can trap some oil. Start with the easiest and cheapest things first.

 

yea but i would like to get an idea of where to look to fix this problem

 

Thats the first place I would look. Then the seals I suppose. You dont have an issue with popping the dipstick do you?
