Ring problems??
Ok I have smoke coming out of the brether on the valve cover. It was a fully stock ls motor and it was doing this. I bought a VTEC head and slapped it on and the samething. I get shitty shitty power from this setup and even when it was an LS. Now VTEC opens but it's super weak. Timing is on point. The block is a 95 with a type R head(B16 everything). So do you guys think it';s the piston rings causing the problem? Thanks for the help. Im gonna do a COMP TEST and see what #'s I come up with. I think 175 across the board should be good right? Thanks guys!

I'm not a betting man, but it's likey that the piston rings are shot. It is possible that the valve seals are shot on your VTEC head, but that wouldn't explain the lagging power with the non-VTEC head.
If the compression is low on a given cylinder (>150), squirt a fine mist of oil into the combustion chamber and re-test that cylinder. If the numbers improve, then you've got your answer.
As you rebuild, take the time to fit the GSR oil pump and block girdle. If you've got the budget, you might as well upgrade to forged pistons and rods. At the very least, upgrade the rod bolts on the stock con-rods.

if it was bad rings, you would also be burning oil on a weekly basis, and having to top it off a lot, and it would smoke on acceleration. If it's valve seals, same thing, but it will smoke on deceleration, or right after with a little back fire.
