    There is a good chance it could be the valve seals. How many miles are on the head?? If it has alot you should just pull it off a have a valve job done and get some new oem valve seals.

    You can lose some power when your valvetrain is worn. It wont have as much compression since there will be a little leakage past the valves. But from what i have seen these high revving vtec heads go through hell and they need a valve job at 80,000 miles in my opinion to perform at peak performance.

    Valve Seals, Piston rings could cause a burning oil problem

    You would have to do a leak down test to see

    engine could also be leaking oil and dripping on the header/manifold downpipe, causeing the oil smell
    just a thought.
    otherwise its prolly your valve seals, or at worst you didn't seat the rings properly during the break-in of the engine after you put the pistons in, and now the cylinders are oval. . . not good.

    a compression test isn't gonna tell you everything, I recommend you do a leakdown test, or bring it somewhere where they can do a leakdown test.
    Leakdown testing will tell you alot more about the condition of the engine, here is a writeup on how to do it. it's not a complete writeup, but it gives you a general idea on how to do the test.
