I took my car to the track and made a few passes. The car was smoking real bad so when I poped the hood there was oil all over the pass side header. The breather I put in the valve cover was soaked with oil and was leaking down on to the header. I also had a bunch of oil on the floor of my intake. My motor has 500 miles on it, has a LS6 pcv system and a fast 78mm intake. What could be causing this?

You are getting more blow by past the rings than the pcv system can evacuate and pressurizing the crankcase.

What would cause this? The motor is new. Could this be why I have no top end power?

I would do a leakdown test. Possible the rings are not seated yet, but current technology rings seat pretty quick if the cylinders were honed to the proper finish. There is also not a whole lot of vacuum in the intake at WOT/high rpms tp evacuate the crankcase through the pcv system. Have you consulted the engine builder, or did you build it yourself?

Does the breather have a deflector on the backside, or is it a wide-open hole? Look at the underside of a stock valve cover, and you'll see a deflector that sits between the oil and the breather tube. If you have a straight shot with no deflection, you'll pump oil like a well.

Well the oil is coming out of other area as well, it keeps pushing out gaskits. So I guess I have a ring problem. I built the motor myself.

I had this happen to me and it was a ring that let go.
