Let me finish, Just broke in my 454 chevy engine with edelbrock alum heads. It all went well, then changed the oil and filter, now there is a small 1/8 layer of oil in my coolant over tank, I didn't retorque the heads becuase fel-pro says not to do so. Any ideas what it can be. Checked oil in pan and dipstick, no milky stuff and no white smoke coming from exhaust pipes. runs real strong. any ideas please help???

Are you running an automatic transmission? Any chance the heat exchanger in the radiator has sprung a leak. If you are running an auto check the fluid and radiator for strawberry milkshake foam. If it's just a small amount, could it be oil that found its way into the cooling jacket during assembly? Oil floats on water so the radiator and overflow would eventually skim out any oil that found it's way in no matter how small amount it was.

Well I'm running to heat exchanger, but it is a brand new motor. Should I just try toget what oil is in the over flow and see if it collects again??

I had the same problem with my brodix heads. Did you put any sealant on the head bolts. Try putting liquid teflon on the threads. It is a pain in the butt to pull all the bolts. Do them one at a time.

Also when I had this problem it was milky on the inside top of the valve cover and there was a little moisture on top of the heads.

I would personally drain the overflow and refill it to the proper level with coolant, and see if it happens again. If your radiator & oil don't give any strange clues (like those listed above), then the engine's vitals are more than likely good. Take it for a drive and see what happens.
