higher RPMs cause oil vaporization and any blowby will push oil out any leaking area of the engine, even the oring around the filler cap.

While you are down there, check the block off plate above the oil filter where a oil cooler line would bolt in. Those leak a lot of times and the oil will run down on the filter.
or i could just replace the plate with an oil cooler...
but after this past weekend, i can't afford to put any moniez in the truck til the car's fixed
besides... the car needs the oil cooler more - i hit high 280s on a couple laps!
