I have 48k miles on the car. It's been modded, cam, ported heads FBO. Last few years it's only been a track car.
I had an issue with the original set of ported heads I purchased, the intake port was ported too much and allowing coolant to flow into the port, burning it and also getting in the oil. It was pretty difficult to diagnose, I was losing coolant and it wasn't smoking and the oil appeared fine. After getting an oil sample taken and seeing the coolant in the oil along with excessive wear I took it apart and after a long ordeal ended up with another set of heads. Even after that my oil samples all showed more than normal wear and the 0w-40 oil wasn't really holding up even after 3 track days. It was going to fail eventually. I believe it was probably a spun bearing first even though the oil pressure was ok, and then the heat cracked the crankshaft. However it coulda happened in the reverse order also. I don't think I'll ever know.
