Well the jury is still out in my head on that one. I was running the "performance" oil cooler, and it ran hot. Even tried new hoses. I switched back to stock at PAt's and it's a bit cooler, but still hotter than the average. I'm wondering if it's going to be the elusive piece of shop rag in the oil passages somewhere. One of these years I wanna do a big bore, I guess I'll flush it all out then. Until, then I am not sure how I could flush the oil passages out, ya know? That's the only thing I can think of, maybe it's just not circulating well.
