Doesn't really knock or make any noise that I can perceive. Main bearings are an interesting thought. The oil pressure at idle when fully warmed up is around 15psi, I think that may be a little low. Oil pressure at cold start is in the 70s, and seems to be around 45-47psi at 3-4 rpm when warm. It does have 987 returns (now) and the updated 987 oil pressure bypass spring/piston.
