And I'm sure arrogance has worked for you?

Forums, by nature, are a place where people are supposed to share knowledge. Yes, you gave your 2 cents, which is theoretically knowledge, BUT it in no way pertains to my question. If I wanted advice on oil pumps, I would've asked before I put the motor together. Your other reply, with the engine builder remark, was entirely off subject. So if you must, beat your chest and show your Internet superiority.
