What weight oil are you using? All you need is a good brand of 10W40 oil and a good oil filter (do not use Fram). Get a stethascope from the auto parts store so you can find out exactly where the ticking is coming from. Why would you install a fuel pump with that many miles on it on a rebuilt motor.
