I got a motor (93 h.o.)off some guy that had around 100k miles on it, I used his short block and replaced all the gaskets. After I put it back together I've been using synthetic oil. I have a small leak somewhere on the front of the motor which seems to be getting blown on other parts by the radiator fan and the alternator + the motor burns a little. Would it hurt or help anything to switch back to regular oil, do I have to flush out the synthetic first?
