[QUOTE="atafonso, post: 604149, member: 23592"] The higher pressure springs for the oil pistons will only increase pressure at high rpm's, it does nothing at idle or cure low oil pressure problems on worn out engines as many believe. 20 psi would be good if the engine was idling at the correct working temperature. At 60 deg the engine is not fully warm and the oil is still slightly thick, so pressure will drop after a long run when coming to a stand still. Probably you have too much clearance on the rod bearings, and/or rod sideplay. In your case, if you used a 30mm pump you would increase the oil film thickness and therefore it would create more pressure. Also a 20w50 oil would do the trick. Abel [/QUOTE]
