sweetpotato Posted June 19, 2015 Share Posted June 19, 2015 I'm trying to increase my oil pressure. I have the pan down to replace rear seal so I took the oil pump apart to check specs. The clearance is good between the top of the pump body and the top of the helical gears. The book says it should be .004. One gear is .004 and the other is .005, However, it had a gasket between the body and the cover and it measures .009. The book makes no mention of a gasket or whether the recommended .004 clearance is what it should be when the cover is on. Obviously my clearance with the cover on and using that gasket is going to be .013 or .014. So, should I install the cover without a gasket , cut a very thin gasket , or use the gasket that it has now? Will it work without a gasket?
