Totally Confused
By John - 01/17/2001 8:29:24 PM; IP 142.177.70.52
All the talk about oil systems for the FE has me completely confused. Besides the common mods of flaring and enlarging oil passages and restricting the heads, most prople recommend 0.0025 bearing clearances with 20W50 oil, a M57HV pump and Milodon oil pan. But some people are running a stock oil pump with 5W30 Synthetic and the same claearances.

My problem is main bearing oil starvation on cold start-up and also during hard acceleration when warm.

Doesn't a HV pump and thick oil add to the oil starvation problem, by circulating oil too quickly and slowing oil drainback?

But, doesn't a stock pump and thin oil cause a problem with 0.0025" bearing clearances which are greater than stock limits?

This oil system seems incredibly touchy with these engines, and the oil starvation problem seems a common one. But many of you out there never seem to have a problem despite the differrent methods you have used.

What is the story here? I'm totally confused!
