RE: My Pete rebuild I've been running it for a few weeks now. Running a new cast iron oil pump with no regulator shimming. The gear whine really stood out, but it has faded *some*. Oil pressure is extremely consistent. 22-25 psi hot idle, and 32-35 psi @ 1500 rpm. 3 small issues I'm in process of sorting out. 1- Oil seep at fuel pump. I swapped the fuel pump for a new recon last week, and the new one leaks also. It appears to be at the gasket, and just leaks a few drops over the week - enough to make a wet oil spot on the filter housing below the intake manifold. (IFSM housing is new) 2- #4 exhaust valve seals are leaking. I got the valve spring compressor and have new seals ordered. I'll pull the intake manifold and check all of the intake valves when I do #4, but I'm leaning towards just being either defective seals or damaged somehow when the head was assembled. The real head scratcher for me: 3- On most cold starts, I get a buzzing/vibration in the fuel line from the ECM cooling plate return to the fuel pump that lasts a few minutes. I'm not sure if it's air (or how air could get into that part of the system without a fuel leak being present) or just pulsation possibly from the regulator? Both pressure regulators are new (not that that means much). | |||
