'69 Engine Parts

I have to disagree a bit here. If the oil filter parts are not installed properly, like missing the cup or the spring, the oil will just bypass the element without being filtered, but the oil pressure doesn't suffer.

I think that RiverPatrol suggestion of a manual oil pressure gauge is the best. You have a number of oil plugs on the engine block that can be used for this purpose, at both sides of where the oil base attaches. Check the oil pressure with the engine hot, both at idle (min. around 7 psi) and at 2000 rpms (around 50 psi).

I finally got under it and drained the oil yesterday. Swooooosh. Out poured and splashed an unexpected watery solution of a nice fuel/oil mixture. After cleaning up the mess, I really started worrying about what would cause fuel to get into the oil. A little online research resulted in learning that a primary cause can be a leaking fuel pump diaphragm. Pulled the fuel pump off and apart, and although I don't see any tears, it is so old and brittle that I am surprised it isn't breaking up like a Ritz cracker. I noticed that the parts inside, under the diaphragm, are all rusty (surprising). So I'm 'assuming' it's leaking. My old brain cells are thinking and hoping that both my leaks and low oil pressure could be caused by the oil/fuel mixture. Now to find a replacement pump or rebuild kit. Any thoughts in that direction will be appreciated.

That makes so much sense! In a way, good news.

I saved this info some time ago. This is the fuel pump for the P40 engine used in fork lifts, which is the same as the one on the P engine.

Hey there Walt, May want to put a cheaper oil into the engine on first round when you refill it. Then check your oil pressure. If the bearings are still good, then you can swap out to a better oil. If not, you may have eaten the bearings up due to the low pressure. Good Luck.

Long overdue update on the rear main ( and other) seals. I hoped that clean oil would cure the leak (knowing the odds to be about 1 billion to one), and for sure it didn't . I took a little road trip, 125 miles each way, over the weekend and not only did the rear main leak, the tranny and transfer case joined in to make it a three-some. They all leak like spaghetti strainers. Several stops and messy refills, but it made it up and back . Guess I really have my work cut out for me now.

Hey Walt,
Sorry for the setbacks but please chase these leaks down and one by one it will be worth it.....
....and if it is any consolation.....you think you have problems?!.
