opus Posted June 21, 2008 Share Posted June 21, 2008 Did a reseal, etc. Filled the filter, cranked it and seemed to get some pressure. Started it and 30 secs later it started making noise. Pressure gauge is messed up anyways and cant do much about it right now. Airlock?? Bleed? Any suggestions? '86 ea82 Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 21, 2008 Share Posted June 21, 2008 Put a regular mechanical gauge on it. The oiling system is self-priming so there's no way to bleed it. If the pump is working then air will be forced out. Did you dissasemble and inspect the pump? There's specifications on the clearances inside them. I generally opt for a new oil pump every 100 to 150 thousand miles. They get really chewed up inside - especially if people let the oil filters go for too long and the oil starts to bypass it through the pressure relief inside the filter.

opus Posted June 21, 2008 Author Share Posted June 21, 2008 I am also going to get a real gauge, but that that requires a trip to town, which I think we are going to do soon. I pulled the sending unit pipe out and got a big bubble of air. Everything worked fine then. Not too bad a job, only had 2 left over bolts.

Any pressure gauge will work - most have 1/4" NPT fittings so you just need an adaptor from the metric pump side (you can make one from an old stock sender - cut off the threaded section and leave some of the hex nut portion then tap it out for NPT), some nylon tubing (get the quality stuff), and some compression fittings. I have one made up with a 48" section of 1/4" tubing that I can use to test oil pressure on vehicles that I don't have a reliable dash gauge installed on. 0 to 60 psi gauges are a good choice. I get thrown-away used one's from my work every so often. They come as part of some equipment annual service kits so they get pulled and replaced even if they are good. On my off-road setup I use a stainless braided flex line with a 90 off the pump. Run that to the fenderwall and mount my sender or tubing up there where it's protected.
