EA71 Oil Prime
Posted 17 November 2008 - 02:44 PM
I did not prime the oil pump, but there is oil in the filter. I ran the engine for 10 minuites as I said, mostly at Idle, but only brought it up to about 3500 RPM for a minuite, hoping that this would get some oil moving.
I hear no noise from the engine, and it sounds super smooth. Why don't I have pressure? Should I try and prime the pump? How do you prime the pump anyway? I know on 350's you take off the distributer and run a rod all the way down to the oil pump, is it the same for a subaru? If so, is this rod available at any auto parts store?

I also spoke with a guy at the local auto parts sotre just a few minuites ago. He told me to take the oil pump off, submerge it in oil and spin it both ways until it is primed. He said that it you don't do that, the pump will always have an air pocket in it and will not pump. It this true, or will the oil pump on a subaru suck up the oil and prime itself?

Ive heard of submerging a pump in oil befor but check your manual because I dont think it says anything about that. An old-timer recently told me something about packing with petrolium jelly first....
You sure that gauge is good? Harbour Frieght Wal-Mart Autozone.... I got a bad temp gauge once.
There is zero sign of life? Is the guage new? Any leaks?

check the dipstick
remove gauge from line, and remove filler cap from fill tube, put line into fill tube and run engine, check for FLOW
ALSO, what is the oil viscosity and ambient temp??
frozen tar will not pump

Im hoping that fillen er up with oil was a given.
If not you might be able to prime the system by sucking on that clear line till you get a mouth full. mmm non-detergent

I put in 10W30. I live in Louisiana, and when I ran it yesterday, it was about 60 degrees out. I did notice a small leak near the rear engine seal, but it's just a drip and only when the engine is running. I don't think that the leak has anything to do with pressure, or the oil pump, since the timing gears just pickup oil from the pan.
I'm going to try and manually prime the pump (which I did not think was necessary) and then use a professional oil pressure test gauge. I hope that this will tell me I have a serious problem or not.
I've heard about the grease, or petroleum jelly in the pump, but I believe that it is a very bad idea. Once grease gets hot, it will turn into oil anyway. But when its cold, its back to grease. I don't see how putting grease in an engine is a good idea, especiall after I just cleaned all kind of crud from the inside of it. That stuff will stick to everything ,and change the oil viscosity. Wouldn't the grease plug up holes and tubes that the oil is supposed to go through until it gets hot enough to liquify, maybe even clog up the oil filter? This may cause a starvation of oil to one or more critical places, like inside of the pushrods, crank bearings, etc. I HAVE heard of it, but sorry, I just don't trust the idea. It MAY work, but I don't want to take the risk.

If you take the line off of the oil gauge, you're correct, there should be 57 lbs of pressure behind that oil. Should shoot out pretty good!!!!!

Let us know what happend

I'm just stubborn though and won't try unorthodox methods. I feel safer that way. The wife tells me that dryer sheets will keep gnats off of you, but I won't even try that.:
Good luck with you rebuild. The guys over at CCR Engines gave me alot of helpful advice, along with everyone on this forum. Thank God for ultimatesubaru.

When I took apart all of the fittings, I found a bunch of gunk in there(I dont know how it got there)
Wen I cleared the line the oil pressure reads 60 psi @ 1000 rpm and 65 psi at 2500 rpm. Maybe this will go down as the engine breaks in.

At least its solved
