Oil pressure woes
#62
Hey Kevin,
Very depressing news. I know you're bummed.
I agree with the other Kevin that you can help things by priming the pump by pouring oil down the outside hole. I have gotten so paranoid regarding this issue that on my last rebuild I "bench tested" the oil system while it was still on the engine stand. I will say that for that particular engine, I spewed oil out of the oil filter housing (oil filter removed) with just the starter and a good battery. I would recommend you try the prime, make sure your battery is fully charged, and check for oil at the filter (versus the OPRV) as that is the first stop past the oil pump. And don't forget to put oil back in the oil pan!

I will pull the plugs, pull the filter pour oil in and let her crank.
The defeatism lies only in the fact that if this doesn't work. It'll mean pulling the motor, again, which is really not feasible at this point. I need a daily driver. My wife is really tired of being stuck in the house.

Van has a point, pulling the plugs will allow the starter to spin the engine faster and the battery will last alot longer. If you go that route I would pull the fuel pump fuse or dme relay, so you dont have fuel spraying out the spark plug holes or excess fuel washing you rings of oil.

What engine is it? Not a great idea to turn a 16v backwards if you have one.
When I indtalled my rebuilt motor I was never able to get a prime on the starter. I started it and got pressure within a second or 2 so I let it run.
I know exactly what you are going through I never solved my pressure problem and ended out buying a used engine and rebuilding it on a stand and then dropping it in my car.
I have mostly taken the old engine apart and I still am not sure what the problem was.
Don't give up!

Pulled spark plugs, removed oil filter. Poured oil down the "hole" on the side of the boss. Oil started running down the filter boss pretty quickly? Put the jumper cables on the corolla and spun the starter pretty much until I figured it would be burning up. Light never went off. Pressure never rose above 1.5 bar.
Took filter off, poured more oil on the driveway from the filter boss, cranked again without filter on, not a spurt or additional drop of oil to be seen.
I'm so discouraged at this point.

Untill you put the filter back on you will not get real pressure. If you have some pressure you should try with the filter back on and run it. At 1.5 bar at idle you cant hurt anything and see if it picks up to 4 or 5 bar.

As Van mentioned and I forgot, I spin the engine with the plugs out, on the starter, and get oil gushing out of the filter mount, with the filter removed. It will be very obvious. Yes, you can't build full pressure with the filter removed but if you don't get oil coming out at the filter mount while cranking, you're dead, you've got a significant problem somewhere. I'm not sure why you would even show 1.5 psi with the filter off. Whatever, having the filter off takes the OPRV out of the equation, as it is downstream of the filter. To the best of my knowledge!

One piece Oprv. But the oil isn't even making it that far. At this point I have to deduce that the problem is the seal between the block and the "girdle" a friend who was a service writer at Porsche suggested over filling the motor. I guess if I poured enough oil in to get up to the bottom of the girdle that would allow me to know if air was getting in from there.
