Fluctuating oil pressure... any advice??
So I cranked over the LQ4 for about 15 seconds, got no pressure. I started it for the first time and got 0psi oil pressure for a couple seconds. I let the engine cool down for a couple minutes, started it up again for about 5 seconds, let it cool.
Did this 3 times, and I finally saw some oil pressure, but it goes up to about 30psi, fluctuates a lot, and if I stab the gas a bit it goes up to 50psi but then down. I have an oil cooler and I filled my pan up to proper height with 6 quarts.
I was expecting it wouldn't reach full pressure immediately at first start because of the added volume of the oil cooler and lines, but I don't want to risk messing the bearings up. I was thinking I re-try tomorrow but just crank it over for a much longer time. Also after that try and keep starting for about 10-seconds then letting it sit.
Anyone have any ideas or advice? Does this sound good/bad, or did I just not try enough today and I should or shouldn't keep trying again?

Also, it's a modified pan and oil pickup. The pickup has about 1/2 clearance to bottom of the pan, and from what I remember the pickup/oring bolted together all nicely and smoothly, but after reading other posts on oil pressure issues, I'm starting to get sketched out on that oring connection, and I really dont want to have to pull the engine to remove the pan to check it out.
