Priming an LS motor; new build

[Lynn]

Rigged up a priming system using some old schedule 80 pvc that I already had on hand. The only piece I had to buy was an end cap to glue on. Had all the hardware on hand. Even had a small regulator already attached to air hose.

Found multiple videos on line.

Ran about 5 quarts through the priming port while slowly rotating the engine. Got oil to squirt up through every pushrod except #1 intake and exhaust.

Can anyone tell me if that is normal. I am fine running more oil through it and rotating until I get oil up through those two. Just didn't know if it was normal for some to take much longer than others.

Update. Had no time over the weekend, so went down to the shop this evening after work. My pressurized reservoir only holds about 2.5 quarts. I anticipated draining the oil and refilling it a couple of times. Probably refilled it at least 10 to 12 times before I was done.

Took almost another hour of running oil into the priming port (varied from 20 psi to 40 psi). I wasn't sure if increased pressure would help. But, I can guarantee 2.5 quarts runs through a lot FASTER at 40 psi.

Kept thinking I would get some oil on those two. Finally got oil on #1 intake after about 45 minutes. Had to run another 7.5 quarts through to get oil to the exhaust rocker.

At least that part of this job is done.

Engine will still be a bit noisy on startup, but it will settle down. I assume you are dropping in a bone stock engine so there was no need to measure preload for pushrod length.

Correct. Reman long block.

Started on the first try. Not even one tick. Runs perfectly smooth.
