No oil getting to head?

[John Mark Dongon]

I'm trying to prime my rebuilt engine but there isn't any oil getting to the lifters when I spin the oil sprocket with a drill. Has brand new 3g lifter I bleed them out before install, oil pump was reconditioned and did a balance shaft delete. I filled the engine with only 3.5 quarts is that enough to reach the oil strainer or do I need to put more oil?

Have you put anything in the pump to prime it, like assembly lube or some Vaseline/grease? It'll be hard for a dry pump to pull up oil.

Otherwise you may have a big air leak somewhere.

Figured out that was the problem! I put some petroleum jelly and now oils getting to the head! I didn't think lube would fix it, but your right!

Did you by chance inspect the shaft and gears, since they were run for a while with a low weight lubricant? Hate to have the oil pump take a crap from galling or scoring.

and all inside surfaces of the pump as aluminium is softer than steel..

@BLACK'98DSM nobody's arguing, I felt I needed reassurance I was being tricked by a perspective distortion haha. I thought I was going crazy but it makes sense when one looks at the centre round part of that gear

So your saying without any oil or lube oil won't get sucked up at all? Im pretty sure that lube just assist, but there should still be oil getting sucked lubed or not

You need the system primed appropriately for the pump to be able to pull the oil yes
