So here's the jist. I rebuilt my 72 304 and it fired up almost instantly. I let it run for about 25 minutes and then removed the valve covers to make sure oil was traveling throughout and realized there wasn't any oil in the valve covers. The push rods, rockers etc. were dry so now I'm worried that i did something wrong. I pulled off the intake manifold and the lifters all have oil and the oil pressure at idle settled at about 25psi @ 700 rpm. Any thoughts of what might be the problem?
Petey, i did make sure the oil plugs were in and I'm using a flat heat bit socket on a long extension connected to my drill to prime it. I'll pull the covers and check. Jblue, i took the block to a machine shop for the honing, cleaning, etc. i put it back together myself as my first rebuild. I checked all the specs when installing everything. The valves, lifters, push rods etc. went in the way they came out. It's taken me 6 months to put it back together cause I'm making sure everything is in spec. Just getting hung up on this oil thing now.
Turns out it just needed more oil. Poured another quart and when i primed it it finally caught the oil and started coming out of the push rods. I feel like an idiot but now it's got 6 quarts in it. Is that normal for some CJs?
You never put a old oil pump in a rebuilt engine. That would be like reusing old gaskets on a new engine. Pull the old pump and replace it before you wish you had.Trust me I've been doing this for a living for a long time
I completely understand. I've taken jblue's advice and ordered the new pump kit. I have a different problem now though and I'm starting to think even though I'm mechanically inclined and not a total idiot, i might not be cut out for rebuilding engines. Thanks for the advice gents
