Hello, I just have finished rebuilding my 91 camaro. I have installed a lt4 hotcam ls7 lifters and 1.6 roller rockers. I tried to prime my oil pump for about 10 minutes. 2 rockers got oil real good, but the rest either got none or very little. I have 60 psi so I'm gettin preassure. I tried primin with a drill. Any idea what is going on? Perhaps I Need new push rods? Thanks to anyone that can help.

 

You need to rotate the engine while you prelube. when you see oil rotate 90 degrees

 

Thanks. Il try it when I get back. I have had ppl tell me to fire it up just put oil on the rockers myself and it should straighten itself out. I let my lifters soak but i don't think they have soak up oil yet. Do you kno if my stock pushrods would work?
