I am pre-oiling the engine and the passanger side lifters are not recieving any oil but the drivers side lifters are all revieving oil. I have turned the engine several times and turned the oil pump but still the passanger side lifters arent getting any oil. Any ideas on what is going on.

THANKS a lot.

 

Are you certain the cam bearings are installed correctly?

 

I figured it out. I wasnt using a distributer to turn the pump so the oil wasnt going to ever spot.

 

Can someone explain this to me? I'm dealing with the same issue--using a AutoZone loaner oil pump primer, I'm not getting any oil on the passenger side lifters. I saw in another post someone else mentioned it was because I needed to gut a distributor and use that to pre-oil instead. (in order to get oil to the passenger side.) Why is that?

 

An old distributor has the rings in the casting that block off all the galley passages in the block correctly so that you get oil pressure in all the passages. If your primer tool is just a straight piece of rod with the slot in the end, it'll never pressurize the oil passages so that oil gets into all the lifters.
