I'm trying to prime my 350 SBO with oil.Yet despite me rotating it two full turns. I fail to get oil to the some of the rocker arms.

I'm wondering is my drill dying ( not enough RPM) Or keep rotating the engine and priming it. I do have 7 of them spitting oil yet not all of them? I'm ready to just crank it over with no plugs and see what happens?

Any ideas are appreciated.

It can take a while, sometimes up to 20-30 minutes. Are you using a good heavy duty drill, like 1/2" drive?

 

How long did you spin the pump? I have never had much of a problem priming a Olds, but I have had trouble with BB Chevys. It took a long time one time to get oil to the top. I was really getting worried, and finally, got oil. I read on the Chevy, that it can be a trapped air in the system. Maybe this is what is happening to you? I would keep priming, and turning the crank often. What size drill are you using, and what speed?

 

Make sure your drills in reverse so it spins the dist ccw

 

It's a 3/8 drill running in reverse and I'm running it wide open.

 

Rotate the crank 90° and continue priming. You have to get oil through all of the oil passages.

 

The stock lifters are quite restrictive at idle pressures; as Eric said 20-30 minutes to get to the rockers.

 

Priming the engine with oil seems to be a thing that varies from build to build. I did not even need a drill, just turning the oil pump by hand. In day 1 rotated the pump 20 min and got the oil to about half of the rockers. Next day again 20min and got the rest as well. If I had used a drill, I would be covered with oil and garage walls too

 

News Flash, Lifters were bad, The metering plates have no holes or notches in them!

 

That has happened in the past also. Weird it was half of them.
