Priming New Motor
How long should it take for oil to reach the rocker when priming an engine? Using an old dist.(spinning it clockwise) and rotating the crank every couple minutes, but after 30 minutes only have 1 rocker with oil coming out. System is pressurized, and seems to stay that way after about 10-15 minutes after stopping. I can feel the oil pump "loading up" after about 2-3 seconds, the drill starts to receive a load from the oil pump. I've triple checked to make sure it plumbed correctly, but want to make sure I'm not doing anything wrong.
Thanks-

Re: Priming New Motor
There was a similar question about this some time ago, a good search might find it. I had the same problem on a rebuild. Went ahead and fired it up and oil came to the rockers in 10 seconds. I fired up because I knew everything was fine. Not sure why but it seems that drill priming just does not get oil up to the valvetrain.

I think Reed's answer sounds plausible...

Re: Priming New Motor
maybe you are collapsing the prime out of the lifters when you rotate it by hand every few minutes. the valve spring pressure is enough to drive the oil out. just a thought

Re: Priming New Motor
As long as the crank and rod brg's are primed you should be fine. I'm sure you lubed the valve train before for assembly. Let it rock! I don't know your valvetrain but if you use a COMP Extreem cam you will have valve noise no matter what you do because of thier fast ramp rates.

Re: Priming New Motor
Thanks for all the help. After about 45 minutes of running the drill on it the oil finally made it through all the push rods and to the rockers. Seems I put just a little bit too much assembly lube on the ends of the push rods, the oil squirted all over after it cleared. Also, I had the rocker arms a little to tight, readjusted the rockers so the push rods spin with my fingers, then added an extra 1/2 turn. Running Morel Roller lifters...

Re: Priming New Motor
I had the same problem using a cheap primer tool. the oil was bleeding out down where the dist. gear was supposed to be. I freaked out, but it just ended up being f*cking Autozones fault again. I took the gear off my dist. and it pumped right up.
