One pushrod flows a lot more oil than the others. Problem?

I primed my motor last nite, and the #7 intake rocker fills with oil & overflows within in a couple of seconds, but all the others just have a trickle. Rotating the crank didn't change anything. What would cause this, and do I need to take any action? New build, but I reused the original lifters.

Thanks.

One of mine seems to do that as well. It flows a lot more oil than the rest of them. Not sure if it is a problem though.

I am sure you are fine, the drill does not recreate the same pressure that running motor will create. The lifters tend to be a little inconsistant at lower NON operating pressures.

Thanks for the fast input. Nice observation on the lifter inconsistancy at low pressure - that makes sense.

On with the intake install. Great fun on a sunny Sunday afternoon!
