Warren,
I just don't see how you could get a drill driven primer tool to pump up enough oil to the top side fast enough to simulate top end revs...? Uless you figure out how to hook it up ot a high speed die grinder or something?
I prime all my engines to check for oil flow to each rocker before I button it up, and I have never got enough flow to even squirt out over the edge of the heads using a [high speed] drill.
My engine builder refuses to put restrictors because he says the oil needs to cool the valve springs and upper valve train.
My argument is why then have I lost several bottom ends because all 8 quarts of oil are pumped right up and out of the valve cover tube breathers (circle track valve cover setup) and all over the engine compartment as the bottom end cavitates and welds the rods to the crank????? He can't answer that one...?
So I put the restrictors in myself after I get it home and before I put the engine in the car.
I have never lost a top end because of lack of cooling oil, but I have lost several bottom ends because of pumping all the oil right out the topside...!
