Hi Bewy,
Here is why I ruled out the comp rockers. Physics sez fluid goes with gravity, into a cup. You need
push rod oil pressure to fill cup upside down, shaft rockers oil push rod with squirt hole. Push rod
choices are a non issue with a cut to fit/press in top and adjustable checking rod. And 12" cheap
vernier caliper/cutoff wheel/ drill and 1" small belt sander to square tube and press or tap in tip.
A cheap Harbor Freight lathe is a push rod master piece. We are talking under 6000rpm street/endurance high mileage here not high rpm racing setup. I prefer cooling/lube oil in a cup
like in the top of the lifter unless you have psi to keep it oiled.
Out here in the western US the only fluid that flows uphill is water going to money.
Thank you for your reply,
Rick
