    I really can't remember. It may have been on the lighter side since i ran tight bearing clearance but i am not sure since i remember at times pouring in bottles of 20-50. I have been known to mix weights too.

    When a bearing surface gets a hard shock from something like detonation the multigrade oils tend to temporarily break down to the low weight number. So by mixing in a bottle or two of heavier oil there are still stronger/larger/more protective oil molecules in the film to help protect the bearing surface from metal to metal contact.

      I tried tapping the valve yesterday, but the inner sleeve would start to rotate making it not possible to tap. You'd need to tack the pieces together to stop them from spinning. But I may just tack a restrictor plate to the top instead and call it a day. Hopefully I'll be successful today since I set a valve on fire yesterday doing that shit.

        Hum... I did a few of them and never had the inner part spin. You could try to squeeze the vice a little tighter. I used to have vice jaw marks in the outer sleeve after I was done making one.

          I wonder if that bypass valve that I got from RA was to replace the Oil Filter bypass valve, not the Oil Pump bypass valve...guess I'll check tonight.

            nvm, there is no oil filter bypass valve in the block. I have no clue what RA is selling then.

              What did you come up with on this? Were you able to tap the valve?

                I ran out of valves to tap and ended up booger welding a restrictor plate on top. I wanted to avoid marring up the outside of the valve with my vice grips since It would gouge the TCC, but its probably not a big deal if it does. I'd recommend going the tap route for everyone else. lol

                I don't have my gauges installed yet, but it seems like the oil pressure is higher since it caused my oil feed line fittings to leak down the back of my block a lot more than they did before. I'll be ordering a new fitting to weld onto a stock plug to fix that issue.

                  Man, with my H.C. engine, I was seeing 80psi cold idle, over 100 revving, 15 hot idle, and 60-70psi at 3000rpm hot. This all on 5w30. I never even thought about the bypass valve.
