I tapped the oil hole for a 1/4x28 grub screw and bottomed it on the cut threads with locktite. It's not coming out without a fight. I am able to use another 1.5-2 qts of oil, which is nice when these engines can burn 1 qt in 1,000 miles. This also helps reduce oil temps.

I will pull the shafts out of my spare motor too, when I go through it.

I need to redo the pistons on the current motor because of oil usage. And the spare will be a drop in replacement to keep the car running.
