Galley Plugs, Which ones? Options

[Chad911sc]

While I have my engine out to fix my crank, wanted to do all the things I didn’t do the first time. I want to make sure I do all the galley plugs that are necessary to prevent one popping out and losing my oil pressure. Several posts on this forum say just to do the five, and some other forums say, to do many more. I got the main five out, and they were really in there! It took many pulls on the slide hammer to remove them. Surprisingly enough, my galley’s were spotless! In the bottom 2 pictures, my question is, do I need to remove these smaller ones up by the oil cooler? And also, what about this big one to the bottom right of the oil pump housing? Do these need to be removed and tapped as well?

Yes it ran with the .008 out crank. This is why I lost my oil pressure, it wiped the middle main bearing. It only ran for about 3 hours total and most of it was on jack stands trying to tune the carbs. But when I took it for a drive, once the carbs were tuned good enough to really put the gas down to seat the rings, it dropped the pressure to only about 4 lbs at idle. It had never gotten over 190 degrees in the driveway and would hold 8-10lbs. Once it got to 220 it lost the pressure, so I pulled it back apart. Everything inside still looks great and the case bores are perfect. I used a bore gauge to re check them and they are in middle of the spec on thrust sides.
