GM/Chevy V8 Oil Bypass Sealed With 1/4 NPT Plug. FelPro Summit 1 Piece Oil Pan Gaskets Too Big? PT1

Part One of lower rebuild of a 1978 305ci. Bearings, oil pump and other stuff coming soon.

OEM GM oil bypass came out with just a flick of a fingernail. Tapped & Plugged with 1/4 NPT anodized well... plug and JB Welded into place. You may wish to get an oil filter without a bypass built in if you're going in on this project. Super clean rear bearing cap and oil pump mount. New Summit oil pan is solid but a bit more shallow but I don't think the oil loss is that great and it may make it easier to fit in a tight spot. Decided to leave "hidden" oil plug up inside the block. Fill your new oil filter with oil before fitment? Yes for me but that's up to you but it will take much longer to prime and fill the system. Using the "ZERO" function on a digital caliper to help figure some types of measurements.

Please only do what I do at your own risk.

I have some information on Odysee too if you'd like to check that out and I also post these on Rumble and X.

Thank You for watching
