If it has never been removed it can be really difficult to get loose. Usually some heat and a tight-fitting square-drive removal tool are needed.

Hopefully the engine machinist removed the original plug to properly clean out that oil passage, then later on it was replaced by the engine builder with a new hex-drive plug during engine assembly.

Morning, fellas. Two questions for today:

1. Regarding the 3/8" fitting by the distributor for the oil pressure gauge, should I buy a 90° elbow to connect the nylon hose to so it's not coming straight up from the block so it's less likely to kink?

2. What did you guys think of my oil filter autopsy? Look ok?
