Chief, If you had the original oil pressure nipple, those are prone to failure. If you got it out clean (with the easy out
), now all you need is a proper tap to clean the threads for a new pipe nipple (brass!!) - I had to do this with my stbd aft block drain two years ago, as the nipple was epoxied to the block
There are lots of pics floating around here of that, I won't repeat them. Check out my "old boat, new owner thread.."
