Jim, I had the same problem with my '48 engine rebuild. The two plugs that had to be removed were the one the shop installed in the crankcase vent and the one they added where the oil pressure gauge is installed. I tried everything to remove them, but eventually ended up drilling and using an "easy-out". I left the one on the rear of the engine, that is normally used for priming oil pump, alone, because I felt my luck with the "easy-outs" was running out.JGtools":sq10bm3j said:Barnyard, I don't know what the machine shop used as a thread sealer, all the threaded plugs on the block had some kind of blue stuff on the threads I should have tried removing the allen head plug back by the oil pump, before installing engine in frame, lesson learned, it is stuck tight, and not moving
Exactly. But as mentioned - that plug is often very hard to remove. The hole accessable through the oil filter housing also runs to the oil pump and will prime the pump. It also gives you a visual on whether the pump is primed or not. If you crank the engine over and oil comes out of the hole you know the pump is primed.NJ Farmer":2d3ior3x said:Correct me if I am wrong but oil pump is located in the left side of the engine (when looking at it from the driver's seat). Isn't the correct method to prime is to remove the allen screw on the upper LEFT side of the rear engine (above the hydraulic lines) to prime the pump?....You really shouldn't need more than a tablespoon of oil to fill the oil pump cavity. I'm sure there is more than one way to prime the pump but I believe that what is stated above is the correct way to "prime the pump".

The plug was not intended to be an access for priming the oil pump. It closes up one end of an oil gallery.cubbrian":3gbl2567 said:Why would the engineers put the access directly behind where the lines are ran anyway? Would and inch either abouve or below not work?
