Rebuilt engine / forgotten oil gallery plug in rear of engine
Bob, well my worst fears are confirmed. The plug is out. Got the engine
started. 25 lbs cold, 10 to 15 lbs warm. Took a valve cover off, almost
dry. Took the distributor out, used a better drill and a solid stream
of oil came out the plug hole about four inches into the dist. silo, at
the front of the engine, Used baling wire to probe the hole, no plug.
Stupid machine shop, stupid me for not checking. Engine is installed.
Is there any way to get the plug in through the dist. hole? What size
and threads are the plug? Any suggestions besides Hari Kari?

There's no need to be upset; engines operated like that are rarely
damaged because they DID HAVE oil pressure, just not enough. I'm sure
you didn't go out and drive it at high speed or anything, so most likely
NO damage has been done.
The bad news is that I don't know any way of wiggling a plug into that hole and being able to screw it in place without removing the bellhousing from the engine so you have a "straight shot" into the plug hole. The plug itself is a standard pipe thread, but I'm not sure of the dimensions. Probably 1/2" pipe, maybe bigger.
Once you have removed the bellhousing, you will see a corresponding pipe plug on the rear of the engine block on the OTHER side of the engine. You can easily remove that pipe plug to get the right dimension for the one that's missing...or go back to the machine shop and ask if them if they "have any parts left over." Ha! Like they would admit it. Finally, on the BACKside of the distributor silo, there will be what looks like a simple freeze plug in place that must be pried out to access the distributor silo so you can insert the plug through the silo, so to speak. That "freeze plug" just serves to keep dirt and water from inside the distributor silo when the bellhousning is bolted back on the engine. Be sure to replace that freeze plug (really an access plug) after you've installed the missing oil gallery plug.
Thanks Bob. I'm sick about this. It looks to be a 3/8ths plug, I'm
checking the chassis manual tonight to see if there is a listing. I can
see the hole, that is what is frustrating. I guess dropping the tranny,
removing the flywheel and stuff and then removing the welch plug
(freeze type plug) must be the only logical way of doing this short of
pulling the engine. I have all sorts of junker engines. I'll pull one
of those plugs. Again, Thanks for all the help you always selflessly
offer. Surgeons do much more complicated things in a smaller space, but
hey, I'm not a surgeon (I feel more like a butcher right now).

Bought a wrench from J.C. Whitney called the side winder in 1/4".

"Looking at the back of the engine, it is on the left side of the cam about 1 1/2" inches behind the 1.25" freeze plug. Looking down the dist. hole it is on the drivers side. It is a 1/4" taper pipe plug."
