The factory drilled the plug. It is shown in the GMC Maintenance Manual.
Dick Paterson has said in his engine rebuilding seminars that some people use the wrong plug, one without a hole, and the distributor gear won't get enough oil. It has nothing to do with the RPM of the engine or the volume of the oil pump.

Original motors we have opened up do not have this hole. This is why after much thought about it we are not doing it. I feel it's a hi performance option those hi rev boyd so-- that's not for us. I want a rock solid hunk of metal that runs on regular gas, can accept any oil and produces it's best performance under 3000rpm. No chrome, original valve covers, and all other visible parts. Needs to fire every time and have Bubba & Scooter be able to work on it. With or without the hole makes little difference, if GM felt it needed to be there, they would have done it even on Chevys!

Jim,
Ref: Maintenance Manual X-7525 / Section 6A / Page 6A/58 CAMSHAFT BEARINGS / Figure 65 / Camshaft and Oil Gallery Plugs
The left hand rear oil gallery plug is not shown. It is a threaded plug in the end of the left gallery just rearward of the
distributor. A small hole is provided in the plug for distributor lubrication. The cup plug shown provides access to the threaded
plug.
Ref: Parts book 78Z / Section 8 Engine / Page 8-2 CYLINDER BLOCK, CRANKSHAFT, OIL PAN
Page 8-4 / Key 31 - Qty - 1 / P/N - 588927 / Description - PLUG, camshaft rear bearing
Page 8-4 / Key 32 / Qty - 2 / P/N - None listed / Description - PLUG-oil passage (RH & LH)
Observations / Comments:
The MM notes; "A small hole is provided in the plug for distributor lubrication." Yet the PB does not provide a part number for
either of the plugs which IIRC means "local purchase." That is strange since they MM does not provide the diameter of that hole.
Things that make you go Hmmmmm?

PS - I checked MM X-7625 and found NADA, however, in MM X-7725 on page 6A-80 the same info noted in X-7725 is provided.

Yes, in a 300 CID Furd 6. Oil pump froze and took the drive gear (and the quill shaft) out. Probably saved the rest of the engine.

Bill, aren't the TSIO series engines alreadty fitted with oil spray to the pistons? We sold a bunch of airboat engines into the Everglades (All stamped NOT AIRWORTHY) when the welders were learning how. GSO-490 Lycs if memory serves.

Hey Guys,
Lots of heavy duty diesels have piston coolers, and so do all of the MB turbo-diesel passcar engines. There is a rule in engine design....
If you need cooling or lube oil there, put it there.
Don't count on it happening by chance, because when you really need it, it won't be there.
If you look around, you will find a few passcar motors that have a strange little groove in the upper rod shell that is matched in the rod forging. This is to put lube oil both on the thrust face of the cylinder wall and under the piston crown for cooling.

Matt, VW did cooler sprays on the turbo 1`600s but not on the NA 1600s (Both Diesels). They use a different block, which has led to grief when people triedto field add the turbo to the NAs.

Pretty much all of the VW/AUDI turbo engines (gas and diesel) have the piston oiler nozzles.
The 2.3 TD that Ford put in their 85-87 Ranger also had them.
