THAT BRITISH HUMOR IS JUST TOOOOO MUCH!!!! I couldn't stop watching!!
On a serious subject, you simply drill the small hole in the plug before you install it. Then deburr the hole as required. Yes it is a delicate operation but if you drill it with the plug in a vise and you are careful the worst that can happen is that you break the drill bit (no big deal). You could also take a die grinder and grind a very small hole in the plug this way you don't break any drill bits. Actually once your carbide burr breaks through just the littlest bit you can take your drill bit and finish the job. If the hole only ends up being .020/.025/.030" it doesn't matter as long as you don't make it any larger!! If it comes out too big (no big deal) get another plug, they are cheap!! You can get a lot of oil to shoot out of a .020" hole under 30/40 PSI.

Hey man, I just tried this last night with my son's engine. I drilled holes in the galley plugs, but had two issues:
1. I did not have any drill bits at .030". So I tried with the smallest drill bit that I had, which was 1/16" = .062". I think that it will be ok, as it still is a very small hole.... (That's what he said.... LOL!) I should be ok. as I am running a high volume pump with a high pressure spring (the hv pump and hp spring should have enough "@ss" to keep up with any losses - I hope) :sad1:
2. There it was easier to start the drill from the back of the plug as there was a little "raised circle" that was left on the part (almost like a burr, but not loose) and it helped me keep everything more on center than trying to use a punch and drill from the hex key side. ;)
However, when we tried to remove the "access" plug in the rear of the block to change the left rear lifter galley plug, the access plug was too tight. I didn't have the proper square tool to remove it. It was bigger than 1/4" drive, but smaller than 3/8" drive (probably a 5/16" drive???). :banghead:
So I went and found a cheap "made in china" 3/8" extension (3" long) and ground the head down to .311". Then heated the access plug with a propane torch (And propane accessories) but could not get the plug out. The cheap metal in the "china" extension just bent and twisted under the strain.... :banghead:
My son wanted to get his engine together, so we decided to wait and try it on the next engine that is going together. (We are already starting on prepping the block). :D
I will have to try an impact extension to get this one out in the future. :violent1:
