That's interesting. :supz:

Any idea what size hole it is? Maybe 1/8"? Smaller? Bigger? I wouldn't want to drill too big and loose some oil pressure. :sad1: :oops:

It's only free if you don't break your drill bit drilling through the plug, which is not hard to do with a drill bit with that small of diameter.... LOL! :hmph: :banghead:


Too much lubrication won't hurt you as bad as not enough!! ;) :violent1:


Sorry, I just read and finally sunk in it's a .030" hole - much smaller than 1/8 (.125"). Very delicate drill bit....

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.
