Tapping out gallery plugs

Anyone have a "how to do it" rap on this for a Type 4?
It used to be on Jake's webiste but I can't find it anymore. I am helping a guy out here and can't find the procedure.

Drill into them. Thread a dent puller into them and yank them out. From their you just need to find the appropriate drill bit and tap. German Supply has a kit. Rinse the case over and over.

Colin seems to recommend just pulling the 'problem' ones by the flywheel. Should be simple enough.

I JBed mine, seems OK. Hey, isn't this procedure better left to a shop? Or am I just paranoid?

I think the Type 4 engines have been more prone to blasting those plugs out. I have seen issues with steel plugs that do not expand along with the case. I have seen some real butcher jobs.
If your plugs are secure and dry, JB Weld may perform an insurance function. Drilling and tapping is a good idea with an engine that has grenaded, it helps clear out the crap in the oil galleries. It is also a good idea with extremely high-mileage engines, so long as the quality of the work is beyond reproach.

I suppose this isn't a weekend job, is it? You are going to want to have the case apart if you are drilling threads, right? How could you keep the little bits of metal shavings from going inside the case?

You are correct.

You could JB weld them though.

Amazing stuff JB. Finicky though, it doesn't like the wrong application. Seems to do well unless it's stressed or load bearing.
Heck it's holding my brain together RIGHT NOW!

Pr'y work. I glued over the plastic cam bore pluge on my case with it because it's a press fit instead of the locking rib type like they used to be.
My old case had a 4" oil leaking crack under the flywheel that I fixed with JB and a layer of cloth sandwiched in there between layers of JB.
Stuff is tough.
