drilling an oiling hole into unstuffed dmp crank?

Can you do it? Should I do it?

What drill bit? How big? Pros/Cons

The stuffed dmp has an oiling hole. I probably would have bought it had I known that.

Discuss...

2 or 2.5mm? Do it. smooth out the entry side of hole to relieve stress

Re: drilling an oiling hole into unstuffed dmp cra

i got a dmp stuffed crank and took out the stuffing....suuper easy. stuff falls right out.

Re: drilling an oiling hole into unstuffed dmp cra

How exactly did you pop out the stuffing? I doubt it simply fell out. Lol.

Re: drilling an oiling hole into unstuffed dmp cra

Drilled out the stuffing holes and used a screwdriver and some heat.

Re: drilling an oiling hole into unstuffed dmp cra

Should it go in a certain place? Same as place as the hole on the stock e50?

Does that matter?

Just read this post where zach and shaw speak the truth on this subject:

Works every time.

It will also help if you radius the inner opening of the oil hole after you drill it.

Do you need the hole in the end of the con-rod if the Piston has the oiling holes with a roller bearing crank?

Re: drilling an oiling hole into unstuffed dmp cra

it wouldn't hurt. when i get my dmp unstuffed, im gonna drill small wristpin holes on my 80MK piston, a small hole in the end of the conrod and take out the new dmp rollerbearing and go to a bearing shop and get a decent replacement just in case. bearing shop rollerbearings have got to be way better built.

im mean im not paranoid or anything. haha.

When you do this, get a hold of me and I'll come down so that we can do mine at the same time... I don't trust me to drill a straight hole... Got a drill press. I really don't want my brand new Gila to get fucked in any way... :) I'm also paranoid.

I've got a Gila with the good piston with oiling holes, DMP unstuffed combo.
