Drill size on TF Oil fill?

[PhLoBuS]

I have TF Valve Covers and I received my Oil Fill kit, now what size drill/drill bit do I need for it?

I will have to go home and find out but I used one of the drill bits made for wood. It was a lot cheaper than a 1 inch+ drill bit. I think it is 1 1/8th but don't quote me on that yet.

sounds right, 1-1\8" . I used a hole saw at work.

I did mine. I believe it was 1-1/8th. Was a bitch to do though. I had to keep putting clay under it and making sure it would not hit any of the rockers.

Yeah I plan on taking off the valve covers then doing it
