Drill/Tap size for drilling the block

I am looking to see if anyone knows the drill/tap size for the oil drain. Let me know if you do.

23/32 drill bit

1/2 NPT tap

I am assuming I should start at a small size and work up?

You can borrow the drill & tap if you want...

Either size works it's the same. 23x2=46

And yes drill a small whole then work your way up.

Yes I would like to borrow those if you could.

Hey big ben,

i was just cleaning my garage and found my 23/32 drill bit & 1/2 NPT tap. i can bring them to the meet if you'd like. i have no problem of them being "community tools".

Let me know.

Sure that would be awesome! Yea that is coming up next weekend!

Yes both will work, but 23/32" = 46/64", not the same as 45/64".


Did you drill & tap the block yet Ben?

No I have not. I will be getting around to that shortly. Maybe next weekend.

Slacker. LOL just kidding. I have been lazy with my car as well. One of these days i am gonna take my i/c pipes off and bring a few valve covers and misc brackets to work and powder coat them.

Yea i have been lacking that thing called......motivation lately.

In this weather motivation is synonymous with warmth.

Yeah i agree, plus my shop is 20 min or so away from my house which doesnt help me get motivated. With that and the cold weather i dont like to do much besides game, surf the net, watch tv and drink. LOL
