My IO-540 is somewhere between Calgary and Houston right now. Can't wait to get my hands on it.

While I'm waiting on it to show up, I'm building a dehydrator for it.

I'm looking for two measurements.

1) What is the ID of the oil filler tube?
2) What is the ID of the crankcase vent?

I'm going to get some rubber stopper for those holes to route the airlines through.

Thanks,
Phil

Filler ID is approximately 7/8".
Breather ID is approximately 3/4".
Good Luck,
Mahlon
