I started to post this in "Engine and Driveline", but I think maybe it belongs here. I'd like to buy the tools to chase the thread on the hole where the oil sensor screws into the block on the 250/292. I've always thought it was 1/16 pipe, but that doesn't seem to exist, and I haven't got my Machinist handbook to verify.
