Crank pully and oil drain plug size confirmation

[Virto]

I'm going to work on getting the Z running again this weekend, but because the car sat for a year, I think I should probably pull the plugs and try to rotate the engine by hand. This will be a new experience for me.

The crank pulley bolt is 27mm (I know that 1 1/16th, thin walled will work). What size is the oil pan drain bolt? I don't have a lot of my old notes anymore - I think it was 22mm?

Think I could get by with the longest 27mm wrench I could find for turning over the engine? I'd prefer not to have to loosen or remove anything to get at the bolt.

One year is not much. But, with the plugs out, you could probably get it to turn with the average length ratchet handle.

Or, if you have room, you could put the transmission in to high gear and push the car to turn the engine.

22 seems big. Probably in the 14 to 17 range.

The irritating part is that I have all the torque info for the oil pan bolt, but not the size. It's not in the FSM or the manual, and searching isn't getting me too far. I have more looking to do, apparently.

Oooo OK, think I found it while looking in an unrelated thread about the coolant drain plugs.

Both the block drain plug and the oil drain plug are supposed to be 22mm. I'll go with that assumption until I end up with a socket that won't fit.

You got me. I just went out and checked a replacement plug I got at a hardware store and it was 22 mm.

I always use my big crescent wrench, so never really knew.

I confirm, 22mm is the wrench size you need for drain plug.

To turn the engine, you can also lift one rear wheel, put your car in 5th gear and turn the wheel. This is what service manual advices.

Otherwise, 27mm is the right size for crank pulley bolt.

It's an automatic - not sure if it'll work or if the Tq converter will cause a lockup. I'm also pretty sure the drums are rusted together anyway.
