Im sure some of this should be obvious and i *think* I know...but ...
For an m60 3.0l engine

1. Where is a suitable place to hand crank each cylinder to TDC?

The link http://www.geocities.com/dsmgrrrl/FAQs/leakdown.htm from Bruno's site says their was a slot in the drivers side wheel well. Is that true (or does this geocities site feature a random car?)

2. Instead of an air compressor, could i run compressed nitrogen?

I have no compressor, but i have abundant cheap access to nitrogen cylinders and can easily build a hose to go from a purging regulator to the quick connect of the leakdown tester.

3. Can i just hit the ground running or do i need to 'unhook' stuff?

I saw no mention of unplugging or disconnecting anything prior. No DME or Fuel pump relay disconnections (as a compression test calls for)?


Thanks in advance,
Terran
