The problem with compression testing without a starter motor will be getting the engine to turn over fast enough to get a semi accurate reading. As stated above, A leakdown test is best. It would be possible (maybe) to turn the engine fast enough to test compression by using a impact wrench on the front pulley nut. I would mark the nut to make sure you are not tightening it more and pull all the plugs out of the engine to minimize the load.
Is there a way to test compression while the motor is out of the car?

the yellow is inside the head, it doesnt flake off. the oil is dark as a truckers coffee. the motor is at the shop where im doing the swap. but i want to test the engine before i put it into the car.

If it's at a shop, they should have a leak down tester/air compressor. Do that. /thread.1974.5 Jensen Healey : 2003 330i/5Comment
