I did my own leakdown test on my engine prior to rebuild. I ran the engine up to proper operating temp (by driving it), then pulled into my garage and did the test with the engine "warm." Did not run it between testing cylinders and yes the spark plugs were hot, but its manageble.

I also performed/witnessed leakdown testing on a cold motor, fresh zero hour rebuild with replated cylinders, new pistons using total seal rings. The leakdown was <5% on that one cold.
