I’m ready to do a leak down test. I have the harmonic balancer timing mark lined up at 0 and can see that the #1 piston is as close as it could be to the bottom of the spark plug or underside of the head. Couple of questions. The instructions say to do on a warm engine. Everything else I’ve read and heard say cold engine. Firing order I believe is 1-8-4-3-6-5-7-2. How much do I rotate the crank to get TDC on the next cylinder to test?
