How Do I Find TDC to Adjust Valves
I've done this before, but this time I'm having trouble verifying that I have TDC on the Number one cylinder. There is no Z1 mark on my pulley, so I'm not sure the best way to find TDC. On my motorcyeles, I just take out the number one spark plug, put my thumb over the hole, and turn the engine until I feel the compression, then look for the appropriate timing line. I thought I was ok today with the Porsche, but when I got to number two cylinder (one and six seemed to go fine) the exhaust valve was tight, and when i tried to loosen it, I could never get it loose enough to turn the pushrod with my finger. This is an '87 911 BTW, and the car was running fine so I think I'm doing something wrong. Thanks in advance,
