Brain fart / Help needed with timing chain
Hi,
Today I took on me to replace my chain cover gasket, so I pulled the cover off then the chain tensioner. While the oil was dripping I decided to try to rotate the harmonic balancer to see how it works since I plan on doing the valve adjustement.
While doing that I noticed that the chain was jumping and not turning and then I realized that I had turned the harmonic balancer a few time but the chain hadn't move so now I have a feeling that my timing is all screwed up so I would like to know if there is an easy way to make sure that the timing is good.
Thanks in advance for your help.

I do not understand how the chain can jump time just from pulling the cover. Did you loosen anything else? Possibly did you turn the engine backwards and collapse the tensioner?
Timing a 911 motor is more complicated than simply lining up marks, but still no big deal. The top valve cover on #1 cylinder needs to come off, and you need a dial indicator on the #1 intake to measure the valve motion as the timing marks come up on the crank.
