Beating a Dead Horse
So i pulled apart my Jeep engine again last night. Getting to be quite a pro at it. I figured out what the knocking was. A screw that hold the first pully to the harmonic balancer was poking through the back side of the harmonic balancer and manged to chip away at part of the timing cover. Nuts!
I tried to use the wifes thumb to help me determine pressure in the #1 cylinder. I think she needs to go back in for calibration, it didn't work out too well.
While scratching my head and wondering why this isn't simpler, I made an observation. The Harmonic balancer has the tic mark that you pick up with the timing gun (strobe light). The timing gun fires with every firing of the #1 cylinder, which allows you to see this tick mark. I thought to myself, well how do you know you go the harmonic balancer on there correctly in the first place, in order to have the tick mark collaberatively lined up with the firing of the #1 cylinder. Well, the harmonic balancer is keyed into position on the crankshaft, so therefore, as long as the crankshaft is installed correctly, then the tick mark on the harmonic balancer will always have a direct relation to the orientation of the #1 piston.
What i can't remember though, is how many revolutions of the crankshaft there are, to the # of times the distributor rotates through 360 degrees. Is it 2 rotations of the crankshaft for every full rotation of the distributor? I think so. So really by using the any of the methods listed here, you still have a 50/50 chance of getting the #1 cylinder TDC the first shot.
Please provide criticsm, comments, etc...
