hey guys i just put in my ctr cam and i went to start the car and it made a nasty ping sound. so i popped the vc off again and the intake timing was a little off, so i realighned it and i think its good now, heres how its setup now. one thing i was concerned about was that the top of the timing belt between the cam gears loosens and tightens every half turn of the crank... wasnt sure if that was ok.


You have a subborn tensioner. I explained this to another member earlier today.
Make sure everythings lined up correctly at TDC. Have the tensioner halfway tightened down (enough that the belt is tight but also enough that you could tighten more). Rotate the engine (by hand) 90degrees then tighten the tensioner down the rest of the way. Rotate the engine 5 or 6 times and see if it still jumps. If it still does do it again. If by chance it still jumps after that you might need to look into getting a new belt or a new tensioner.
Edit: Your crank isnt at TDC. See that line thats more up the crank, thats your TDC mark (the line thats past the 3)

yeah/\ when initially timing the motor you wanna line up the white line thats all by itself then make sure ur cam gears have "up" in the up direction and the lines are lining up, when lining up the cam gears i find it helpful to look at all 4 lines not just the 2 inner ones, they can be decieving. maybe if its ur first time id suggest using some sort of straight edge. Once you do it right once it'd be really simple the next times u have to

Yep, you are more along the lines of 16 degrees BTDC.
The easiest way I have found for the initial alignment of the cams is use both lines (inner and outer as was stated above) and if you don't have a straight edge, line them up so that both are parralell (sp) to the surface of the head. That's dead on.
Good luck and I hope you didn't bend a valve or two when you cranked it over like that.
