you can use their holding device, but its pointless because the cam sprocket for the exhaust will spin anyways. The holding device is just good for the intake at TDC and the exhaust just takes a little time but less than 30 min if uve done it before. I have to try this pin idea, ive never seen it done. My method worked and the car runs like new.

Looks like the belt is hitting something in my case. Ill see next week after my last exam.

Good luck guys.
