Not only that but lets say it only jumped on one side, how is he going to know which side of the engine could potentially be damaged without knowing where the marks are before he takes it apart? It’s worth the time to get all facts to me. Besides, it’s only going to take a maximum of 4 engine rotations. Usually just 2. We’re not talking hours here. > > The camshaft(s) spins at HALF the speed of the crank, so for every full cam rotation you will have turned the engine over twice. :thumbup > > ILYA if you need anything holler. I agree 100%… but I would think it would still take more than 4 rotations to get the belt marks to lineup on all timing marks from the cam pulleys/crank pulley… While I know that for every 1 turn of the motor the cams pulley rotate twice… but the t-belt has a longer distance to travel… IDK im sick and fucked up on sudifed, I swear this makes sense… but it probably doesnt With the tensioner that loose thou and how he was descibing it cranking… it sounds like the cams/crank were just spinning inside the belt --- _[View the full topic](https://forums.speedlife.net/t/need-help-with-my-moms-subie/247509)._
