I'd also highly recommend replacing your tensioner and idler pulley(s). The Pre-98 Zetecs have two idlers with the 98+ Zetecs have only on idler.
I just replaced the entire timing system on my MTX with 183k on it. The 40mm idler had bad bearings and was starting to seize and melt. The 60mm idler's bearings were also going but what scared me was that it had cracks all around the plastic around the bearing. Could have been a catastrophic failure.
says it is an interference motor, and it was turned over quite a few times to try out different things before removing the timing belt cover to check it, possible that i am screwed?
You get a peice of .2" metal, turn the cams until you can slide it under them. Theres a notch in the bottom for the holder. The crank has a mark on it.
