Hi. I am in the middle of a timing belt job on my 2002 Montero Sport and need some help! Before I removed the old timing belt, i turned the crankshaft clockwise until its timing marks lined up. However, I didn't notice until after I removed the belt that the timing marks on the camshafts do not line up. In fact they are 180 degrees off. Does this make any sense? Is it possible I mistook the timing mark on the crankshaft?

Been ruminating on this while I wait for a new camshaft gear to ship..
I think when I still had the belt on, I should have turned the crankshaft one or more times. Given that the crankshaft gear is smaller than the camshaft gear, it seems plausible to me that another turn will get everything aligned. Sharing in case this is useful to anyone.

Keep in mind this is an interference fit engine. If you get them wrong and turn it over you'll do head damage. You only get one shot to get it right. Edward |

The crank rotates twice for every cam rotation, you're correct, you most likely needed to turn it over once more.
