Hello! Welcome to the site! Thanks for coming! I'm Ron Z. I'm here to provide as much info and insight as I can, to best answer your question.Yes- with the #1 piston at Top Dead Center, the crank mark should line up. If you have the crank mark aligned and #1 is not at the top, you're out of time- keep rotating the crank until #1 is at TDC and the mark on the crank is lined. Make sure you are using the correct mark on the crank. It should look like this:Then set the cams:Then install the belt.

That is the exact diagram I have, but the mark ends up on top instead of the bottom
I replaced the head gasket and the #1 piston, but 4 and 1 comes up together. I just went and lined the crankshaft pulley with the mark and still #1 is down. I have timed a lot of cars and never had this problem, that's why im here. Still when I line it up the mark is at the top and not even with the mark on the rear timing belt cover. The pulley only goes on one way that's why im confused.
Welcome to Justanswer ! my name is XXXXX XXXXX i will do my best to assist you with this problem
new expert here did you still need help ?
they time these engines at BDC as they time them where the # XXXXX piston is down on its way up for the compression stroke
if you align the bottom timing belt gear to the mark and the cams to the marks they should all align when the belt is on and # XXXXX piston should be all the way down
don't know why they did this but from what I heard with it being an interference engine that is how they had to time it with the marks
you can always get me through this post even after you rate us here at Justanswer with any follow up !
