How should the timing marks line up on a 1986 Plymouth Laser (2.2 litre turbo)?
Thanks

Use the center of the rounded top of the valve cover directly behind the cam gear as your 12 o’clock position to locate the cam gear.
After you think you have it timed correctly; rotate the engine in a clockwise direction at least two full turns at the crankshaft. Then check that it is still aligned properly and that the belt is tight but not to tight or it’ll howl and fail prematurely.
Rule of thumb for belt tension is that if you can just twist the belt 90 degrees at the widest gap between gears; using a fair amount of force by hand, your tight enough. In this case the widest gap is between the cam gear and the intermediate gear.
Last thing I can think of about this job; when you rotate the belt tensioner pulley against the belt; rotate it in a counter clockwise direction. I’m not sure why they want you to do this it seems to work in either directions. All I can think of is they want that pulley as close to the crank gear as possible.
