Re: My exhaust cam doesn't have a timing mark (and I think I'm off a tooth)

If it is off time it will code the ECM-644 ? can pop the Check engine light on after the first restart, so if you dont have that, its timed right. The marks are there but they are really small and easily missed. That Dayco timing belt is not known for its consistency vs the Conti Tech belts, its wo...

I marked the cam sprockets and crank pulley, and aligned the new belt with the painted marks. I rotated it by hand with no issues. I checked everything by lining it up with the...

I pulled it out and cleaned it (job wasn't as bad as I thought) and reinstalled. When I started the car it was in limp...
