Hey guys hope everyone is doing well. First time user on this forum and I’m hoping someone can give me a helping hand.

I have a 2000 Jeep Cherokee Sport XJ with a 4.0. I recently got the car running with a rebuilt motor. However the truck keeps dying on me. So far I’ve narrowed it down to the cam synchronizer because the gear is chewed up. I’ve tried 3 different brands and so far no luck.

I set the timing on TDC compression stroke, sensor facing bell-housing, and she runs strong for 30 mins but after that the truck does not want to run. I’ll attack a pic of the sensor.

Any info on what to check or look at is extremely welcome and I hope I can get the issue resolved.

This is the gear after it dies

 

Im sorry everyone but my cam was the issue. Cam gear was extremally damaged.

 

glad ya figured it out.

 

Might also be helful for the thread to explain HOW you found out..

 

When I took a closer look I realized the cam was the issue.

 

All that metal is now in your pan, or somewhere in your oil system
