2001 Dakota 4.7 Timing ?
Picked up a 2001 Dakota with the 4.7 magnum engine in it. Was told that the vehicle needs a timing chain. Bought it cheap and it isn't running. No codes thrown and it cranks over but no start.
I am hoping that there is no damage to the valves if the timing jumped. Any suggestions where to start ?
Thanks

I plan on doing that. Just want to make sure the valves didn't get slammed by the pistons and are not bent. I would assume the only way to tell if they are bent would be to pull the heads.

The couple degrees is not accurate even if it was an interference engine. Your timing will have some degree of natural slop in it depending on RPM and wear. If they made them that tight the engine would be dead the first time you gave it gas. I'm seeing mixed results online but I can say with about 75% certainty that it is not an interference engine. As for your actual issue. Are you certain its timing? The engine cranking but not starting is usually a fueling/spark or crank sensor issue. Is there a reason you suspect timing?

I’m going to pull the valve covers and see what the timing chain looks like and if it is out of time. Then go from there. I don’t want to crank the engine a bunch for fear if it is out of time, I don’t want to bend the valves.
