Took the belt off Pulled each wire like you said It did get slightly quieter but i cant narrow it down to what cylinder.

 

What oil are you running and how long has it been doing this? What filter?

Don't know what else to add. You're probably going to have to open it up to find out what's going on. Do you want to go that route or the boneyard motor?

 

found a engine from a 2004 jeep liberty it was a 4wd tho should still fit right? since i am only using the motor.?

 

Physically it will fit. Sometimes there are differences between sensors etc. Just use what you have on your current truck.

 

ok thanks

 

Any good junkyard will have an interchange manual so that whether it fits or not it's on them.

 

The engine that i found sounded like **** when i went to look at it what about a 3.7 from a dodge durango went to a few junk yards no luck.

 

Any 3.7 should fit. You might have to use some of your existing parts.
