Hi Jared,

Welcome to the forums. I moved your post into a new thread.

What engine(s) are we talking about here?

 

thanx its a 4.7 in a 2002 dakota 4 door

 

i found a motor its a 2000 4.7 but i see people sayin it wont work in my 02?

 

i guess what i want know is will the 2000 motor fit in my 02 without changing anything or do you think im better off putting the chain back on my orignal motor and giving it a try but i got a feelin it bent valves from what i see these are a interferance motor? thanx for you help

 

The problem with a 2000 motor and your 2002 may be the tone wheels. There's two, one on the crank and one on the camshaft. They are different and not compatible. The change was made in late '02.

Take a look at your PCM on the passenger side inner fender. How many connectors are on it? If you have 3, you are running the JTEC PCM and it will work. If you have 4 plugs, it's NGK, and you'd have to swap out the tone rings. In order to do so the crankshaft has to come out.

 

my regestratin says 02 but on the door manafacture date is 11month of 01 i have allread check the computer it is a 3 plug

 

Then it should work just fine.

Just replacing the timing chains is a major challenge. If you can get this motor for a good price you should be ahead of the game.

 

thanx alot for you help i think i will still take my orignal motor apart and see if it is toast if not i might fix it for spare thanx for all your help
