I'm rebuilding my motor in my 2001 xj. I was wondering if the internal components differ from an older renix motor. I know the intake manifold and fuel injection is different. It hard to find everything for 99,01 would I be ok to buy bearings and gaskets for the older motor?

 

The internal stuff you will have to get it based on what year the engine is, I would assume.

 

Heads different... check part numbers on Autozone.com between the new and old of what u want to buy... if there the same then the parts the same...

 

Ok thanks guys
