I have an engine from a 93 cherokee and was wondering if I can use the parts from that engine to clean and replace the parts in my 89 engine with those? Please help.

 

Many things just won't interchange easily. The 89 is a Renix era engine while the 93 is a H.O. engine. Intake and exhaust are different. Many sensors are also different. The ignition is different. I think the water pump is the same.
As to cleaning up do you mean clean a 93 part to replace the 89 part? If you do you see that most things will not work that way. I think even the valvecover is different b/c the H.O. had a pcv and the Renix only had a static vent line.
Sorry!

Thanks. It was worth asking.

 

That's what this forum is for. Any Renix questions are easy for me but get up towards the last years and they are like working on a space shuttle. I have no idea what half that stuff even is for.
