Those images are not of our 4.0 liter engine.
What are the details of your rig?
Engine, tranny, tire size,year,mileage?

 

 

sorry basic seem to even escape me

its a 1999 cherokee jeep orvis 2.5litre TD manual
im in the uk, I'm its 11th owner.. !!
we thought the log book said 1 previous owner

 

We never had that engine on this side of the pond. Hopefully, someone with experience with teh 2.5 will chime in.
