Ok guys I have some questions Im hoping someone can answer. I have a 98 xj8 and it has the factory replacement engine with the steel liners in it. I spun a rod bearings and chewed up my crank pretty bad its junk. I went and found a used motor from other 98 but it has the factory nikasil liners. My questions are these:

1. Are you parts in the bottom end of both motors interchangeable? (rods, crank, pistons, ring)

2. I called jaguar about new bearings and they were asking for a bearing color code?? Is this just for certain years and the 98s have a certain color code or what??

3. When Jaguar put the replacement motor in my car with steel liners what did they do just take all parts off old motor press in steel liners and put everything back in bottom and top end?? So its just a Aj26 with steel liners?? Any help would be amazing thanks guys Jeremy

 

smitty- On number 2, bearings are fit to the tolerence of the machined surface. Most replacement bearings I have encountered are just set to the middle, which is one reason a used factory engine is many times preferable to a rebuild. I do not know if the color will still be on the back side of the bearing insert, but you could measure the rod and journal and find if which end of the fit you were on for each hole and then specify the fir.

 

Thanks for the reply sparkenzap. Can any one else help me with this questions? Thanks in advance
