Hello Jag World. I'm a relative new Jag Newbee. I have a 2000 XJ8 that recently skipped its timing and bent a few valves. I have found an engine from a 1998 to trans plant for $500. The general consensus is that this is the most practical and cost effective way to proceed. My concern is whether it is compatible. Does anyone out there know what I need to look for to ensure that I have an acceptable replacement? VIN #'s etc?

Cheers

Welcome here!

You'd be trying to fit an AJ26 into an AJ27 system... It is - as it seems - possible but requires a fair bit of work. Different sensors, injectors, etc.

 

It is EASIER to put an AJ27 engine in an AJ26 car. There is no hole for the Bank 1 CMPS and there is NO oil temp sensor hole in the AJ26.

The VVTs are different etc.etc.etc........

EASIEST way is to install a 'like' engine from 1999> XK/XJ 4.0 Normally Aspirated.

Thanks to Bob and Daim. I was afraid that this would be the case. What years would you recommend that I look for. I've noticed that this motor seems to have three or four evolutions.

You want an engine made after August 2000, which would not have Nikasil liners. That means a 2001 model or later. Some early 2001 models were made before Aug 2000, so you have to check the engine number on 2001 models. 2002 are all good.

 

I think you mean 2001, August 13, Midnight onward (From Engine (0108130000))
