I have a 2004 disco. Does anyone know of a good mechanic in Colorado springs that can help as I believe I have a slip sleeve.

 

Any thoughts on swapping a range rover 2002 4.6 in a 2004 disco

 

I did it on my dads 03'.

The thinking is that from 97-02 Land Rover was grading the blocks. Blocks marked with a red paint dab were the highest quality(thickest cylinder walls) and were used for the 4.6 motors. By 03/04 they were only making 4.6 motors with these blocks so they no longer used the grading system, hence all the 4.6 failures on the disco 2 models.

So,I think it's good idea. You need to swap the flywheel and all the the accessory brackets(I think the power steering pump is the only different accessory). Besides that it's plug and play. Do the head gaskets, timing chain, and oil pump service while the motor is out at a minimum.
