I’d guess $20,000 plus for the Cummins if a shop does it. On your 4.0, unless you slipped a liner which would be odd on a 4.0, they do pretty well with an upper end rebuild. If all it is doing is leaking coolant that is probably all it needs. You probably don’t absolutely need a valve job but it is not much extra money since the heads will already be off. That is what I would do.Yeah I’m asking because I got my disco for $3k not much rust just some on the body near the alpine seals. But believe the head gasket is blown. Seeing radiator fluid leak from the gasket. Wondering if I should replace the head gasket or look at a full rebuild because I plan to do a year long trip living in the disco. How much would a Cummins swap run with a 6 speed?
