XJ diesel engine swap

Hi all.
My name is Evert and I'm from Australia. I just bought an XJ Cherokee 2.5 liter turbo diesel. Unfortunatly 10 km after the purchase was done and I drove away I blew the cylinder head gasket. I now have two options, get the gasket fixed for a few thousand dollars or get a new engine.
Has anyone ever put a new diesel engine in an XJ? I currently have a VM Motori turbodiesel I4 425 OHC in it (as it was sold in Australia)
Does anybody have some experience with putting in a VM Motori turbodiesel I4 R425 DOHC or a VM Motori turbodiesel I4 R428 DOHC? These are the engines from later Jeeps.

Welcome, but there were very few diesels in the US. Hopefully someone from Europe can help. Another resource for you may be search for Go Jeep XJ he is in Australia.
 
Yea we never really had a chance with those engines States side. Darn emissions controls.

If you decide you want to swap in a 4.0 gasser, this forum is probably your best resource. However a lot of us guys on here love diesels, so I would recommend keeping it.

What are the chances you could change the head gasket yourself?
 
Have a search on some of the UK forums, PM me if you need some help finding them or getting answers. I'm a 4.0 driver so can't answer your questions but there is plenty of diesel tech available on the club sites over here in the UK.

would you want to sale your 2.5D?
 
any of the earlier ones are going to be the easiest. the later models (late 90s and up) all have seem to gone to electronically controlled injectors. your best bet is one that still uses a mechanical fuel control (for the injectors). less wiring, no computers and a lot easier.
im jealous you guys get all the diesels. lookin thru your list of possibilties i cant believe all the cars that have diesels. we got the shaft in US
 
In the U.S.:

Renault 2.1L 4cyl. Turbo Diesel - 85 hp @ 3750 rpm, 132 ft lb @ 2750 rpm - used in 85-87

Pretty much a boat anchor that was under powered and loved to blow head gaskets.

Parts availability is extremely limited, as in few commonalities with Renault cars, and if you can find parts get ready to re-finance the farm or give up your first born child.

Seen some posts of guys running Nissan diesels in XJs, don't have any specifics for you.
 
I would say just do the head gasket. I wish I could get ahold of an XJ with the VM diesel :mad: Head gaskets are usually a pretty simple operation.
 
Yeah probably going to pull the head off and send it away for crack testing. Bad thing is i don't know how long the engine has been running with this leak so I don't know how bad it all is. I'm still looking for a new engine, but we'll see how bad it is as soon as i take the heads off.....
 
The VM diesel has a fairly poor record in the UK, especially pre-97 ones. The symptoms of head gasket failure can actually indicate the separate heads becoming porous and needing replacement.
 
isnt the cummins 4 cyl a monster compared to the VM? Thats a good thing!
 
i like to swap a Mercedes 3.0 v6 diesel in a XJ out of a Sprinter... They are lighter weight than the B4t or darn near the same weight.
