Rebuild of 2.5TD

Attached is my first draft of my checklist for removing and rebuilding my 2.5 TD.

I will begin this in the spring.

Any suggestions are appreciated.

I will post pictures and hopefully video the entire process and post it here.

I think this is a labor of "love" or maybe just typical Land Rover insanity

I think the only suggestion I would have is replace it with another engine - and don't rebuild.

Of course this is keyboard advice! I have never even driven a 2.5TD on the road, its different off as you don't want speed (but do need torque - which it lacks too - in comparison to others)....and from what I know these engines are largely boat anchors...

I would be interested to know why you chose to rebuild vs replace with a better diesel 200/300Tdi or other and/or GM V8 conversion.

The one thing I would plan for is having the hot spots in the head more permanently affixed than what Rover did. Hot spots drop out of these heads and destroy the engine.

Why rebuild a 2.5 TD

As they say "your mileage may vary" but here are my reasons for rebuilding:

1. This is a toy truck. I just use it for local fun.
2. The engine runs fine except for the numerous oil leaks and the obvious pressure build up.
3. The challenge of rebuilding and engine. Your never too old to learn
4. Costs - I calculated that to get a used but not rebuilt 200 TDI for my truck would be around $6500, not including my labor to install it. I've estimated a cost of $2000 for the rebuild of the 2.5 TD, doing it myself.
5. I take care of my vehicles with constant preventive maintenance so the 2.5 TD rebuilt should last awhile.
6. I don't want to modify the truck to accommodate another engine e.g. 300TDI or V8

These are my personal reasons. Of course I may find upon dismantling the engine that it has so many issues that ti should end it's life as a boat anchor but I'm optimistic given that it doesn't exhibit any obvious major faults.

Doug, thanks. Some of the books refer to the hot spots and how to examine and repair them. I will add that to my check list.

They,the manuals, say cracks are acceptable. I'd suggest otherwise as once the crack grows the hot spot falls out and ruins the head and piston. I'd have the machine shop pin the hot spots into the head so they can't drop.
The blow by issues causing your leaks are what that engine is known for and many self imploded by running away on their own oil vapor blow by. I wish you the best with your project, like most things Rover, the original design can be improved on.

Doug, my brother had his 1954 MG engine "pinned' and it worked out fine. He also had some parts like the crank shaft magnafluxed. they discovered some imperceptible cracks and he decided to replace thee crank. the crank cost $2500!

As I mentioned, if I have to do too many fixes on the engine that I didn't expect I may have to throw in the towel on the rebuild. Wish I could diagnose these problems without pulling and disassembling the engine.

why don't you buy one from one of the guys that has replaced theirs? That way you rebuild and drive at the same time - then swap put, then rebuild the other - now you have a spare

Johan was offering a 19j for free a couple weeks ago.

Thanks guys, Great idea. I e-mailed Johan.

My only concern of getting another engine is what consideration it is in. But if its free then less risk except getting it to my place.
