Nissan RD28 diesel conversion (swap)

[Dougal]

LOL You are a wise one. There are quite a few additional deaths for the Grenade than just melting pistons, such as cracked heads, turbos self destructing, rods breaking, etc.

There have also been quite a few Patrols with TD4.2 over 1 Million kms. If I remember right, a few have been documented on 4WD Action: one which traveled for years setting up the track for the Outback Challenge and another running as a pilot vehicle back and forth across Australia. I am sure if you used you favorite search engine you could find more.

Have you got any nice links for these? There are dozens of ways to word each search and each way produces a different result. It could take half a day to find the links you've previously found. A simple search doesn't come up with the goods.

FWIW, the ZD30 failures that I'm aware of were meltdowns. Collateral damage from a meltdown is the head, turbo etc. In one case I think the block and crank were able to be reused.
I've heard of rod problems in the YD25, primarily UK based problems but not the ZD30.

It was a only few posts ago you didn't know the ZD30's model code.

RD28 diesel engine economy

I think you mean the ZD30.
The one I've driven I was really impressed with. It's just the ones that decide the engine needs a whole lot of fuel that go bang.
With a boost and EGT gauge you'd be perfectly safe.

As for the Rd28. Fine as a car engine, but not suitable for a 4wd. How's the fuel economy in the merc?

Well, the Merc runs 14km/lt (39,6 mpg) at 100 km/h with the RD28. It is not that much but it is just 40% over the original gasoline engine. And, as diesel is another 30% cheaper here, you can make yr counts.
