Rebuilt D4Ds....do they perform as well?

Hey Guys,

for those who have gone through the pain of an engine rebuild, (and I hope you don't mind me asking) has the car performed as well and is the engine more fragile going forward? I'm looking at buying an 07 KDJ120 which has just had a rebuild after injector failure / holed piston (water in fuel) and thought people here might have real world experience. It is under warranty but this is not transferrable.

Cheers
Ed

It all depends on the skill and level of care of the mechanic that did the rebuild.. Speaking as a diesel mechanic myself

It certainly is a bit of a lottery, how many km has the engine done since the rebuild?

It's barely done 400km, so it hasn't had the 1000km service after the rebuild. It was done at a reputable shop but yeah, I wasn't sure if it's a new lease on life and gives the engine another couple of hundred km or if it might go pop again if they've made a mistake.

Don't buy it unless you can verify that the rebuild was done properly. Ask for the parts list and who did the rebuild. How many D4D engines has that mechanic rebuilt? Were the injectors replaced, and what brand?

Take it to a diesel mechanic for a thorough inspection.

Needs a techstream inspection after sitting overnight.

Needs a proper compression test.

Needs to have a usable guarantee or a cheap buy price.
