Are the zd30s still failing or have most of the bad ones already failed and whats left may be more reliable?

It's much less common these days but it does still happen, I think I saw reports on here of 3 or 4 that failed last year. If you don't do the engine saver mods you are still at risk.

It's annoying when you spend your hard earnt money on a new vehicle and then have to spend more doing mods to it so that it does'nt grenade.Saying that I love my GU and I'm in the process of doing the NADS because overall they are a great vehicle.

It's a small price to pay to not have to be seen in a Toyota!

As Ynot said if you don't do the mods you could still be in trouble. I have a series 2 and have had no problems what so ever. When I bought it, it only had 27000 klm on the clock. Now has 167000 and all I've done is put a chip upgrade,catch can,thermo fan on top of intercooler,2 3/4 inch exhaust and that about it apart from running 5w-40 semi synthetic oil in it plus change it every 5000 klm regardless. I have plenty more to do but the finance dept is in poor shape so they have to wait. If you're shopping for one do plenty of homework on what/where it's been.

Its my understanding that the early gu failures was also caused by poor piston design. I believe that oil flow to the pistons was improved in a later improved design.

what about the old 2.8td i had 1 true not as much power as a 3lt or 4.2 but went every where with no trubel at all

Turbo failure is what got me not engine failure and that is not a cheap exercise either. Tony is there anything to do to get better turbo life?
