Hello,

My name is Jan-Willem ter Steege from the Netherlands and i'm new here on the forum.
I'm writing this on behalf of my father.
He has been driving a Patrol for over 35 years but the last 8 years or so a 2005 ZD30 DI and thats when the problems started.

In 500.000 km (312.500 Miles) he has blown up 5 engines (1 was replaced with a new crate engine from Nissan and the others were used engines).
All the problems were headgaskets and melted or broken pistons.
He is no speed devil and drives carefully but he tows 3.5 metric tons (7716Lbs) every day.
Odd thing is that they all broke at idle or near idle without any load on them.

I read on this forum that these problems may be caused by to bad boost management from the ECU and the EGR valve.
Is this easy to fix by myself (i have a technical background) or do a need a specialist for this?
I dont think there is anyone in the Netherlands who does dis kind of work.

Cant the ZD30 handle load anymore or will the 'NADS' fixes cure this issue?

Any help and advice would be appreciated.

Kind regards,

Jan-Willem ter Steege

The problem is that the ZD30 isn't supposed to tow 3500kg. It will pull it but the internal temperatures would be very very high on a stock engine.

Anyway to solve those high internal temperatures? On the old 2.8 TD my father used to get to 500.000 km on one engine, always towing 3500kg.

Go to the DI archives and read two articles, 'so you bought a zd30' (link in my signature for that one) and also 'ZD30 Engine, What makes a grenade a grenade', this explains many things, this forum has more experience with the grenade factor than any other group, actually been through it myself in 2006 with my 2000 ZD30DI which I have owned since new and did a hell of a lot of research into the issue so it would never happen again.

Gold Coast patrols and mechanical have come up with a zd30 engine fix solution. CLICK THE LINK

It's good to see them doing something for the ZD Patrols but to say THEY have come up with a fix or solution is very misleading. Everything on their list has been in this forum and modern diesel forums and workshops for many years now. They are just another shop putting together is list for the punter who knows nothing.

Absobloodylutely, the knowledge and fixes have been in here for a very long time, no one needs to go past this forum for any further info, there are hundreds of us with hard driven ZD30's as evidence. Most of the knowledge places like this have is taken from this forum.

Thank you for the information! Did some reading and watched some of your videos. Think there are a few steps i have to take.

1: Rebuilding the engine. I have a good engine shop near me specialized in diesels.

2: Fitting a EGT and boost gauge and see what the engines does.

3: Blocking the EGR.

4: Dawes valve and needle valve or Tillix kit.

5: ProVent 200 catch can.

6: ECU remap at Gold Coast Patrols.

7: Maybe a better intercooler?

8: Maybe a 3" exhaust?


Anything i am missing here?

Thanks again

Good start, look in my signature for a link to Harley, Performance Tech, Harley is a supporter of our forum events and also does or can advise on mail order remaps, making contact and asking a question costs you nothing. Harley has been doing them for many years and mine was one of the early ones.

I've send Performance Tech a message. Thank you for the help. Hope you wont mind me picking your brain a bit.

  • Any good sources for engine parts?
  • Anyone used the ebay intercoolers or are they a no no?
-Tillix or Dawes?
-What is a save EGT when under load while towing?

Thanks

Hi Jan
1. Either Dawes or Tillix, both work on the same principle and both work well.
2. EGT. As said in the articles for a DI we use 550c as a maximum, you can go a little higher but definitely don't let it hang there, the CRD can use 650c. I have seen a DI in cruise control (after an EGT gauge was fitted) at 100k creep to over 700c very quickly and that can be deadly over time, without a gauge you just don't know it is happening and the engine doesn't complain until the final act.
3. There are some reasonable ebay intercoolers out there, it depends what you want from your car and how much you wish to spend, I know guys with HPD (and HPD copies) who have them working OK.
4. Sources for parts. this can be tricky, what particular parts are you after?

I'm really wondering what the EGT was on my father Patrol when towing 3500kg at 80kph....
Also really weird these fixes were not advised by our 4x4 specialist that does the maintenance, probably because blocking your EGR is illegal.

Probably will only change the intercooler is its still running hot after all the other fixes.

Well we will be needing parts to rebuild the engine. For sure new pistons, liners, crankshaft bearings, rod bearins.
But i will check when we get in there because i dont want any half measures while we have it apart. Dont know how the cylinderhead is but wont be saving money on that either.

We have been working on these fixes for many years, this forum knows more about Grenades than any other 10 groups or business's. EGR blocking is also illegal here so it is not an 'Heavily Advertised' fix but it is only part of the problem, still a big part though.
Definitely do not short change the head, this is where we often hear of repeat failures because someone has done a quick rebuild to sell the vehicle.
I'll put you in touch with a guy who has just rebuilt his, he may have some suggestions, mine was rebuilt way back in 2006. There are some good sellers on ebay but you need to do some homework.

Hi Jan, I'm currently rebuilding my ZD30 Di and the complete rebuild kit I purchased was from SMS Diesel Spares.
AMC branded heads seem to be the high quality aftermarket heads here in Australia. Contact SMS Diesel Spares, they're extremely helpful. Have a look at my rebuild thread post #62 I have some pictures of the kit and some side by side pictures of the new and old heads. Cracked head ZD30DI

@jwtersteege as everyone above commented, issues with Di's "grenading" is well documented here, but I do think it is worth pointing out that there was never a ZD30 engined Patrol with a towing capacity of 3,500kg. The highest, I believe was 3,200kg with a MANUAL transmission. Towing 3,500kg is certainly giving the poor ZD a workout, so keep that in mind post-rebuild. ;)

Absobloodylutely, especially if there is no EGT gauge to see what is happening and when to back off, as I said to him I've seen a vehicle go to over 700c very quickly, it doesn't take much if the vehicle doesn't have NADS and that was without towing.

Thank you for the reply. AMC heads are made in Spain so it would be quite counter productieve to ship it to Australia and then ship it back to Europe. So i think i wil look for a supplier overhere. I will contact SMS Diesel Spares for the rest of the parts i need.

If my head isn't cracked, is it save to reuse? Or should it always be replaced?

Thanks for the info

I totally get where you're coming from. The problem is that here in the Netherlands for this kind of work there are very few alternatives... And the alternatives that we got also have a lot of problems. Nissan Patrols always treated us good, especially in the early days. I would like to give this one another shot. Lets see how reliable we can get this one.

What temps are they running post NADS?
