well i pulled my motor down,found a hole in number3 piston and a crack in number 4.Head also had cracks.Rebuilt it put it back in and off we went,did 15 kliks when the fire went out-damn!!!Towed it
home again and further investigation revealed a sump full of water and when its winding over its pumping oil out of the dipstick.I am at the end of my tether over all this.Anyone got any ideas????

Know how you must feel. Don't know much about you motor but I have on odd occasions had head gaskets (especially non genuine) that are slightly different with their water jacket holes which can let water into the sump. I assume you had the head repaired/replaced & checked before putting it on. Does the ZD30 have wet sleeves? What I have done in the past is to drop the sump, let the drips stop, fill the motor with water & see if you can find where it is entering the sump. IE from the oil drain galleries from the top of the motor/around the pistons ect.
from what you say I would think that it won't be hard to find.
Someone who knows these motors can probably tell you more.
Regards Mike.

AAAaaaaarrrrggghhhh!!!!
Mate I really feel for you. Just going through rebuilding
mine at present. Pistons 1 & 4 cracked; 2 burnt a hole; 3 OK. Seems obvious this is a problem with piston MATERIAL. Maybe Nissan had a bad batch. NNNoooooo !! Not Nissan.
Did you replace the O ring and gasket at the front of the head?
Come to think of it, I remembered the O ring but have some gaskets left over. Have to
check mine now. :-(

Buggeeeeerr !!
Guess what I forgot?
Spent the day removing the head and putting that 'U' shaped gasket between the head and the timing gear housing. You can
check if it installed by looking at the off-side (that's the driver side) of the engine behind the timing gear housing. You should see a metal gasket hooked over a locating pin. I've now got a piccy of it if anybody is interested.
Still kicking myself around
the block.
One good thing, somebody will learn from my mistakes.
At least it gave me an opportunity to take some photos of the new pistons which I had forgotten to do on the initial build.

Hi 4wdr,
As a current owner of a 4.2TD GU, I am glad I never bought one of these grenades. Sadly, the whole issue rests with Nissan, who seem to be shy of really taking responsibility. For this reason, I'd be very wary of buying another Nissan.
Let's face it, most models, whatever brand, have some teething or design problems in their life, but the real
test is whether the manufacturer has the balls to own the problem and fix it, and Nissan, (along with a couple of other manufacturers I won't name, lest I be accused of flaming) in my opinion have let their customers down badly.
People will say that the percentage of engine failures is quite low, but for the poor unfortunates who have to bear the brunt of these failures, it leaves a very bad taste in the mouth and a larger hole in their pocket.
Sorry I can't help further
Gerry

Read my comments above ...
IMHO 4wdr rebuilt engine has nothing to do with Nissan.
I'm a ZD30 owner (in fact I have TWO - 2003 and 2005) and am very happy with it as a vehicle. I have never had one problem with the 2003 and its done 150K. Unfortunately I bought a time bomb from a mechanic and had only done 1800kms when bang. Umh ??
I'll rebuild
mine and keep it.

Hi Nick
only 4wdr can really answer that.
as I said in my posts, I think
mine is due to bad piston material.

A rebuilt engine with low kilometres in a "Lendendary Patrol" has everything to do with Nissan. As mentioned above, if the failures are few then Nissan should fix them. Fact is they are not few and they will keep coming and hopefully there will be more publicity, if a major media organisation has the balls to take them on and that will be the end of Nissan.

I'm not disputing the debate with a new ZD30 engine.
What we are (or at least I am) talking about here is the fact that 4wdr is rebuilding his ZD30 engine himself - now THAT has failed.
I can't see how that has anything to do with Nissan.

4wdr,
I have heard of a bloke doing a 4.2 transplant. i think he is on patrol.com. it can be done, and there are minimal engineering issues to deal with (in the ACT its like that anyway) as the modle you have came out with a 4.2, thus not needing engineering.
let me know how you go, because if my zd30 goes, thats what is going in
mine.

It really is time for a class action on this one.
In my view there are a couple of contributing factors, but mostly come back to too much heat and cycling between high combustion temperatures and lower temperatures. A failed MAF can contribute in some circumstances, but basically I believe you are looking at an engine management system and some ancillaries that allow combustion temperatures to get too high, and if towing or doing lots of highway work, the engine management system allows cycling up and down in temperature that eventually results in failure.
Nissan claim to have fixed it and maybe they have but I've measure 575 deg C after the turbo on a brand new Nissan patrol with 5000k on the clock and that worries me.
Everyone who has failed engines should get together, find a good lawer and try for a class action. That is my personal view.

David
I'm afraid my experience with lawyers in the past has not been good. Even when I know I am in the right, and they also do, they say if you go to court it could cost you $20K+. You have to make a "Commercial Decision". I have a couple of times - each costing me around $10K to make the problem go away.
My wife keeps saying that I could not handle the stress - just walk away from it. I think she is right.
Our local Federal MP wrote a letter to the CEO of Nissan Australia on behalf of all the ZD30 owners in this blown-up boat after I contacted him last year. The response after two months is absolutely zilch, nothing. Such arrogance by Nissan CEO IMHO.
Would like to meet up with you when you are available. PM me.

That's why I sugget a class action - cost sharing, evidence sharing, better chance of success.
