    My very last 2 have gone off just this week, one at the Sunshine Coast meetup and the absolute last one I sent off to another member just yesterday, I will be getting some more off Darren shortly but we have something else going on so it won't be until that is finished. Sorry Mate.

    EDIT: just tried to contact another member I sent a few too originally to see if he has a spare, but his phones not on at the moment, if he does I will give you his contact name.

    Hi,
    The egr was blocked at 147000 it now has 150000. It was done when he replaced the turbo at Townsville. He was coming back from the cape when his engine light came on so he got it diagnosed there as the turbo letting go. He couldn't get a compression test done, apparently no one in gympie has a long enough probe to do one. They were going to charge him$300-$400 to do so he decided against it. So now I'm not so sure as he has pulled the motor off his truck. Going by when I test drive,I did do a thorough check around the engine bay. Discussed what type of work and conditions the truck was exposed to. He was pretty happy with it. He was towing a 18ft caravan with a dingy on the roof. He's travelled around Australia with it. The only reason he's selling the motor is doing a v8 conversion as he will be pulling a much bigger caravan. He wants $5000 for it. Now that he wasn't able to do a compression test what would be a reasonable offer for it.

    When did the owner have the EGR blocked? If it was done pretty early, it will help the motor last longer. You should also see what boost the motor is running when it driving to see if it is boost spiking. Even with the EGR blocked, repeated high boost levels above 22 psi will cause the EGT in the cylinders to reach temps above the normal operation and material strength of the pistons.



    Nissan Specifications for ZD30 Compression cranking at 200rpm:

    Standard: 2,942 kPa, 29.42 bar, 30.0 kg/cm2, 427 psi
    Minimum: 2,452 kPa, 24.52 bar, 25.00 kg/cm2, 356 psi
    Differential limit between cylinders: 292 kPa, 2.94 bar, 3.0 kg/cm2, 43 psi



    Let me know how you go.



    Cheers,
    Niles

    Hi,


    Truck has been slow progress, but I will have an update over the easter break as I have the motor back now, ready to go back in.


    If I was buying a Patrol with a ZD30 or a ZD30 motor, this is what I would look for and do to know what condition the motor is in:


    1. First thing, get a compression and leakdown test. A good mechanic should be able to do both. The leakdown test is the most important one as it will give you results to see if you have cracked pistons or cracks in the head.
    2. Check the amount of crankcase fumes by removing the oil filler cap while its running. If its pretty smokey and you also encounter a fair bit of pressure (you can place the palm of you hand over the oil filler hole and see how much pressure is in the crankcase)


    If these come up good, then you might have a reasonable motor. The pistons in 03 models are the same as 2000. I think they changed them in the 2004 model ZD30's, but I'm not 100%.

    Mine was mostly just air into the coolant, which in turn pushed the coolant out of the radiator. My head gasket was cracked between the cyclinders, but not near oil lines. So the mechanic, strip the motor down. Remove intercooler, remove turbo, remove rocker cover, remove head. I dont even think we lost any oil, but you would need to clean yours. He sent the head off to ensure it was okay, and luckily it was. So then new head gaskets, and other gaskets and put everything back on. THere was a lot of parts sitting on the table when it was stripped.

    Yours sounds worse, hopefully it is only a head gasket. I went with this guy coz he was cheap, but he also was the only one that let me know what he needed to do and sounded like he knew what he was doing.

    Over 7,000kms on and no problems. RIng around, my guy was actually a wrecker, but they also did engine swaps and other stuff.

    Fingers crossed. Oh yeah mine has only done 148000kms. and is series 3.
