Hi Chazalby,
You can see it on the bottom left picture. It goes into a plastic elbow on the intake tube that feeds the Provent catchcan. It should work if you connect it anywhere between the MAF and...

If wire 22 goes to the converter locking solenoid on a GQ, then cutting it will prevent the converter from locking. You need to put power onto the solenoid to lock it.
If you have cut the wire, try...

There is a temperature switch inside the transmission which the TCU uses to help control it. Generally the transmission will not go into 4th or O/D until it's up to temp. Lockup should occur after...

Sorry, I can't help you with the manual - I haven't downloaded them.
It's always easier to pull the engine out to do a rebuild, but if you're just going to replace the pistons, it may be easier to...

Magician, yes there are three bolts at the rear of the sump that need to be accessed from in the back, so yes unfortunately the transmission and bell housing need to be removed or at least moved back...

The when is now! The old track to Mt Caernarvon is now open again with a new section to complete a loop solely on the Bunkers Conservation Reserve. At this stage it's only open on long weekends and...

I'm still very happy with them. I've now done about 60K on 6 of them and the worst one is down to about 7mm of tread. They are getting slightly noisier, but that's to be expected. So far no...

Sorry guy’s, I missed this thread. I took the site down for a few weeks over Feb due to someone hacking my passwords and uploading viral content. All fixed now and the site is back up.
Cheers,

Yes true, the Navara’s do have similar problems, but not to the same degree…..

The Navara turbo uses a waste gate and doesn’t have a MAF, which I suspect has more to do with their improved...

Hi E.T.

I definitely don’t baby the ZD30. I like to get it up on boost ASAP and keep it in the zone (so to speak) which is normally between 10 and 12psi in my case, unless I get off the throttle....

Evil Twin, very well explained!

Just if I may add - people often ask why we would want to slow down the spool rate. There are several good reasons. The factory spool rate is quite fast and VNT’s...

The simple answer is that while all modern diesels do operate with some level EGR, the ZD30 uses very high levels. Peugot do have their problems also as do many other manufacturers, but the Nissan...

Turn the screw clockwise to reduce boost and spoolup. This makes the actuator arm stop before it reaches full travel and reduces the amount of opening the turbos variable vanes can achieve.

Tony,

There’s been a lot of talk recently about inlet system cleaning and what to use or how to go about it. I have removed my throttle body and washed it in petrol, which did a good job of...

The Dawes and Needle valves are two separate items and one shouldn’t affect the other. The Dawes will limit maximum boost and the Needle valve will control the spool rate or how quickly the boost...

The Dawes needs to be adjusted so that it will allow the boost to hold at 15psi. This is usually a safe limit below 3000rpm because if you go above that for more than a few seconds, it'll most likely...

mudski,

Those figures that I quoted are generally conservative safe levels for setting up. You can go a bit higher if you like, but then you may have limp mode issues and need to go back a bit.
...

Lucas, yes there's a good chance that it may be an earthing issue. I can't remember if the Jatco box engages 4th gear through the temp switch or not, but some 4 speed transmissions do and in that...

Thanks teno45, just beat me to it……….

Lucas,
You’re problem may just be a bad electrical connection at one of the plugs to the transmission or TCU. Even a damaged wire that open circuits with...

Thanks mate, just being modest.
I've also come across a few that don't recomend them because they're not familiar with the Dawes valve. Initially we were looking at fitting a convenional wastgate...

Hi Rusty,
It sounds like you hit a similar wall as I did when searching for the Wynns EGR3. I don’t understand why it’s sold in the eastern states and not here in Adelaide by REPCO. If you know...

Ben81C,

It sounds like none of your mechanic mates or diesel specialist are familiar with the VNT controlled turbochargers used in almost all late model diesel cars. Variable nozzle turbochargers...

I misunderstood teno45’s question. The answer is that it can’t lock, so nothing happens unless you have your foot on the switch as you take it out of Park. Then it will stall the car.

Excellent write up ripper! And a job very well done. Shame about the TCU, but like most of us that have the system fitted, you'll always control it manually from now on.

I also got sick of the...

Any non LSD oil should be suitable in the 70-90 weight range. I'd also use some anti-friction additive like AW10 etc.
