Well the next stop for my Patrol is unfortunately likely to be off a cliff top as it's doing my head in and costing waaay to much to be justified now.
I've done NADS, all new hoses, new radiator, new thermostat, injectors, coolant flush, replaced MAF and it's still playing games with me. It's cost me well over $5000 so far and coolant is still disappearing at an unexplainable rate. There is definitely no external links and there is no steam out the exhaust, no milkyness anywhere in the oil or coolant, so where to now? And my cruise control has stopped working. It's looking like it maybe a cracked head and if that's the case then goodbye Pat unfortunately.
Yesterday it went to a new level when she went Engine warning light on, then wouldn't go anywhere in 1st (even after switching it on and off and making sure the coolant levels were as they should be) It's now at my mechanic again (I feel like I only get to borrow it on the weekends now) and I've just about hit my limits $$ wise. It's a damn shame really as I thoroughly enjoy my Patrol when she's running well, it's just now getting to hard to justify the expense of owning it.
The latest code is for the TPS so that will be fixed, but the big problem (and it has been being worked on for a long time now to fix) is where is all the bloody coolant going? There is now no evidence there is an internal OR external leak so what's going on? It may be a case of patch it and trade it!
Mind you, if I get rid of this I'll be buying another Patrol as I think they're awesome rigs- just not a ZD30 that's for sure as this one has put me off this engine for life!!!
Damn shame.

A few things i'd be checking
1. Have you done a pressure test on the coolant system? Is it holding pressure?
2. Is your engine oil milky or thinned out / discoloured (other than sooty black colour)?
3. Is there any sign in the engine bay of a leak (radiator cap / expansion bottle / cracked hoses )
4. Is your passenger floor wet? A sign that the heater core is holed, the coolant will drain down into the passenger foot well.
I would also check your malfunction codes as several codes can lead to bigger problems, but it may be a simple solution??????
