Hi just wanted to put out there that 4WD action had a really interesting article on caring or protecting your diesel engines, mainly directed at the 3L's. They discussed how over throttling can cause over heating in your exhaust and turbo without getting you anywhere quick. They suggested getting an EGT and boost gauge to monitor what's happening inside to help notice temp spikes sooner and more efficiently then just using your normal temp gauge which in a lot of cases can be a bit late once the temp has started to climb, especially in the 2.8L and the 3L which are vulnerable to temp spikes. I have a 2.8L so it really appealed to me as I am in the process of rebuilding the engine as the head cracked, so I decided to replace all internal parts (pistons,rings,bearings,etc) and do the job properly. Obviously they went into lot more detail and and had a few other segestions on how to protect your engines but the EGT and boost gauges were their top two suggestions.
