The damage to the head and block was so bad that I decided to go with the dealer fitted replacement/recon long engine from LR. No assistance from LR Australia because we're out of warranty, and no gesture of goodwill.
The route cause diagnosis was valve spring failure, it's snapped through the middle, I suspect a material defect but need to get it on a microscope to see if there are signs of inclusions or surface defects.
It was on the ramps last week, 99% complete, but they discovered that when the RAC stripped it down the rived out one of the hoses and snapped it! so far I've been extremely unimpressed by the RAC; some things are best left to the stealers.
We're just waiting for the hose from the UK; I was hoping to have the disco back this week, if only to give back the very kindly supplied Ssangyong Kyron; OMG what a car; the wipers fell off after 2 days and the water trap warning light blinks more often than the indicators!
