Yes he did lubricate it , general health is good , running perfect, oil lights goes off but we are thinking of seeing if we can get a aftermarket gauge ? The core came from UK turbos, pipes are clear , hence why we are totally stumped!
As my o/H has a disco 1 300tdi, we had a turbo go a few months ago , everything was ok till 2 weeks ago when the next one went , purchased a new core and again ran brill no problems , till yesterday morning, when coming around a roundabout, big cloud of smoke !! Another turbo gone!!! Now we know they must be something wrong , but not sure what , he checked the oil and level didn't seem up ?
