I had some seals replaced in it 4 years ago, but not the major overhaul which costs the big $ though. Surely I couldnt be lucky enough that its the same seals that have gone again. I guess I'll find out soon enough. At least last time it would start, even with diesel leaking everywhere, this time no start.. I understand that diesel pumps need to be timed or some such thing, which isnt something I could do. So its going to need towing to a mechanic. I was told the seals go more often in Australian diesels because of the crap quality of the fuel we get. Thanks croco, I will look at replacing the plugs too. 400k is a good run, I imagine it will keep going for a lot longer after the pumps fixed.
