What a weekend took the head off as looked like one of the valves was sticking. Once off 6 of the push rods were bent but the valves seemed OK. I replaced all valves and push rods anyway. When tensioning the new timing belt the injector pump started leaking diesel through the shaft to the timing pully, took pump off and got a diesel engineer to check it they fitted a new seal and said the old one had gone hard with age -maybe that was why the belt snapped if it was getting diesel leaking on it. Got it all back on and set the timing then turned engine by hand to start valve clearances and valve was hitting piston aarhh. After checking everything again I had misread the manual and lined up the woodruf key on the crankshaft (as 300tdi) with the arrow instead of the dot on the gear. No damage though so re set the timing again and put all back together then set the tappets. All turned over fine.
Then got all fuel system / cooling etc back on and was filling with coolant and it started just leaking water from the head at approx No 3 piston on the exhaust side. Took head back off to find that I had put the gasket on upside down I think ???? the Landrover manual states the word DIESEL on the gasket should face up which I did, but when doing this the gasket is then the opposite way up from the old one I removed. Can anyone explain what way up the gasket should go? I have some photos to try and show more clearly but cannot figure out how to show them here.
