Can anyone help me. The rocker shaft snapped on my 300 TDi Defender a couple of weeks ago. Replaced this along with the following items to cylinder 4. New tappets, pushrods, rockers, valves, springs, cotters, top retainers, tappet adjusters, injector, new head gasket, head bolts etc.
Was running ok but then today it started to judder and not run properly. I was about 8 miles from home so slowed down to 20-30 mph to get home. On the way it seemed to clear itself and I tentalively increased the speed to 50. Looked under the bonnet and everything looks ok. Had the rocker cover off tonight and it all looks good, everything in its place. Had the turbo inlet off and the turbo spins freely and no side play in the shaft. Started it up again and it seems ok, no strange noises. I don't want to take it out until I have checked a bit more.
The only other thing I have done is fill it with diesel and add some wynns injection system cleaner.
I was concerned about the cam belt but this was changed about 12000 miles ago.
Does anyone have any ideas what the problem might be?
Thanks in advance for your help.
