Crikey, you work fast Paul ! I'm still in the pre-contemplation stage... Investigation and cleaning of the head reveals it to be crack free and I couldn't find any warping with the straight edge method. One of the advantages of an alloy head though is it will recover from slight warping if I missed any. The head is now back on the car I did find possible gas marks between number 3 and the water jacket on the head surface so I suspect that was my leak. She would be running again today but I the manifold gasket disintergrated and I don't have a new one here. It may find its way back on with a broken one later though so I can test that the engine still works. As to working fast I have to mechanics is my day job, im self employed,and this car is my work transport so I can't afford it to be off the road. Besides I need it to go on land rover weekend event next weekend  |

Yep got a mate that's sold me the part so she'll be back up and running this afternoon. It certainly went with a good bang I suspect this was the cause of the 3 cyl moment and mad valve clearance opening of last week first time ive had a look since towing the tractor back. At least its an easy bit to change.

I must admit that I showed that photo to Martin and he was really surprised as he'd never seen one break its rocker shaft before. He says it's much more common that a pushrod would get bent. Just unlucky I think. Glad you got it sorted out.

Just unlucky I think. Glad you got it sorted out. The rocker shaft is held down by 3 studs and 2 bolts. The rear most stud worked its way loose so the rocker shaft wasn't effectively clamped down so the shaft was free to move slightly, lots of reciprical movement from push rod and valve spring caused it fatigue and fail. |

You want to check back through its history and see who last worked on the head, then give them a serious talking to!
