Wouldn't have anything to do with the recent replacement of the timing belt, would it.Quote:

The problem was that they had taken the drive pulley off the end of the camshaft to replace the timing belt (buggered if I know why - I have done the job a number of times since and there is no need to touch this pulley at all) and had not re-fitted it correctly. As I was overtaking the truck, the drive pulley moved on the end of the cam and sheared the locating pin, allowing it to spin freely (the retaining bolt had not been properly tightened and loc-tite used). This resulted in a number of the valves doing a tap dance on top of the pistons.
I was very lucky in that no pistons were damaged, and I managed to source another complete head which I fitted myself. That engine went on to eventually clock over a million km.
