yes 3 failure of the older 4.2’s sadly
1 x clutch collapse
1 x f1 pump failure
1 x pipe of doom split
the later I had and was willing to take all the scuttle and plenum off and replace but as the breakdown would only pickup and drop once, the chance of possible head gasket or other complication would have left the owner having to arrange and pay for his own repatriation it was risky and rightly declined.
It happens to us all at some point, myself a clutch collapse on my grey GS, they are all in hire cars now, smiling again and stripping somebody else’s tyres.
