When I restored my 240 about 10 years ago I took the precaution of having hsrdened valve seats fitted. Now the cars has only done a few thousand miles since. In the past couple of weeks it develpoed a tapping noise in number 5 cylinder. Yesterday it turned into a loud knock and went off a cylinder. I took the head off last night. The exhaust valve seat has dropped out and the valve is jammed and looks bent. There are contact marks on the piston but jts looks ok.
Do you thjnk I should have any come back with the company that did the valves given the low miles even though it was 10 years ago?
