Re: Can this be fixed
Not sure if it can be repaired given where it is and how far it has spread. I'm no expert though, it might pay to check with an engine rebuilder.

Re: re-commissioning my 4xv
That would explain it! Mine has a similar fault, but it has 5jj clocks so no relay. I should check the wiring.
