That's a good idea, Ferdman. I have a new coil coming and I will be buying new spark plugs and a fuel filter (cheap insurance)today. I'm sure you are right about the oil by-passing, the car is long overdue to have the valve stem oil seals replaced. I'm off the next couple of days. I will let you know what happens.
Thanks,
Colin.
