Now that you have made the right decision to bring the patient into your warm winter operating room, it would be a good idea to write down some base line information. I'll try to list a few as they come into view. Oil pressure throughout your operating range, ditto engine temperatures, voltage at various locations, amperage, fuel consumption rate, exhaust back pressure. Take detailed pictures especially where leaks old and new might be present. This is a good time to invest in digital gauges. I might get thrown out of the barracks for saying this but don't be in a hurry to spend money on electronic ignition unless cost is no object. Because of your valve issues I suggest a scrutinizing of both valves and guides with a view to replacement where tolerances dictate. BTW, "diesel upgrade" is an expensive side stepping of the issue. All the best, Hanley
