John,
Thanks for clearifying that for me. I will check the injector pump rather than the transfer pump.
No the engine is not apart nor is the injector pump as it is running quite good right now. But I heard that the head gasket is the main weakness in this mdl. So I am looking for these things for future use. I understand that the engine is a Fiat 615. I do not have the dimensions. Is it the length and width of the head at the gasket that you are looking for? Do you know if a head gasket can be fabricated and if so what kind of material would I use?
I think what happens is that the head bolts get wet and eventually rust through allowing the head gasket to begin leaking. So I am thinking about replacing the head bolts 1 by 1 with a grade 8 stainless steel if I can find them.
