All,
Greatly appreciate all the input. Will start with the oil feed line. As I recall, the one on my engine may have been replaced once before, as there is a brass fitting at the back of the head. Will check out this weekend.
When I purchased the motor I had everything outside, clutch, pressure plate, head gasket, throw out bearing, fuel pump, valve cover gasket and all radiator hoses replaced. When the valves were adjusted the mechanic told me the inside of the engine was very clean and it did not appear anything else needed replaced. He confirmed the engine appeared to only have 5,200 miles on it. Could not perform the service myself, due to disabilities. I'm hoping this will be something I can do myself.
Will keep you all posted. Thank you all again.
Thank you, Howard
