Hi there I have a problem with oil pressure on my 1972 4900 Indy. The oil pressure has always been low, but I guess the flow is OK. That seems to be normal, according to the threads in here. But now the oil lamp is sometimes blinking. I hope it is not the oil pump. Is there any special known problems with that? I have the manual, but I believe it is very difficult to see how the oil pump is working. Is it correct, that it is driven direct from the crank inside the engine? First I want to change filters and oil an extra time, I guess that is the first thing to do. What make and type of oil filter are You using? What oil type? Amount incl filter? Any other suggestions, that I could try? Thank You guys, in advance.
