OK, due to low oil pressure i dropped the pan on the Z134 engine. Engine runs great, spark plug reads are good, does not smoke, no knocks, and all indications are its a good mid life engine except for low oil pressure. When engine starts, oil pressure gauge barely lifts off, does not quite get out of red, and increasing rpm has virtually no effect. Second oil gauge I have tried. I have pulled the spring and parts from relief valve, the piston seems free but will not easily come out with spring. Spring lenght and spec is ok.
So, its spring and taxes are due and I have no time so I need to do what I can and get it back together until next winter.
Do the oil pumps themselves wear out on these? The rod end play seems good, although I might be detecting a bit of up and down movement.
My first thought is to replace oil pump, and/or the rod bearings, and put it back together and see-your thoughts are appreciated.
