After months of planning, weeks of accumulating pumps, valves, fittings, hoses, clamps, stainless steel tank, and days of installation the system is up and running. With 90 connections I had only two small leaks which were easy to fix.
The system basically allows me to pump old oil out of and new oil into the main engine, gen-set, the engine bypass filter, and the gen-set bypass filter individually. I installed a bypass filter on each engine and an oil level sight glass on the main.
I first intalled the sight glass oil pan connection and the GCF bypass filter reurn to the same tee welded to the oil plug but the pressure from the returning oil forced the sight glass level up. Fortunately the JD oil pan has two plugs so I rerouted the return line to another plug and now it works fine.

Randal,
Very nice, you have done a great job! Where does the spent oil go?

Again, great job!

The spent oil has been plumbed into the stern fuel tank. I can dilute it with diesel fuel in that tank, polish it and further dilute it by pumping portions into the salon tanks, polish it again and dilute it the third time by pumping it into the cruise tank. I know there are people who scoff at the idea of burning used oil in an engine but this engine is different, it's mine.
If the used oil has enough contaminants in it to hurt the engine above the pistons there are problems below the pistons, besides, look at the times I dilute and filter it.

Randal,

You have really done a great job! I firmly believe that the easier it is to do a certain job, the more likely it is that it will be done!

Again, outstanding!

Hi

I am impressed by your installation . I was wondering if Sea Horse Marine will offer , this type of options or if they have it now

Thank you for information

If anyone is thinking of adding an oil change system I would recommend the use of 3/8" fuel hose running to and from the pump manifold. I used 1/4" and it takes two hours to pump the oil in and out of the main engine crankcase. I did use 3/8" valves so I may go to the trouble of changing it........someday.
