Hard to see much

[jim wick]

Photos are tough. It’s on the outboard side. Behind the aftercooler. Behind some wiring. Against the hull. With a mirror I can see it on a couple of the aft pan gasket bolts but it comes from just above the pan. Then it makes its way Aft over to the (Bell housing?) and then down.

I keep a cookie pan under it. I’m guessing one ounce oil every two hours of run time. Thanks rob.

Im 99 percent sure I got it. Wiring is a fickle bitch. bitch. I ran a new ground from the panel to the gauges. I hope that’s kosher. I guess the 30 foot run back to the engine through the harness was not doing it for me. No more low oil alarms. Volt meter reads 13.5 now instead of 11.5. Thanks everyone!

I installed good quality mechanical gauges after the cheap ones took a shit. 700 rpm the mechanicals say 25-30. Pilot house and fly both read 5.

I took a new gauge and hooked it to the VDO “D” sender and the battery right next to the sender. All new wire/crimps/gauge/sender. Reads 5.

Granted it’s a single gauge on a “D” sender. 5 was not what I was expecting.

Two of my 4 boards I got from you. I believe you changed the alarm so there was not so many false alarms.

corey, in another thread concerning low oil pressure you said…..

“You can place a 10-15 ohm resistor in-line on one of the sending unit wires to bump up the PSI value… the problem is that the Cummins spec is down to 5-6 PSI at idle but the alarm indicates at 8-10 PSI… hmmmm Who thought of that one?????”

Is this an option if it is my long wire run? 10-15 ohm? how many watt resister?

[jim wick]

clark, thanks. I will do it! Definitely a smart try before I buy and install another harness. thanks buddy

Corey, thanks as usual. I will take a better look/clean at the terminals and also take a picture. I did not notice any corrosion and since the problem is both sides and since this seems to have been a problem since new I did not give corrosion much of a thought. I do want to do a quick short run check just to narrow it down. Happy holidays

So after all the dust settled, the company did more than they had to, I’m good. They sent me a new pump. I was way out of warranty but they did more than they had to. They all but admitted fault, we all make mistakes. I still have the labor $ but it could have been worse.

It was rebuilt just before I bought it so I’m guessing they went cheap. After tear down we found that they used red RTV between the engine block and the gear case. I think a gasket is recommended. Anyway, they filled the oil passage to the fuel injector pump with RTV. 100 percent restricted oil flow to pump. Bosch gets credit for making it strong enough to run 500 plus hours with zero oil lubrication. I’m out of warranty and even if it was still under warranty I would have to remove it from the boat and ship it to Florida for their inspection. I’m guessing I’m out of luck. Looks like a $3000 pump repair and about the same in the labor. Be aware if cheap rebuilders.
