Attempted to change my oil. Oil exchanger pump pulled the old oil out, but did not have enough suction to pull new oil out of 5 gallon container. Is there some kind of fix or just buy a new pump?

This is where I get my impellers for it. I always order 2 to make sure an extra is on hand. One year while draining the oils the impeller went bad after the first engine. I was stuck for a few days waiting on the new impeller. :)

How do you fill from a 5 gallon bucket?

I buy Rotella by the case (3x 1gal) from Costco when on sale. Clearly I have to buy quite a few cases but it's a lot easier for me to handle. I can easily pour into a funnel on the oil fill. Even a little bit of OCD is a pain in the ass.
 
OK guys. Thank you very much. On my Cat 3208s, the oil fill is only 4 inches or so below the cockpit deck. Makes it a little difficult, but that is what I will do. I will get the new impellers. Thanks again guys.
 
Buy an extra couple of gallons to sacrifice. After you have drained the old oil reverse the pump and add a gallon of new. Then remove that oil prior to the full fill. It does a decent job of cleaning the hoses and pump.

Sounds like a plan, now if i could just find some Rotella based on the current $25 bbl crude.
 
I find that on the 460 there's not much room to pour in the oil from above. I do the same as fr8dog and waste some oil to clean the lines, then pump from below.
 
Purchased a new iPad to go with the new Garmin 8612xsv which replaced the Raymarine E120. I found the placement of where the Raymarine E120 was less than ideal. Instead of spending big bucks for fiberglass redesign and rebuilding, I bought the iPad Pro and a Ram Suction mount and have mounted the iPad on the starboard side window next to the helm. I now have my chart plotter screen conveniently located and inside of my instrument scan. Yup, ya gotta love the technology.

I know some of you will want pictures and I will post them next time I get down to the boat, hopefully within the next couple of days.
 
My 20 year old 460DA has a Westerbeke generator with about 300 hours on it. It was working fine with no apparent problems when I purchased the bought last December. At the end of last month I decided to do a complete oil and filter change, fuel filter change, new zincs, etc. Everything on both engines and generator so I would have a base. Did oil analysis on both engines, generator, and transmissions which came back perfect. When the generator was completed, the mechanic and I started it up and the oil pressure pegged the needle at 100 PSI, well above norm. We ran it for a short while to see what would happen when the oil warmed up. No joy. He took apart the pressure relief valve and it was not stuck and appeared to be working. He put an inline pressure gauge in to make sure we didn't have a bad sending unit. The pressure there indicated 65 psi, still high but much better. Also started seeing some blue smoke coming from the exhaust which I never had before. I have been reading as much as I can and have seen that sometimes it is possible to get a faulty oil filter. We also put in 15w 40 synthetic blend oil. I have also read that in South Florida some people prefer to run straight 30w oil. I have asked my mechanic to drain the new 15w 40 oil change it out for 30w and to put on another new oil filter. After that, I don't know what to do next. Certainly a 300 hr engine should not need a major overhaul. Any input would be welcomed.

Lack of use has killed more generators than you can shake a stick at... 300 hours on 20 year old gennie is not much use... Sorry to hear about this and hopefully it will be not too painful.

My vote is the oil filter.
 
So just going off what you’ve described I would say this.

replace the gauge. The gauges are notoriously bad.
Replace the oil filter, it’s cheap enough who cares.
Oil wise use 15/40 it’s fine. If you want in Fl then go to 40w. 30 is thin at temp.
Adjust the valves, it’s easy as well


Report back with the results.

Yup, said the same to my mechanic. No real use over a 20 year period. Who knows what evil lurks.... I'm afraid to say this out loud but it may be a bad valve or even a ring. Putting fresh oil into in must have been a shock to its system. However, the oil analysis was good.
 
Westerbeke manuals are very specific on oil type and viscosity. They specify SAE 30, only..and an annual or 100 hour oil change interval, whichever comes first.

With 100psi oil pressure the blue smoke is likely coming from over oiling the engine and the excess oil flooding the valve seals on top of the cylinder head and running down into the combustion chamber where it is burned off.

What oil filter was used? Westerbeke filters, are expensive, but are very good and worth the added expense. Some aftermarket filters use a common cheap by pass valve and fail to release the excess pressure but send on to the engine's oil galleries, so I think you might be right on your diagnosis.

The little Westerbeke 8.0 diesel is nearly bullet proof so this is probably just going to be a speed bump on your way to establishing a base line on your boat's system's maintenance.
