I do hear it, but it sounds like an external rattle. ck to be sure your remote oil filter is tight, then all the other stuff that is bolted to the outside of the engine.

More obvious when I listen with stero headphones . You can definitely hear a pronounced rattle.Maybe because I don’t have a decent speaker available to me right now but on my cell phone I don’t really hear anything. You said you took a good look around, how about up front in thebelt tensioner area?
Does it still do it when you drop it into gear? If it sounds like a general central ticking it could be valves. Take the oil fill cap off and listen. Louder?
Were valves ever adjusted? How many hours on engines?
Don’t fear valve adjustment, piece of cake. You’ll get it sorted out. Good luck
How many hours did the major items have on them?... I know salt water will speed things up, was just curiousOk. I hope I am done. I bought the boat in late 2013. That's at the end if it's 13th season. I didn't know enough to know at the time, but just about all the bolt ons to the engines were at or near end of life. Since purchase I have:
Replaced seawater pumps
Pressure tested heat exchangers
Replaced aftercoolers
Replaced gear oil coolers
Rebuilt both turbos
Replaced wet exhaust mixers
Replaced all seawater hoses
Replaced all clamps
Replaced aft seawater pipes
Removed air grid heater circuitry
Removed fuel coolers
Replaced port alternator
Adjusted valve lash
Tuned props to 22.7 pitch
The boat had about 1050 hours on it when I bought it. It now has 1900 hours. It has been a southeast salt boat it's entire life.How many hours did the major items have on them?... I know salt water will speed things up, was just curious
Yeah, well it bothers me enough that I called a tech in for this one. One that knows my engines well. I’ll let you know what we learn on Friday.
Great news. I have worked on that sender. Easy to get to from above. I had no problem. Of course I don't have all the air heater crap in the way anymore. My bouncing gauge turned out to be a failed ring connector on the wire end at the sender. Not the sender itself.As it turns out, this was a total non-issue. The engine is running great. The rattling I heard was not the valves at all but a loose lower bolt on the oil filter bracket. It was intermittent and didn’t rattle all the time and sometimes disappeared with increased RPM. And it wasn’t so loose that you’d feel it if you touched the filter. But that’s what it was. I feel I could have found this, so I’m a little humbled by this. And annoyed – I think I would have found this in another month when I changed my oil! Oh well, I got to chat with the tech about my tachs (he verified they were spot on – which means I need a slight re-propping) and we discussed changing the oil pressure sender on the port engine (ugh) and winterization. But no problems with the valves or the innards of the engine. Whew!
And thanks for all the tips. I'm going to look back into the service records and see when the valves and tensioners were last worked on...

also, several of us have found that once the valves are adjusted the first time, they stay pretty stable from then on. If you find they have been done, you may be in good shape.
Sorry for the confusion. I am attempting to get the pictures to upload correctly.
Anyway, we painted the engines, rebuilt the turbos, replaced all hoses, powercoated the aftercoolers, elbows, and piping. Also replaced wire loom and zipties. Just generally freshened everything up.
I still have the Genset to do as well as paint the turbos with Ceremic high heat paint and replace the fuel coolers which I also had powercoated.
For reference I used Rust-Oleum Canvas White paint with some Majic hardener added. I handpainted everthing after wire brushing and treating with Ospho.
The engine room lights are Lumitec Ibiza and there is such thing as "wire loom tape" which is absolutely amazing and available on Amazon.
The after bilge under the Genset is painted with Interlux Bilge Kote Gray and I plan to expand this once I finish he other detail work back there.
If you see anything out of the ordinary feel free to let me know.
