re-chrome valve covers

I see that you also have, as Beau mentioned, the air intakes blowing right towards the outboard valve covers.
Maybe that has something to see with their (relatively) early corrosion.
Though I must say that the manifold, turbo, aftercooler and all the rest of the engine looks immaculate - I wish mine were as clean as yours!
Or did you possibly respray them, on top of the valve covers?

Thanks for your kind offer.
Yes, I have MANs as per my previous pic, and all the valve covers, outboard ones included, look still far from needing a repaint, in spite of the fact that they are older than yours (2003, with 1500+ hours).
But never say never! It certainly doesn't hurt to include any suggestions you can send me in my MAN folder, for future reference.
You can reach me via email using my username plus "@yahoo.com" as address.
Thanks in advance!

They are not moved also in my boat, and the same MAN dealer who used to support the builder on new installations told me that he always advises against remote oil filters installations.
According to him, even if it's a MAN approved alternative, it makes oil circulation upon startup a little bit longer.
But In practice, I think that's splitting hairs a bit, and to be honest I would have liked the convenience of having the filters inboard on both sides!

I was about to mention that. Even Slerays had the filters remotely mounted to the inside.
There may be a ready to bolt on kit available for you.

As much as I like a nice looking and clean ER, I can help wondering why would anyone want chrome accents down there.

the C32s on the boat i run had the chrome upgrade... chrome cam covers, chrome pipe to the aftercoolers (that went when the aftercoolers were upgraded...) and... clip on chrome Secondaries and Oil filter covers!! I mean why would anyone want to hide their filters !!! Don’t you want to spot a leak?

just like Lazzara installed powder coated solid doors in front of the chiller rack and the watermaker/fresh water pump rack. One of the first thing I did is pull that crap off. When I walk in the ER I want to see equipment... when running I want to be able to move the camera and see stuff, even zoom in the WM gauges or the chiller control panel.

machinery needs to be clean but functional

Awww, come on guys. A "little Chrome" never hurts! I was responsible for this house of mirrors as the build engineer. 2nd engineers job was to walk around the engine room with a roll of paper towels and Windex...

Different on a classic car... you go to a show you open the hood... on a boat nobody but the crew and mechanic see the ER.

Then they (crew and mechanics) curse the guy that spec'd all the mirrors and chrome...
Luv Ya Captholli but that was a curse on the crews forever.
Paint rules.

Unfortunately this Christensen was one hull behind the "King of engine room mirror stainless" John Staluppi's Casino Royale and once the owner of Odessa peered into his house of E.R. mirrors the die was cast for hull 34. Couldn't say no to the man paying the bills and convince him that a little stainless goes a long way with copious amounts of Snow White Awl-grip. Tried to talk him out of 50 % of it but failed. Odessa is ten yrs old now and a charter horse but the engine room still looks decent.

Then all is good.
You do have to find the rite crew (pay) to keep that mirror grade up.
