Oil filler on Universal Diesel? (5424)

[MarkSF]

It might seem ridiculous, but where is the oil filler cap?

I checked the manuals and although you and I might think a diagram of the engine, showing it, would be a good idea, Medalist obviously didn't think so.

Assuming your 5424 is similar to the 5411 on my previous boat, right on top of the valve cover.

It's right on the top, as JimsCAL stated, and it's almost camoflauged, but it's there. It's a "thumb turn" cap, if that helps.
