If its what Im thinking, it should have a yellow cap and is the normal oil filler. its in front of the injector pump but has nothing to do with it.

That engine uses API grade CD ( which has been replaced by CF) and takes about 5 litres to fill full. ( doesn't need to be filled full),

heres a link to the owners manual http://www.yanmarmarine.com/theme/ya...Manual-ENG.pdf

Well this thread is several years old maybe I should start another but I'll give it a try. I'm trying to find the part number for a yanmar 4JH3E the part that's on the AFT end of the heat exchanger where the hose for the mixing elbow is connected. thanks in advance. And I clicked on the link for the manual but I can't download it, I'm trying to do with a smartphone maybe that's the problem.

The first link is only giving me the first 2 pages of the manual. The 2nd link and the link in the message before from goboatingnow are OK for me. Good luck.

Thanks for getting back to me. none of the links work for me but I think it might be because I'm using a smartphone. but I ended up calling marinedieselparts.com. Very good experience from a guy named Jim. he gave me the part number,price, and nearest dealer he even gave me their phone number, because MD could not ship it to me because of Yanmar policy to protect local dealers. By the way the price was $176. I think I'm going to have it welded.
