Onan MDKAW oil pan leak

[Mark Adams]

Greetings… new guy here. Looks to be a great resource. My situation is that I have an assumed oil pan failure on my Onan MDKAW mounted in a Nordic Tug 42. Summarizing…

• The boat sprouted an oil leak when it went on the hard a couple of years ago. This ~7 mo after going on the hard. 
• I mixed a quart of oil with some tracer UV dye and put it in thru the dipstick hole. Multiple days latency before a significant leak broke out, which took several days to empty that quart. 
• The oil level afterwards is below the dipstick. A welding rod shows <0.25″ in the pan. 
• I am assuming this is a pan failure. 
• I cannot see the exit point anywhere around the engine and partly due to the design of the generator and partly due to being ancient and used up, I cannot see between the generator and the pan. 

Some questions please..

• How big a pita is it to pull/swap or repair the pan in the engine room? 
• Is there any known reliable repair procedure to the pan? I’m a fairly good machinist… weak welder but know many good ones.
• Are pans available? I can’t find one. 
• Is there a resource where you can cross-reference the kubota engine and buy a pan from them?

Thanks in advance for any ideas or suggestions. 

M-A

My personal experience it that ONAN support is not good in S. Calif. I know I cannot do much with them.

Wish I had had a better answer.
