OIL GONE! ZIP! NADA!

Northchannel, yesterday I read a forum post about a Universal M25 diesel with the same problem as yours. His oil drain plug vibrated (further comment withheld) loose and fell out. You have the same threaded plug immediately behind the flywheel on the starter side of the engine.

Thanks. I'm sure I checked it but I will look at it again.

Marthur, NCYC. I was in Killarney before as well.

The mystery is FINALLY solved. The oil pan is cracked??! Ice?? I do know the boat flooded one winter according to the PO.

Are all the oil pans the same each year?

The lift

[northchannelsailor]

The current status. The mounts look sketchy. I will post pictures.

[northchannelsailor]

They look like rubber belting. Should I do something different? Any other advice for the pan swap?

[northchannelsailor]

Here is one of the two forward mounts. They have two shims as well. Don’t think it cuts the mustard so badly compressed.

Looks like a failed DIY attempt to make rubber mounts.

[northchannelsailor]

Or old school?

I hadn't seen any of this thread until now, but I give you an A+ for the courtesy of an update two years later! Thank you!

Yes. I sailed around two seasons without an engine before I got to the job. I had made time this spring but Covid caused our club to lock the gate.

I just got a replacement pan today. Waiting for my gasket order from MM.

It has occurred to me after looking at this kind of job, what likely was the cause of the cracked oil pan. I can imagine a pry bar being slipped under the engine in either the installation or in the shaft alignment. Looking closely at the pan I see a gouge where the crack is. FYI don’t pry your engine into place with metal bar!

Tomorrow is another day

Ready to go back into the engine bay. Fingers crossed. A few challenges like a broken stud and alignment of the gasket etc but I think it’s good to go!

[northchannelsailor]

Alignment purgatory. That was painful.
