Remote Oil Filter Mount Hose Leak

[Skidave]

I know this topic came up before about the Excalibur 330 and maybe 343 remote oil filter hoses leaking. I noticed this last year and this year I monitored the issue. The leak looks like it occurs around the crimp connector on both the supply and return lines. In the photo, you can see where the oil has collected on the collars. I placed paper towels in various areas to see if the leak was happening around the crimp (hose side) or just on the top side where the metal pipes meet the hose collars. Looks like it is just the metal pipe side. In the summer, there was no leak at all throughout the season. It only occurs over a long lay-up or cold temps. I store my boat in my garage (2 car, normal size for new construction) and I monitored the temperature in the engine compartment this winter. Nothing below 40'F. The fact it does not leak when hot is a good thing.

I know crimp fittings from hoses to pipes can be a problem. I had one go bad on my wife's car on the AC low pressure side. It was an easy repair I did with a refrigeration guy at work...and he said crimped hoses tend to fail like that often.

If you're sure it is the crimp, than this won't help you, but there was a known issue where the paint used on the filter mount sometimes wasn't prevented from getting into the threads of the oil fittings, and this would cause leaks. Might be something to check. This can also show up at the filter seal, so if you get a leak there, check for paint on the lip and remove if necessary, being careful not to introduce scratches to the surface, which will also cause leaks.

Thanks Jeff. I looked at this in detail. I thought the oil might be leaking from the threaded fitting side on the filter mount and running down to the lip of the crimp. Not so.

Never had any issues with what you mentioned about the paint.

My hosed do the same thing. I tied a shop towel around the hoses. Doesn't leak enough to get the rag "oily", but will put a couple of drops in the bilge. Never really paid attention to when it was leaking, just noticed the oil sitting on the connectors and drops in the bilge.

Hey everyone
I have an 06 220 te and the remote oil line fittings are also leaking on the filter side. Can anyone tell me if both lines are the same?
