Had an oil line break off the oil cooler tube!!


Recommended Posts

We had surfed all day yesterday, and were heading back to the dock when I started losing oil pressure. Shut it down immediately and smelled oil. Popped the back hatch and there was oil everywhere. The rear most line on the oil cooler tube had broken off at the threads of the fitting!! 

Doesnt look like a huge deal to fix, cleaning up all the oil will be worse, but what a effed up thing to happen. Motor is an L96 with 260 hours. Anyone ever see this happen?

There should have been no reason to ever overtighten those fittings. They just have straight threads and O-rings to seal the fitting in the cooler so unless the o-ring is damaged they don't need to be very tight to prevent them from leaking. The oil lines are retained in the fittings with an internal snap ring. There is a special  tool that goes over the oil line and pushes into the fitting to release the oil line from the fitting.

Looks like some type of lateral stress caused it to break. Once back together I would make sure the cooler is not hanging by the lines or so forth

Oil cooler is secure with no movement.

This is what I think the problem is. While in there diagnosing and cleaning up oil, I figured I'd just go ahead and take it out. With less than a 1/4 turn on the next fitting, it broke off at the threads as well. At that point, I was pissed and stopped. 

Now, I just need to figure out where I want to take it for the warranty work to be done. That will depend on who can get it done the quickest. Closest dealer to me is 230 miles away!!

gonna see if I can get the threads out with an ez out.

 

Engine nut, can I order those 90 degree fittings and replace them on the hose, or will I  Need all new hoses?

Engine Nut said something about a special tool? Maybe pm him for more info before going the easyout route?

 You need a special tool to crimp the fittings into the lines. An ez out extractor will be the only way to get the broken threads out of the flange on the actual cooler.

Why does it look like there is a huge dent in it? If so I don't think I would reuse it

It's not, I thought that too when I first looked at it. The cooler is actually copper I believe, so it does have a small imprint in from the tab it was hose clamped to to secure it. It's mostly just paint flaking away that makes it look that way tho.

 

if I can't get the threads out with out damaging the flanges/bungs, I'll be ordering a new oil cooler tube anyway.

 

so want to take this to a dealer to fix under warranty, but it's such an easy fix, I really don't want to travel 3 1/2 hours one way to leave my boat for who knows how long?
