Oil cooler breaking
What would you do here? Check the pic. The banjo casing is cracking. Inside of it is a rubber hose. So far I’m getting a slow oil drip. Maybe a teaspoon a day or less depending on ride time.
My main worry is it will get worse or completely let go on a long ride or hot day. Due to the clearance issues I do see how I can run the lines differently and the more I mess with it I’m sure I’ll break what’s left. Ideas?? *Seller sold out, other sellers not responsive. The other end screws into the coolers filter so sourcing a identical new one doesn’t seem |

Thanks. I have plenty of length in the braided hose. Do you think I can get a male ended banjo fitted into it? Also not 100% sure where to source those banjo fittings.

Could it be repaired with JB Weld or some other product?

I might be able to. High temp gasket maker/RTV or maybe even solder it?

I, for sure, wouldn't run it until you get it fixed. I would finish removing the pipe where it's broken, tap the banjo fitting (where the pipe used to go) for a barb fitting (any hardware store has brass barb fittings that are male pipe thread on the other end) and put a short piece of hose in between.

Fortunately, the seal isn't compromised, though obviously stressed. As I said, no leak, no issue.

Something like this should get you out of trouble. Just need to find the correct banjo bolt diameter and pipe barb measurements.

It won't really be ridable until fixed. It could be capped off while waiting for the replacement line. M10-1.0 or M10-1.25 bolts ??

Two simple solutions come to my mind here. Take it off and reinstall the factory end plug. You DID keep that right? Lots of folks riding around happily with no coolers.
Second would be just to buy a whole new cooler kit. Rob the part you need or just upgrade it all. |

When that type of oil cooler leaks it can suck air and starve the engine of oil.

I agree with Gypsy. Put your stock cap/filter back on until you sort out the oil cooler. Then you can ride without concern of accident or failure caused by the leak.
It appears that the top hose was leveraged between the engine case and the lower hose/fitting. The way these bikes vibrate (at least mine) I wouldn't be comfortable having those hoses and fittings crammed tight together like that. The adapter needs rotated counterclockwise to create more space for the hoses and fittings.

Seems like the lines are in the perfect place. It almost looks like it was done to access the case bolt. The lower hose needs to be tilted down a touch and the upper one needs to be taken off and repaired, however you choose. They aren’t under any big pressure. My observation and this is what I’d do
