Default Oli Cooler line leak.

Original owner 2000 FLHTCUI. 43kMiles. At 40k we did the cam chest upgrade. Hydraulic, oil pump, cam.
In 23 years this bike has leaked zero times. On a 500 mile trip this past weekend it started.
From a weep/seep, to a leak of a teaspoon every running hour or so.
It is coming from where the Oli Cooler line exits the motor crankcase.
What is the best way to snug that fitting/ fix the leak?
Can you put a goop or tape that will seal that fitting, or just tighten and move the hose to the inside of the other?
Thanks.

If you look on parts diagram, I think there is an oring behind there.

Are we sure its not just the hose leaking ...try that first ..cut a little off and reclamp...
clean area and test ride to see if still leaking ...
if so ...pull fitting , add your favorite pipe dope/tape ...and retest !!
good luck ..!!!

Just shut up.

Obviously you didn’t look. So don’t say ‘if you look’ as you didn’t.

It’s a brass fitting.

If there’s an o-ring, it would be on the outside.

You have no mechanical idea or aptitude.

Straight up stupid.

You ever take a harley engine apart? Last year when I had my bottom end apart, I believe there was oring behind the stock fittings. As I said, look at a parts diagram. Maybe I am wrong, which is why I said took at a parts diagram. I was also thinking the other side. Which is why I said check the parts diagram. I was thinking oil filter adapter not line.

You ever pull a crank other than your own?


For fuc sake all I said was check the parts diagram to see if orings. I remember a number of orings in the bottom end.

The angled fitting moves with your fingers, we checked it hot and the drip really appears to be coming from where the fitting meets the crankcase..
Grateful for your replies.

If the hoses are 23 years old, I'd replace them. I'd use Locktite 567 or permatex high temp thread sealant to seal the threads.

Nice try at a comeback, now go wipe your chin.

Brass fittings don’t incorporate o-rings on the bottom. No parts diagram needed.

If you’re going to try and keep talking, know what it is. As evidenced repeatedly you talk but have no idea. No bike. Nothing but incomprehensible nonsense about subjects you will never understand.

So yeah, I say again. Shut up. Por favor!

It upset you that I said check parts diagram? When he said oil cooler I was thinking oil filter base which does have o rings.

These look to be the lines that normally would go between engine and pan, if I am looking at it right.

Just throwing it out. I am the type that likes to check the manual.

You didn't answer, you ever tear apart a Harley engine?
