Although this is on my Bucker, I wanted to post this here as it may be relevant to RV's, or any other aircraft.
A progressive oil leak developed from one hose feeding the Oil Cooler. I could not really tell if that is where the leak was coming from but I decided to build another hose and elliminate that as a possibility. I have always built my own hoses, Aeroquip brand or style. I did not build the hoses on my Bucker however.
Upon inspection of the hose, the Aeroquip fitting (not Aeroquip) looked odd from two stand points. The flare was larger than the Aeroquip and inside of the fitting smaller diameter. The really odd thing is the color of the fitting. Instead of the anodized shiny dark blue color, this fitting had a more matted robins egg color, or lighter blue. I did not notice this odd coloring as the fire sleeve and RTV covered much of it.
I could not tell if the flare angle was correct or not, but I changed out the 90deg. elbow into the cooler and discarded it and put a new fitting in along with the new hose.
Oil leak is now fixed.
I have not torn the hose or fitting apart yet to see if I can find any possible failure point but it appears normal from the outside.
Any thoughts?
