Where to route oil hoses

My oil lines go over the muffler as do most all of the nearly 800 RV-12 sold. I just finished the 5 year rubber replacement and routing went well.

Nice looking! My radiator is up high (Remos), so I gotta go over the top. But, I’d guess that muffler is hotter than my crankcase, so maybe I don’t have to be so concerned with heat. 

Hi Wallace,

How/where is your Oil Cooler secured?

Why does the Cooler to Oil Pump line not go direct/shortest rout?

If it were my aircraft, I would be having some form of additional heat protection (shielding/wrap), for the oil lines, just where they are closest to the muffler/silencer.

Hi Robert,

The oil in the line is not so much cooler than the crankcase, so the orange fire sleeve is probably sufficient insulation.

I would be more concerned with the potential for the hot oil line to add unnecessary heat to your ignition modules & fuel lines

Hi Sean, my oil cooler attaches to the bottom cowl. In my picture above it was just hanging loose, until I re-install the cowling. All my lines are all protected by fireproof flexible hose covering. Van's has nearly 800 of these RV-12's this way and the oil lines are working good.
