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 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.

Maaate!

Even Vans doesn't always get it right  (see recent advisory on nose wheel) any way you can "help" your engine/aircraft will make for a safer/longer service life.

The muffler/silencer is probably delivering nearly as much radiant heat, as the exhaust pipe/headers - anything close will be influenced/impacted.

Your "rubber" (vulnerable) oil hose (within orange fire sleeve) will be exposed to heat, that it doesn't have to endure. Your choice.

"...........fireproof flexible hose covering"

At best, fire resistant and limited heat insulation - if subjected to enough heat, will act like an oven, cooking whatever is within.
