I've yet to find the innards of a 4C engine "dry" after a day of flying.

Yep...I always hose 'em down good with oil before the first break in run, and THOROUGHLY after a day of flying. Never had a problem.

For what it's worth, my newest OS .70's breather is located right next to the cam bearing. ALL the breather goo passes over the cam/bearings before it get's routed back to the intake for recirculation.

No castor? Shameful.
