Rotec R2800 oil drain problem.

[paulc]

I've got a Rotec R2800 radial on a Kitfox IV with an oil leak problem. When my engine is sitting, it drains a considerable amount of oil out of the exhaust stacks and intake drains.

That's not an oil leak problem, that's simply your engine being a radial

Hey Paul,
I recently removed my engine from the fuselage for fabric and paint....I'm getting there little by little.

Is it possible after shutdown to clock the engine so the open exhaust valve is the #1 cylinder? Would that prevent oil from leaking out the exhaust pipes?

Regards, Don

Don thats going to be pretty hard to do seeing as the prop is not directly connected to the crank, its a geared engine. It really matters not what valves if any are open on shut down as I catch the oil from both the intake and exhausts. This is the only place a radial will bleed oil. The electric scavenge pump (i dont have) reduces the amount of oil trapped in the engine after shut down and thus the amount of oil dribble.
Embrace the oil! Like hand propping, before the smokey start up, its all part of the radial deal and Rotec give give this feature as standard at no extra charge!

Paul, Regarding the "oil embracing" aspect of flying a radial.....sometimes my Lycoming starts with a "chug, chug, chug" with the extra smoke.
It is cool
