On that subject, to those running any kind of 5th bearing, is there any reason not to run an aluminum line from the bearing to the oil port? I know most "aircraft" engines with prop governors run stainless lines. A 3/8" aluminum line has a rated burst pressure of 300 psi or so (and that's with a 2x factor of safety.) The line on the 'vair is attached to the engine on both ends, and adel clamped at various locations along the length, so I can't imagine vibration/fatigue being an issue....
I'm thinking it's probably a good idea to run stainless, but just wanted to see what those with experience have done. Thoughts? Matt -----Original Message----- Hi Dan, The only thing I would suggest is putting stainless steel fittings in the 5th bearing if it is not and in the oil filter adapter that the 5th bearing oil line is attached to. It may not be as critical on the Corvair engine as compared to a Lycoming.
