Hi Jonathan,



Europa Aviation sell silicone hoses for oil and coolant and they are excellent quality. The oil return line is moulded to the correct shape for the return to the oil tank. In my opinion, for that hose it is certainly worth using silicone as it is directly above the exhaust system. Sheath it with Thermotec sleeving or similar anyway to help protect it. The biggest risk to silicone hoses is cutting them with incorrect hose clamps.

 Several years ago I bought a set of silicone hoses from someone in Sweden who created

 shaped coolant hoses for the Europa and also provided silicone hoses with

 protective lining for the oil system. He no longer makes or provides these

 items. Someone, but I can't remember who, stated that these hoses would last at

 least twice as long as the rubber types and I have no reason to doubt that.

 

 However my engine is currently off the aircraft, so a fellow pilot who has a minor

 share of the aircraft would like the oil hoses to be replaced by rubber originals,

 even though the silicone looks and feels supple, as good as new! I would

 prefer to continue with silicone, because the recommendation is to replace

 ALL rubber items every 5 years. The oil hoses are the difficult ones to access,

 particularly the return line from the crankcase. But I must also consider my

 friend's opinion.

 

 So two questions, pertaining only to the oil hoses. What's the problem with continuing

 to use lined silicone hoses for the oil? What specification do you recommend

 for the rubber oil hoses, which I hope to purchase from a local automotive

 parts supplier?

I tried silicone hoses water but found that i damaged the outer sheathing while wrestling them into place.  Probably my fault.     Reverted to the rotax spec.

As for changing rubber every 5 years i see it as an opportunity to have a really good look around in those inaccessible areas.

I used parker 836 pushlok for oil on buds recommendation and it has worked well.   I protect all hose with thermotec velcro sleeve.
