Boingers may be too optimistic a term for these engines. In my experience they should be called exploders, or at least immolators.

I always was thinking there was a disadvanatage to the boxer engines. Now I see the light. I just like that there is no grativational push or pull on those engines. That's the only plus that I see out of them.



Thanks. And I agree, they should be called rod throwers, demolishers, but not boingers.

 

The problem isn't that they are boxer or 180 degree engines, the problem is that they are air cooled, and because of this the oil really takes a beating, since liquids make a more efficient and consistent conductor of heat than air.



In addition, the aircooled design dictates an external method of oil routing, there being no real place to put oil galleries given the separate crankcase and cylinders and heads. This almost guarantees oil leakage.



When you factor in the historically crappy German rubber that is used in the hoses, you have almost guaranteed yourself trouble. Thus, the engine fires, or at a minimum, spreading vast quantities of oil on the track. External oil lines are works of the devil and should be avoided whenever possible.

 

thats why you use 3000 psi braided hydraulic hoses for 100 psi oil lines!



lol

 

also, most of us dont drive our cars daily. So we change the oil more often on a mile basis, but the time is usually aroudn the same...if you catch waht im saying.
