Brief Description:  Low quality components have to go

After not only dealing with a long run of blowby myself, but hearing more and more owners complain of it, I've wanted to see why the air oil separator that comes with the engine is just not doing its job. Knowing an upgrade is on the list, I went ahead and dedicated the UL Power separator to science. I chopped off the top of it using a band saw to see what complex design features awaited me only to find a complete JOKE of a separator. What a sad excuse for what UL calls an air oil separator. I will be writing up a blog specifically dedicated to this crap at my new UL power blogsite: www.myulpower.com. Which, on a side note has got a "lot" of attention and readers from Belgium. Hmmmm, wonder who that could be ;)
Basically, what we have here is a large round cylinder that supposedly swirls the oil around and lets it drain back into the engine while venting off the positive crankcase pressure to the atmosphere. However, without requiring the oil to work it's way past obsticles in order to leave the aircraft, it will simply get sucked right out the crancase tube. Lame design. Now, compare the UL separator to a high quality Dyno tested and designed unit from "www.AntiSplatAero.com" and see a world of difference. Like Kia vs Rolls Royce. No comparison. But, of course, let's let the desing speak for itself over the next several years of flying.
