Re: Walter - any theories on Oil Seps.

JK:

I have them on my Twin Beech and they make a lot of difference in the amount of oil which is blown out of the breather.  These are lose engines.  They work.  Are they worth it on a 470, 520 or 550 or any of the lycomings??  I don't know as I think that's a function of how healthy the engine is and how anal you are about oil on the belly!  <g>  Are they necessary?  Not on a healthy engine.

In a healthy engine, they are a nice way to keep the belly a lot cleaner.  They tend to cover up high crank case pressure from bad rings in an unhealthy engine.

Do they work as advertised?  In my expereince, yes.  Are they worth it?   It depends!

How's that for a non-commital answer? <g>

Re: Walter - any theories on Oil Seps.

in an in depth test done buy aviation consumer on air oil separator they work as advertised most of time but not on some installations .
mostly they dont recommend them for plane not flying very regularly are a source of condensation so internal rust .
i instaled intead on my skylane an stc muffler made by acorn welding in winnipeg that is over 3 inches longer and it does the job of keeping the belly clean

Walter, Good answer..  What would happen, on a "conventional" vented engine, if the vent fumes were induced into the lower part of the exiting exhaust system??  Wouldn't that burn up the fumes and thus, eliminate the oily belly??  It is done on the T-63 turbine engine installed on the Bell 206.

Keeping the belly clean with a longer muffler helps keep the exhaust stains off.  The oil comes out of the breather and has nothing to do with the length of the exhaust stack.  If you are getting oil coming out of the exhaust, something really, really bad is going on.

Yes, if the oil return is vented into the exhaust, the extra oil vapor would get burned up--and would make NASTY exhaust stains anywhere it touched.

Re: Walter - any theories on Oil Seps.

how about this, I made an arrangement with my wife to clean to bellyof the airplane.  beats the heck out of using an air-oil separator.  (Bad news is I get to rip out the rugs in three rooms.)

Re: Walter - any theories on Oil Seps.

Here's a smart man. He rips the rugs out once... she's gotta clean the belly forever?

Yeah, RIGHT.  Never met one yet who's that dumb.  <g>

You're gonna get the rugs ripped out and she's gonna think of a million reasons why she isn't going to clean the airplane--much less the belly.

We're guys.  We like to be TRICKED.  We're so good at it.

Re: Walter - any theories on Oil Seps.

exhaust stain is what got my belly dirty i guest.
that  longer muffler does the job almost no more cleaning since i instaled it ,even tough the 182 is a famous oil spitter if you load more than 8 quarts .
youll see many 182 s on paradrop operations in usa with muffler extension for the purpose of having much less washing to do and it works

WD-40...check Home Depot or Lowes....or similar first.  Grangers will charge about 50% more.   I saw the stuff at Home Depoe a couple of days ago.

Re: Walter - any theories on Oil Seps.

At the risk of appearing badly (since this question wasn't directed at me), and also at the risk of appearing to be on Walter's case,...which I'm not... I must say that Walter's position in agreement with "jk" to vent the crankcase blow-by into the exhaust system is an exceedingly bad idea.  Such a mod would result in exhaust-gas pressurizing the crankcase via the vent/oil seperator plumbing, and would not only introduce corrosive exhaust to the crankcase, but would likely result in blown prop-shaft seals, etc., and may even result in the total loss of oil while inflight.
  Don't do it.
  (And Dow-Corning's bathroom cleaner, "Scrubbing Bubbles" does an amazing job of removing exhaust stains.  I learned that trick from one of the pilot's on the Red Baron's pizza demonstration team.  Check it on an inconspicuous place on your paint however.)

<I must say that Walter's position in agreement with "jk" to vent the crankcase blow-by into the exhaust system is an exceedingly bad idea.>

I think you misread my post.  I DO NOT think that is a good idea to vent the crankcase vent into the exhaust either--for the same reasons you think it's a bad idea.  I was only stating that IF it were done, it would put a mess on the airplane as the exhaust would be *oily-sooty-yukky*.  How's that for scientific? <g> There are engine applications where that is done, but it can't back-pressure the system as there are check-valves.  In general, I don't like the concept.

As for Scrub n Bubbles, it's great stuff.  I've been using it on my Twin Beech and Bonanza for a long time with no detrimental effects as far as I can tell.  I also use it on the leading edges to remove bug guts.  Works well.  We have stainless plates on the Twin Beech where the exhaust comes out along the nacelles and we use Easy Off oven cleaner on the stainless.  DO NOT GET IT ON PAINT! When you own a Twin Beech, you get good at cleaning oil off--------or, you learn to live with a messy airplane. <g>

Re: Walter - any theories on Oil Seps.

Thank you for clarifying your statement.  I'm glad we found something we agree on! ;Þ
  There is an excellent commercial product available that is the "bomb" on messy bellies,....Hydrosolve,...by JetStream.  I highly recommend it.  Easy to use, and that bad stuff just dissolves away!  (Safe for airplanes, too.)
