Posted: Mon Jun 04, 2007 9:10 am Post subject: Breather run into exhaust

I was wondering if anyone ran their breather tube into the exhaust. I have seen this done more and more lately on aerobatic planes where the breather runs into exhaust. Granted they have some separation from direct crankcase breathing vie the inverted systems but vent none the less into the exhaust. Any thoughts?   

   

Thanks

IF it is done correctly, then you  create a vacuum in the crankcase which in turn reduces windage losses and  therefore increases Horsepower. The exhaust system becomes your venturi  to create the vacuum, while at the same time burning the oil vapor  coming our of the breather.   do not archive

I fly mostly aerobatics in my RV with inverted oil system.  I vent 

into exhaust and I never had any problems.

I have a Sonerai with a breather run out the tail.  The builder put a

bulkhead fitting with hose barb ends in the firewall and ran a plastic tube

all the way through the fusalage and has it coming out right over the

tailwheel.  You just plug the breather tube from the engine into the fitting

on the firewall and the oily belly problem is gone forever.  I really like

the setup and will put it in on all my future planes.  It is easy to do,

effective, and adds very little cost or weight.

Mike, exhaust venting is the way to go for a clean belly. There are several kits available to do this. Mr Gasket comes to mind and I use that one, it comes with a steel check valve to prevent any blowback into the crankcase. The kit comes with two of them but I only use one in my applications so I have a spare. It's yours for the cost of freight, probably 5 bucks or so.  Contact me at my web site if interested..

I like the idea of venting into exhaust.   Where can I get a kit?

I exit my breather exhaust within about an inch of my exhaust pipe but 

still get an oily belly.  Does this system directly tie into the exhaust? 



I also disconnected the return line from the seperator to the oil fill 

and ran it to the other exhaust.  I dont think I need the few drops of 

sludge going back into my engine.

I have run the crankcase vent line  ONTO  not  INTO   the exhaust pipe on both or our  150 HP  RV-4's and don't have a  problem with oily belly.   About 1/8"  between vent tube and  exhaust pipe.

Is this the kit your talking about?  Got a photo

of how you plumbed it into the exhaust?

there is positive pressure in the crank  case if you can neutralize that pressure the internal rotating parts will  spin free ... resulting in free horse power. the exhaust can create a lot  of suction and actually suck oil from the crank case ... be careful.

     on a pumped up / modified I0-360 with a 4 into 1  exhaust i used a stainless 1/2 in tube welded into the collector at 45 degree  angle ... plus ... a metered  'pill' to get the correct vacuum pressure. i  monitored oil consumption changing the orifice size until oil consumption was  normal. the house power increase was the most notable of all previous  mods.

     yes ... a poor mans smoke system but no more oil on  the belly ... do it! lots of acro guys do ...

Mr Gasket has one in the Jegs catalog. Part #  720-6002. I am sure Summit racing sells them also. Don't tell them its for a plane,, just say its a "off road vehicle"  <G>

It is very simple , just connect your vent line that in presently being dumped overboard to the valve thats fastened to the exhaust pipe. The concept is this, as the exhaust gas passes over the end of the little pipe thats in the tailpipe it causes suction, just like those parts cleaners that connect to a high pressure air line and have another hose that goes into a can of solvent.  With the crankcase evacuation system the faster the motor revs, the greater the exhaust speed is and the greater the suction, which is perfect because the higher the motor revs the greater the blow by.

I havent hooked up my inverted oil system yet.  Would this system work 

with the inverted system?

The collector is where al the exhaust pipes merge together and  usually the tailpipe is connected to it. It is also the place in the exhaust system where the exhaust gasses are flowing the fastest, thus giving the best results for maximum suction. As for your inverted system, my guess is that the engine crackcase needs to breath so it won't blow out the crank seal, I would assume the crack ventalation system is the same for normal and inverted engines. Any one else want to chime in to either comfirm or refute???

Jeff,

 Why do you have an oil separator if  you don't reuse the oil in the first place. What is the purpose of  separating the oily air mix and then discard both onto the  exhaust pipe???  I'd remove the weight of the useless  contraption...
