I get a lot of oil all over my trailer and back gate on my bus. I've steam cleaned the motor and it seems it is coming mostly from the puke tubes.
Has any one fabricated a catch can that all the tubes can run into and then be drained every time you fuel up. in my case every 1000 miles or so. My thoughts were to fabricate a box that would hold a couple gallons with a breather tube and filter on top side and a petcock on the bottom. run rubber hoses from the puke tubes into the container. I get a lot of oil on rear bulk head from top of motor also but apears to be from another motor vent. |

I did that for my 8V92. I used a tall coffee can, ran a wire through the rubber tube and hung the can so the tube was about 2 or 3" from the bottom.
After a while I just took the can off because even when I checked them at each oil change, there wasn't enough in the can to make it worth while. I just extended the tubes down to about 6" off the pavement. |

Ron,
Mine are routed thru a check valve back into the crankcase. I know this is controversial but it works and GM even offers a kit to do it on upright engines. There are pictures in the files section of the GM Busnuts group that show my installation.

If ure loosing enough oil thru the airbox drains that u think u need to empty the collector every 1000 miles, then I'm thinking that you need some engine work. Remember, the airbox only emits oil during idle, not at engine speed
DD has had various solutions to collecting this usually minimal amount of oil, including the one Jerry mentions. My 6v92 lay-over engine is equipped as he describes. It also blows oil, from a leak in the rear gear housing gasket, which ends up on the back and towed. After repairing the main leak back there, the oil loss is minimal |

I am almost ashamed to admit it, but I solved my problem by a little wire and two old milk jugs! I just hung them so the tube went into the milk jug a short ways, the jugs allowed you to see at a glance how much was in there. In many years of use, I never had to empty one, so little is actually blown out the tubes. (Real cheap to fix if a milk jug goes to heck on you too) A friend made one that looks just like the DD one, out of a piece of PVC pipe, 4 inch or so about a foot long. Real easy, cheap, and just as effective as the DD one. |

My 6V92 In my 1981 mci use to blow oil out of the left side and less out the right side. On high idle the right side check valve closed and
the left side was blowing twice the air. I removed both the check valves and took them apart and cleaned them put them back on and started the engine at idle equal air was flowing out.
then at high idle no air from eather side is blowing out and the engine is running better on high idle and has more power. |

"Remember, the airbox only emits oil during idle, not at engine speed"
This is the 2nd time I heard this . Qoustion do they have some type of check valve? or somthing to stop high amounts of air?
Why could I not just block them off would the oil end up being burned in the cyl any way?
