2012 AK sled build

The only problem with the rollover valve is that the tether needs to be pulled. I rolled my sled over on Monday(with me half pinned) and it was WFO for about 4-5 seconds before I could pull my tether. I lost a lot of oil and a properly functioning oil catch system would have worked perfect.

Maybe you should make your sled lighter!!!!! LOL

Very creative, I'm sure I'm missing something, but how will your design work better than a rollover valve?

Well the picture is just a really rough drawing of the idea, but the concept is to keep oil in the tank during a rollover without the need for a power source. Even though I strongly recommend wearing a tether all the time. There are instances like hyflr's video were you cannot shut it down with a tether in time. That's when a catch tank breather would be handy.
 
I was thinking something like this combined with a tether of course.
the breather makes a loop down to the bottom and up to the top with breathing space at about the diameter of the tube.

its the middle of the night here so i blame my Paint skills on that :drink:

Edited as apparently I misunderstand the inner workings of an ROV. Carry on. Nothing to see here.
 
I Have had some problems with my org tank.. The first race this year with the K&N filters i lost my brake because the oil had escaped through the filter, i ran the next with just a Coce bottle to capture the oil..

This is my idea to fix the problem, What do you Think?

The plate with holes to vent the tank and cause the oil to get up to the filter
And then a return back to the org tank

Can't return the oil to the oem tank. The oem has a air seperator and filter. I cut apart my old tank yesterday, I'll post pics Monday.
 
I dont believe the oil would go back into the tankn unles ur catch tank was mounted higher than the original tank. It would just sit there due to a higher static head in the original tank. You would also need a check valve on the bottom line because pressures would equalize between the two tanks.
 
Ok, then just use it like a Catch tank with no return.. I Think the plate must be there otherwise the oil going to escape through the filter again. At normal driving i dont have any problems but on the track i have about 0.05 gallon oil in my coce bottle after 3 laps at a 450 meters track
 
CR Racing is working on a valve that is unlike the current selediod operated valves. It will be a billet aluminum part and just non mechanically close when rolled over. He doesn't have it ready yet. Nor have I seen it nor do I know much about it, just another option.
 
The ROV currently sold are garbage and i would caution anyone from useing them, if your sled spends any time on its side or upside down. It was one of the first mod i did and it was the first thing i ditched after a few rides.
One they don't hold oil back after a few hundred miles because they condensate and gum up, thus hangup and the oil just runs out.
Two they cause engine runnability issues.
Now i use a combination of ingenious hose routing and catch tank, have been for two seasons with ZERO oil issue. I have done the same with my cooling system, as coolant would also pour out when i rolled.

So post up some pics of this and save the rest of us from the headaches we all are dealing with!
