M8 Turbo Oil Tank Vent Idea. Thoughts?

[dirtsnow]

I have an 09 M8T with a non vented oil tank. I've been thinking of ideas to vent it for obvious reasons and suddenly i remembered plumbing my boiler in my house and the automatic air vent i used to get air out of the system. Can anyone come up with any idea as to why one of these wouldn't work great? They have a float inside so that when turned upside down or fluid hits them, it closes the valve. I think it would work perfectly! Give me your thoughts.

What are the obvious reasons to vent the tank ? I designed and fabed a tank that will not spill on a roll over that is vented but I'm not totally sure that with the pressure that builds in the tank That a vent is needed.

Going up in elevation and increasing the temperature will cause the pressure in the tank to increase which then causes oil to blow out of the seals. If you are able to equalize the pressure, you can prevent an oily mess in/around the tank and keep from losing oil. The system would stay much more contained.

I was just looking for easy ideas on how to vent it because this automatic air vent is the only good idea i can come up with. I'll have to weld to the tank, but i don't see another good option.

You can buy a vented cap from bungking.com

Most all turbos are designed to blow some boost out the oil return this is to help extract the oil out of them. If you are making 10 # of boost you will have 10psi in a unvented oil tank.

This cap is a 100mb so it releases pressure at 1.4psi

Up in till this year all the tanks I have built for 2-smokers have been unvented. They have been the type were the turbo is perched directly over top of the tank. Always seem to leek a little around the o-ring seal from the tank to the perch. This style of tank you can run unvented with a ball bearing turbo but I would not do it if you are running a micro pump

Have any of you used a vented cap? Boyko, will that cap you linked to work well? Won't it melt because its so close to the turbine housing?

If i threaded one of these into the filler cap, would it leak when i have the sled turned upside down rolling it out of the snow? Has anyone used one of these? What's your personal experience with these vented caps?

I'm using one on mine. I will snap a pic and post it when I get home tomorrow. I used that vent and put a vent hose to a catch can to stop some of the mess from the blow through.
