Roll over valves

[waynehartwig]

I was just thinking... Why could one not use a PCV (or any other one way style valve) valve as a roll over valve?

...Think about it, they are very common, cheap, etc...etc...

...Or are others using them already and I'm just not in the 'know'....

Well, actual rollover valves are pretty cheap as well. I see no reason not to use an actual rollover valve. Even if the valve went bad (got stuck) while on a run, the worse that would happen is you'd have to pull it out and you may leak if you rolled. Not a huge deal since it getting stuck is not very likely in the first place.

Oh, and to add a little more, the only real issue I could see with using just any old one way valve is if it has a plastic ball or plastic parts, the gas/plastic combo may not be a good thing. Some plastics may not be affected but as I'm sure you're aware, some will just dissolve.

Caleb - do you have a local source on roll over valves? I need to make my rig safer.

Yes! Summit Racing may as well be local, since most orders show up the next day.

Summit would be my suggestion as well, if you really want somewhere local I bet Evco on 3rd West would have some since they have lots of the Earls stuff.

I'm not sure where you are buying your PCV valves, but I just looked on Summit and I didn't see a roll over valve under $20.

I also looked under Earls, and I don't see anything there at all.

So post up a link!

I'm not saying a rollover valve is as cheap as a PCV valve but I am saying they aren't THAT expensive. There are several on Summit for <$20 Link. I'd rather use a part that was designed for this specifc use when it's as cheap as they are. I can see if they were pricey ($100+) but for $14 vs. $5-$10 I'd rather pay the few extra and not skimp on it.

A rollover valve is not a "one way valve". A rollover valve will actually let air, fuel, rain, whatever in AND out, as long as it is right side up. When it's upside down a little ball actually falls in it and blocks the opening. They're not prohibitively expensive. Use the real thing.

Right, same as a PCV valve.

The main reason for starting this thread was for oil control, not fuel. Diff/tranny/tcase breathers for example...

a pcv valve will not work in that manner. it is open in the up position as it would be that when when you roll . it seals off in the down position.as it is used on the motor the vacum is sucking in up which is opening it.

I know that my life isnt worth 15 dollars Wayne, I'd use the PCV valve What do I know I run propane

And you drive a sami, which makes it even less.....maybe negative

Did you ever come to a conclusion if this would work, I need to vent my tranny cause it leaked bad when i rolled last year?

I'd suggest those balloon vent things that most the comp guys are using for Diffs, trannies, etc.

I need more info on those balloon vent things. Where would I find them? Thanks.
