Soooooo any ideas why my airbox filled with oil?

[Sheetmetalfab]

All of a sudden my talon started blowing smoke and about a quart ran out of the airbox when I opened it.

Are you overfilled?
Have you checked correctly. NOT screwing in the dip stick with proper warm-up and sit times?

lol... I saw your user name.. I'm sure you have.
Have you flipped it recently or anything?

Check valve on top of the head.
But I don't see any procedure for checking its operations in the service manual.

There's a crankcase breather hose (#6) venting into the airbox, shown in the service manual Page 7-16. It's hidden from sight, above the throttle bodies and it looks like the airbox has to be loose before you can get to it..

So far I found a torn r2c filter……..

trash that thing right now...
Post some pics in the other thread if you would, please.

The filter element itself or the composite around it? Not sure if you've seen it, there have been some R2C failures but it's the composite, not the element itself. Highpocket has a thread going on it.

Yikes.

Oh _rap! Guessing lots of abrasive taking out the rings, pressurizing crankcase and blowing oil out the breather hose??

Bad news! Sorry.

And I'd been thinking about getting an R2C after reviewing specs. Glad I waited.

Yep that’s my assumption.
will do a leak down test to confirm.

The amount of force (suction) to tear and pull in the membrane must have been considerable. I'm wondering if filter membrane blockage increased to the point that overcame the strength of the membrane. What does the other side of the filter look like? How many miles on the filter?

400 miles on filter.

That's not many. Certainly not enough to block the membrane. I just installed V2 of the R2C filter and will check routinely plus I will be installing a prefilter. It sounds like you had no indicators before it went catastrophic. I hope this turns out the least amount of painful for you.

We are talking about the new R2C filter that has failed early on after initial distribution, right? The cause of those failures being due to the potting, or sealant material that bonds the filter media edges to the frame breaking down or coming loose.

Oops, sorry. I was thinking you were dealing with the new R2C for the Pioneer, and you are dealing with the Talon version. Disregard my post.

Yes, I'm calling them V1 or built before 8/11/2021. V2 built after that date. The only way to tell is if you receive a new gasket and the shipping date on the invoice since there is no stamp on the V2 filter.

No idea why it filled with oil but I just installed a crankcase vent assembly to stop my engine from sucking in hot dirty crankcase air......

I'm also having second thoughts about the R2C filter I ordered. How the hell does that filter have more area than stock? Guess I should have paid more attention....
