Have a fp bb on a 9. Jeeps leaking at the housing. Tried a stm sealed catch can and a vented one and still have issues. I know others have had issues trying to see if anyone has fixed it..

it has the purple fp feed from the head

 

What did Forced Performance say about it?

 

waiting on a reply.

 

If its pre 2020 Its super sensitive to oil pressure and crankcase pressure. Better off getting a newer one.

If you have a -10 line from the crankcase for vent to a recirculated can it can help. If the engine is super loose it might not be ideal. You can also try an adjustable turbosmart regulator and cut oil pressure down to it. At start up with thick oil it gets too much oil and gets pissed. I'm using an older version with a cut spring and washers to achieve 10-15psi at WOT when oil is 180* IIRC.

I've got a 2020+ xona chra BB red with a regulator and 10-40 oil. If I don't let it warm up a bit it will move a very small amount of oil vapor . Other then that its fine.

 

Are you also using the purple 0.020" restrictor? is your regulator before the restrictor?

 

Restrictor is after the regulator. Pretty sure its the .020
