You have had a ProCharger kit, blow a seal out? Or is this on another system, on a car thats had multiple issues? (Sorry for the confusion)
Seems odd how that much crank case pressure could be created to move a seal with the way we have it routed, we have measured (and collected) what comes out of the vent hoses on the dyno when we designed the system. (Basically making sure caping off the valley pan wouldn't change anything) It made no difference, so we moved forward with the current lay out.
Please keep us posted. As we will keep you all posted as well, if we have an in-house leak, or another customer of ours.
Thanks!

Well I might as well post up my catch can and its routing on this thread. I have several thousand mile on my boosted C7 and no problems so far. Basically how to read this is just match the colored dots to see where the ends of the hoses go.

It looks like we are all set also here... Just put a bunch of dyno passes on her and ran it out few times on the street. Venting the valley cover port, along with stepping up hose size (ETMC) on the valve covers seems we are good. We had good success with the valley cover vent, but we went forward with the 5/8" valve cover hose off driver to air box, 1/2" valve cover hose off psgr top to air box, mid psgr valve cover fitting to dry sump/aux dry sump tank, valley cover vent to independent filter.
Theta: Of course Bob
It was a pleasure for me at least working hand in hand with Bob for many years when I was at ECS. We have probably spoken 6+ hours on the phone over the weekend, he takes this kit very personally along with Doug/Chris/Alex/Shawn and the rest of the ECS crew. Everyone has been communicating to put this issue to rest.
Client is getting his car back tomorrow
