Message	I have the PDV reroute pretty much the same way as in the FAQ except the I have two small filters on the vent tubes next to the TB. And the hoses run through a Cusco catch can. The other day my TB got stuck wide open after boosting. Turned out the metal valve cover vent tube got blown out under boost and got in the way of TB closing. I've since welded the tube to the cover. But why does the crank case have so much pressure under boost that the vent tubes can't deal with? I do have a bit of smoke under boost.
