The third one, the Honda Accord EX - it looks to me like the straight pipe is the breather and the "Air Flow Tube" is manifold vacuum distribution...but I'd need a parts list and/or a pic of the actual intake snorkel/airbox to verify, even with the first pic showing the actual intake manifold and EGR system. Depending on where all those air flow tubes go, the Ron may not have capped the right vacuum source to achieve gains from his groove on that one. Any chance you can get a vacuum system schematic?
The Tacoma...looks to me like hose 12261 has the pcv valve at the bent end, so cap at the opposite end on the manifold, and then T-connect that hose into hose 12262....again, an intake snorkel/airbox diagram/parts list would be handy here to verify.
Sorry...this was the topic/issue we're looking to resolve, capping/rerouting PCV on these cars, right? I'd have to scroll back to the top of this thread to review...
