My difficulty at the moment is engineering in a PCV system with the Webers off of a vacuum manifold.
There isn't enough volume of vacuum left to pressurize the brake booster. Just getting the PCV system to work means finagling with internal restrictions in the line to the pcv and loosing 2 in-hg at idle.
Problem is there are no pcv valves that close 100% at idle. They are all open a little.
Doug, check out this product, http://mewagner.com
I also did not want to bleed off vac at idle because I have a large duration cam and I cannot find a "performance" pcv. I have bought quite a few, some have just a small hole and are rated at different vac levels. There are also people who threaded a screw on the top of a regular pcv valve to adjust it. I bought one of these valves but because of the cold weather and bolting on other parts, I am not sure when I will get to test it. Try it risk free for 30 days and you can get an inline adapter and it can be mounted in any direction / orientation.
