calpoly-z Posted October 24, 2008 Share Posted October 24, 2008 In the process of putting my motor back together after warping the head, and now I'm dealing with what to do with the PCV now that I have switched to a N47 intake manifold. I shaved most of the manifold, but decided to keep the EGR flange to save myself a bit of effort. I knew that the PCV valve would hit on my turbo with this manifold so I started playing around with alternatives. The simplest solution I discovered was that the PCV valve screwed directly into the bottom of the EGR port. Now I'm running an aftermarket DP so EGR is not used and this port would just have to be blocked off anyway. At first I thought about just keeping the EGR valve there and hooking it up to the manifold since it would only open under vacuum, but then I decided I didn't like the way it looked. I found an old EGR valve laying around and decided to see if I could just use the base of it and take the valve completely out. So far it looks to me like it will work great. There were a couple of small holes that I welded shut and then I powdercoated the thing to match the intake manifold. Here are a few pics of how it turned out. So does anyone forsee any problems with this? I only drilled out the EGR valve to 3/8 since that was the biggest drill bit I had handy, but the orifice in the PCV valve is about that size too if not smaller, so I don't really see any flow restriction issues. The biggest issue I think will be routing the hose that close to the hot exhaust housing and downpipe, but I think I can can keep it far enough away. Any and all comments/suggestions are appreciated.
