I know this is a pretty old thread, but hoping someone might still be listening. I suspect I might have an issue with the PCV system I rigged up on my ModMan intake. It has some tiny 1/8" NPT ports for the breather similar to the Mopar manifold, but I had no idea what valve to use. I grabbed something from the parts store for a similar sized engine thinking that might be a good start, but I'd be curious to see what the original Mopar kit looked like if anyone has pictures or part numbers. I would like to use something more like an inline valve, but wasn't sure how they might work as I believe a lot of valves are orientation specific and require gravity for them to close properly. Would be nice to know what valve was included with the Mopar kit to see if I could adapt it to my setup.
