No Twrx7 you don't seem to understand the Provent 100 specifications.Finally, you’ve made two big claims about the setups and how it should be in relation to the PCV/DCV that are polar to each other. You then went and pulled out the lids by pass valve, which as can be seen in the start of this thread with my case comes into effect when the filter is blocked up and not flowing, so is a good and necessary item to have. I’m not convinced that you have a true and accurate understanding of how it all operates together.
The Provent 100 and clones thereof are opposite to the 200. The depression valve is in the lid and the bypass valve is on the side of the body.
To be clear .THERE ARE 2 valves. ONE DEPESSION VALVE UNDER THE LID AND BYPASS VALVE IN THE SIDE.
The fact that the bypass valve has never activated suggests to me that the flow is sufficient.
Second, I cannot find anywhere the depression specifications of a Provent 100 or 200. At what manifold depression do they activate compared to the standard depression valve? Is it much higher therefore useless or is it much lower therefore increasing crankcase pressure or what?
Surely the LR fitted and designed valve is correct for the engine.
It seems to me that those who run 2 depression valves or only the Provent valve don't have a clue about what the effect is. So I suggest that perhaps you should do some testing with vacuum gauges etc to see what is really happening.
I am also touched by your concern for Mann Hummel. If they choose to price so high and make a **** design with the 100 which needs some ridiculous plumbing , having the inlet pipe as part of the mount, they deserve all the copies they get. I would have bought a 100 if it had the same inlet and outlet setup as the clones.

BTW I have not "taken advice " from Shonky sellers. some of the sellers like Western Filters are filtration specialists , and they do kits for trucks etc and do Provent 100 kits for larger engines than TD5s, where they have invested in engineered bracketry and sell for fabulous sums. I think you can be sure they would soon withdraw the product if they had numerous complaints.
