    I am enjoying this thread too! I have fitted one of Richard Good's separators on my supercharged fuel injected car. I also understand I have the hoses reversed but so far so Good. It's mounted near the battery and looks way out of place. The drain from the bottom of the separator goes goes continuously downhill to the fuel pump block off plate.

    What I want to learn about is the use of PCV valves on some of these installs. Didn't notice any in the photos of this thread but have seen some added in other TR6 photos. What PCV valve are being used? Most valves are designed to be used in a vertical position as the plunger seats by gravity. Most even havea number on the plunger that equates with weight or maybe vacuum? The ones I've see on TR6's are mounted horizontally and from what I understand horizontal PCV valves are spring loaded.

    Hoping the wisdom of the List will set me straight.

      Rick, the one Richard sent me is a V172 and appears to work only in the horizonal.
      I still haven't installed it.

        Hi Poolboy,
        What was the outcome on this thread, I recently fitted a PCV valve only to have it block up fairly quickly. This caused the oil to blow out the valve cover of my alloy cover and just about every other hole as well. I removed it again.
        I fitted it thinking I was doing the right thing, now not sure what is right???

          Hey Greg.
          Once I eliminated all the extraneous stuff and hooked the carbs up directly to the evacuation ports on the carbs all those related problems went away.
          I think the Goodparts PCV kit "T'd" into the brake servo vacuum hose might be good for those using carbs other than the original ZS carbs that had the provision for evacuating the crankcase pressure thru the valve cover vent.
          This is the way the Goodparts kit installs using "HIS" PCV valve, which I think is a must. There are different valves and not all are appropriate.

          Here is the way I cured the "Blowin Smoke" Blues with the engine that I was running when I started this topic.

          And here is the way I have the plumbing in my current engine:

          And here is the way a TR4 dealt with it:

          If you have ZS carbs, I think you should take advantage of the engineering that went into the design and utilize the evacuation ports on the carbs.
          Since you are having problems, connect the Valve Cover to both like I started out, as seen in this picture:

          Then if you manage to get things under control, you might see if just one carb will do the job..It might

            Thanks Ken,
            This last picture is the way I had it before I fitted the PCV valve, then had the vast oil leaks issues! I have now returned it to as before, I cleaned the engine, went for a good blast and it initially seems ok. I will keep you informed, now I need to find out why my nissan 200 diff wants to pump out the oil, I think I must have a blocked breather there as well!
            Thank you.
            Greg
