On the factory valve cover, the PCV exits are at the rear side of the cover. These being on the top, is there enough room to clear a factory top cover if one desires to run that?

Yes you are correct if you would really wanted to .I would imagine with this VC if you really wanted to keep a stock style PCV you could. You'd be running a -10 to barb fitting or similar and then just run your flapper and PCV valve in-line. The flapper might not look the prettiest sitting in the middle of a line, but I'm sure you could either tuck it behind the engine somewhere or put it towards the end of the hose.
My main question regarding the PCV system was whether or not we could take the easy route and run one of each fitting like pictures, but that was answered in another post from @m18performance when they said that its bypassing the entire stock style PCV system for two-10 outlets - i.e. no, we'll have to be more creative than just using a straight breather and the Radium pcv valve if we want low/high side separation but that's easy enough imo.
Can we get verification that it works with 90 degree fittings? If that's possible it would be helpful.

What fittings/hoses/components (external pcv, flapper valve, etc.) would you suggest be used with this valve cover, either VTA or with catch cans?
Thanks. Neil
I imagine it has to not have head ports - there is no internal PCV-related apparatus.
Filippo
If I ever remove my valve cover I would plug the head ports but let's say if running a vtt cap breather,is it safe to say that capping the ports may not be needed?In one of the first replies, M18 specifically states that they recommend blocking the ports off in the cylinder head. Also, if you look at the images of the VC, there are no ports drilled into the M18 VC. They recommend plugging the head ports to prevent higher boost getting into that small cavity/space in the stock VC gasket to help prevent gasket failures.
Yes its easy , just make sure you drill and tap not just insert a tap in to uneven cast hole.
Sorry for the crapy video
Whats the negative side of tapping this way ? Longer thread and longer screws holds better ? and not breaking the tap ?My $.02 is to don't tap like this video.
A minor hand tap using 10-32 plugs works very nicely (no pre-drilling is required). You only have to tap down just over 1/4" and use stubby plugs (we use 3/16" length 10-32 plugs). Anyway there is no need to tap all the way through or even remotely deep down for any reason, and having threads only far enough down allow the 10-32 set screw plugs to bottom out on the non-tapped portion of the port... an installed plug at flush or slightly below the head surface is fine.

I did mine this way and it worked out fine, no drilling required. Having more threads deep or a longer fastener really does not matter especially if you use loctite or RTV on the the threads, they are not going to back out. I used loctite on the plug and then a dab of RTV on top. Belt and suspenders. The RTV had a few threads to engage in so I am sure it is not going anywhere.
The only issue I can see with the video method is your are going to generate more metal bits, chips, cuttings, shavings, etc. when you drill vs. just using the hand tap. When I hand tapped very very little.
You right I just wanted to share maybe its over kill but im running 37psi+ did not want to relay on 2 rows of thread and some locktite . Did not have problem with shavings falling in.Hundreds of ways to skin a cat. Some will say, JB Weld. Some TIG. Some hammer and nails. Some full length screws. After dealing with questions/concerns with customers for several years on this, most will not be comfortable with that mess into the intake ports and some will be looking for ways around it especially if they don't want to remove the intake. Lots of OCD in this community, usually in the forum lurker crowd, just saying the way we suggest is the cleanest method to do it... and very easy and effective and takes only a few minutes per port. Not trying to argue but this suggestion could save M18 tons of emails going forward, so take it FWIW.
