Has anyone considered installing the oil catch can over the exhaust manifold? This should help reduce water condensation and also melt any accumulated water in the can.
It is the owners responsibility to maintain the aftermarket part, don't install an OCC if you're not going to monitor it. It would be a nice feature to have a pressure relief valve built into the OCC (to save the valve cover and throw a code), but still it is the owner's problem to watch it.

I just passed 102,000 miles without a catch can, or needing to empty one.
Imagine that?
Yeah... I wouldn't recommend my grandma getting one either!

New upcoming mods to my catch can. Going to install it horizontally. Nice that this thread contains the how to access the top hats as I'll need to get into that area to setup the mount for my can. Still trying to find the best prices on the parts (just noticed I picked out the wrong size fitting for the brass reducer). May get things locally.
I tapped the 1/8" hole to 3/8" for a sight glass (B) instead of the PTC clear hose setup they had originally.
The vacuum gauge (A) should let me know if something is wrong????? If not it will look neat.
I will have a baffle to protect the gauge port and a K&N breather filter w/ 5/8" ID inside the catch can on the line that goes to the turbo.

You WANT to get the water out of the system! In an ideal world, you'd have the catch can directly in cool airflow to increase this effect.

I just got one like this too under the name "Ruien" on amazon. I like how it has a little basket for condensing media which I filled with some beaded chain.
Two minor things I don't like:
1) It's painted and not anodized which might not stand up to oil/fuel exposure. This also made removing and opening the basket difficult since it was assembled while not fully dry.
2) The dipstick doesn't have an o-ring and could be a potential vacuum leak. Easily fixed with a rubber washer.

-10an fittings and 3/8" hose is what I used, but is very tight getting the hose on the pcv plastic fittings. If I was to redo my setup, I would def go with -12an fittings and 1/2" hose.
You can see my setup in an earlier post in this thread.

do NOT buy straight silicone hose. Oil will damage them. You want fuel/oil rated hoses. These are special silicone mixes with a lining.

I didn't see anything in previous posts (I'm a skimmer, I admit it!) but How does this hook up using the PVC modded intake, how does it hook in?

Most existing catchcans installed by members here are plumbed into the boost (external) PCV system that connects the top of the intake to the turbo inlet.
I haven't seen anyone use one on the vacuum (internal) PCV system yet since there was no way to connect to it until the intake mod became a thing.
