Today I installed the BSH PCV Stage 2 kit, which is the stage 1 plus a catch can. I had the Stage 1 before but after seeing pictures of valves getting gunked up in this type of engine I decided this was good preventive maintenance item.
The purpose of the catch can is to gather all the small amount of oil that enters the PCV system and catch it before it gets back into the engine. The catch can will need to be checked each time I get the oil changed.
Install was very easy just like the Stage 1 kit, again the hardest thing to do is remove that blasted engine cover. The kit looks like it belongs in the engine bay which is very important to me. Im not one for chrome, red, blue or other colors that stick out. Here what it looks like:
