Catch can hose collapse?

[ThePresidential]

About 2 months after i installed catch cans on both sides, only the hoses on the pcv side collapse with the engine running. I have a breather on the oil cap so it still gets rid of pressure. My guess is i need a new oil separator and or valve cover on the pcv side because theres no blockage that i could find from the manifold to the pcv valve?

Does anyone know the reason why the hoses would collapse?

What happens when you put your normal Oil fill cover back on ?

CCs full or plugged ?

Theres no blockage in any hoses or cans, the can is barely 1/4 full, unless the hoses are collapsing because of heat soak and the bend in them is weakening them. I might try new hoses and placing the catch can somewhere else where the hoses dont bend.

Was that a kit from a reputable company? I'd start with replacing the hoses.


Has it always done that since you installed?

It just started to do this after about 2 months. The other catch can i have installed on the clean side is fine and the hoses dont collapse, those hoses dont have any forced bends in them either.

Im gonna try new hoses and re route them first and throw some heat shield on em.

Funny thing is after prolonged periods of idling then driving smoke would come out the exhaust for a lil. Since the hoses collapsed it hasnt  smoked once.
