    PCV Pipe clogged?....

    2007 WRX TR. 40k miles. routine oil changes at/around 3000-4500. (depending on long travels) minor mods that pertains to the engine bay. spt intake w/ h/s, Sti i/c, engine grounding.

    so, last night i found a little something that isnt suppose to be. i was using the DIY grounding kit. btw that came out great. that wasnt the problem though. when i was installing one of the grounds, a connecting hose to the PCV pipe was oily so i decided to disconnect and inspect for the heck of it. well, i found the almost the whole thing clogged.

    im just wondering whats the reason for this... another thing is i have a catch can in hand. been skeptical about installing. i think if i install i would prevent this from happening. well, well see what everybody says on this because im totally confused. thanks in advance. first thing in the morning ill be cleaning them out one by one. and ill be in time for HIN in Scranton, PA. (im not going to be showing though)

    so, i cleaned the PCV piping this morning and cleaned it out thoroughly. majority of the crap that came out was all emulsified... (some goo goo ga ga in the dipaers kind of thing. lol) anyways i took off the left hand vent it was clear then took off right hand vent. now that one was crudded to a certain point. it builded up on corners of the tubing. inspected the intake piping to the turbo. a little dirty not too much to mess up things, so i went ahead and cleaned it up.

    i test drove afterwards, and may have noticed a change. dont know how to describe it. the engine can now breathe better. most def it can.

    an addition to the emulsified oil in the piping and tubing. engine oil is normal. no contamination and normal sump level. (but that doesnt preclude me from checking routinely.)

    Wow, I pulled that tube off a couple times, never had anything like that (just a little black sticky oil).

    You might want to ask a Subaru Tech

    emulsification , water or lots and lots and lots of condensation.
    on the back right hand side of ur engine there is a nipple coming off the c/head i have seen in the past people re plumbing the oil breather lines for the crank and c/head oil breathers off this nipple when it is actually a water line fir the idle controll valve , sounds very stupid but has been done , dont know if they thought that it was an oil line as when u pull it off the icv some times theres water and oil mixed together and basically they think that the lines that go to the pcv , throttle body , turbo inlet etc for the oil blow-by are also going to the icv when its actually water but always has traces of oil in it? anyways, not saying its that but i had 2 re-plumb my mates catch cans as the previous owner hooked the blow-by lines up to this nipple and it looked a bit like yours , not as bad but very similar , to cut a long story short u have water or very very bad condensation in there and u need to find out pronto where its coming from as all you will do is take in the emulsified oil (which is bad enough) through the intake via the pcv , the one bonus is u have the catch cans so... shouldnt be that brutal but as i said fid the leak or wherever the water is presenting itsself into the blow-by system (positive crankcase pressure system )

    ya, but i would still need to clean the pipes and hoses as well when i change the pcv valve, would you just pull off the hoses and piping and spray water in them and scrub the inside with a pipecleaner to get the gunk out of the pipes then wait till they've dried and put everything back together?
