00VI PCV Valve setup
for those of you with the 00VI and using the 4th gen rear valve cover, how is your PCV valve setup?
if you have the part#'s and where you purchased from as well to get it to work that would be great as well. thanks.

I bought a 90 degree bend one and then hacked some height out of it, so it's about 2 or 3mm shorter than our normal one but still exits to the side. I don't know if it works yet, since I haven't done the manifold install, but judging by my measurements it SHOULD work. Up until now all I've been told is "don't bother, just modify the rear valve cover," so I'd be happy to see who else has done an actual normal PCV valve setup without modifying the cover.

If it isn't add some bulk to the circumference of the elbow by epoxying or siliconing the outside of it... something of that nature. The weight of the 00VI on top will keep it in place also.

i saw you post up about your pcv in another thread, correct? did you get it from advance auto or where?
and how is it holding together after you jb welded it?
i might have to do the same setup, unless i find something else or anybody else did something different.

When I compared the two I thought, "Hmmm, not sure if this is going to be short enough." So what I did was cut everything off from the base on up, then hacked the 90 degree bend/tube at the top off as one unit, then JB welded that nipple/bend at the top to the base overtop of the hole where the valve sticks out. So effectively what I did was remove length inbetween.
The valve has yet to be on my car, so I can't say for sure how well it works, but I didn't do anything to it other than remove length on the tube. I've pushed on the valve to make sure it can come out, and it still has 1mm or so clearance from the top of the tube. You can beat the living crap out of it though and it holds tight, the JB weld works nicely.

i've pulled mine out w/o removing the 4th gen upper. if you managed to have the pcv valve on below the 5th gen upper, i don't know how you would be able to remove it w/o removing the 5th gen upper, unless you have super powers.

I asked for one when I went to the store to see what it looked like (forgetting how the 00 rear valve cover is oriented) and it looks identical to a 4th gen.

dandy, where can you get this elbow from? is it a metal elbow? or hard rubber?
and about removing the pcv, entirely, how is it done and is it safe to do?
if it's safe to remove and easy to do, maybe i'll just do that, but finding an elbow doesn't seem like a bad idea either.

Oh crap I just realized I was mixing something up. For some reason - don't ask me why - I probably just read too quickly earlier (I was at work)... but I was thinking you were using an elbow as in a heater hose elbow or similar and not a 90° PCV valve. But now I see what you're doing... in that case your PCV would still be under the manifold.
I'm talking about getting an elbow.. just a plain 90° fitting, a hard plastic heater core type elbow for example, that will fit the grommet (or that can be reworked slightly to fit) and then run a hose out from that to the PCV valve.
Sorry for all the confusion.

ya, getting rid of the pcv would be nice, wouldn't it? but then again, if it's safe to do, that's news to me.
dandy, where exactly did you get the hard plastic elbow from? an auto parts store or a hardware store? if i go that route, it would probably be best to take my pcv valve in and get an elbow of the same outer diameter, huh?
thanks.

When I was test fitting the upper I forgot to remove the PCV and ended up cracking it off. It left the nice rubber piece in the valve cover and part of the plastic of the PCV but everything was flush with the top of the valve cover. So I just inserted a piece of hose down inside the remaining opening of the PCV, snug fit, and ran the length of hose leaving the other end open. Seems to be working fine, not dumping any remnants of oil anywhere & I assume it's getting the required ventilation when needed.

that is interesting.
i think i'm going to try dandy's suggestion and find an elbow w/ the same outer diameter as the pcv valve.
so nobody has found a pcv valve that is a direct swap huh? that's unfortunate.

Are you asking so you know what size of valve to buy, or a fitting to replace the valve in the valve cover? Just go to any parts store and ask for the proper valve (00+ if you're using inline or a 5th gen rear valve cover) or just use like a 3/8" fitting if you're replacing it with an elbow or something.

Have you thought about a catch tank...
I,m currently running a 90 degrees elbow with a single hose that get in the driver fenderwell directed to the ground. It stinks on stoplights but don't pollute my engine internals. In quebec, we don't have smog tests...

wow, way to bring back an old thread. i had a pic somewhere of the pcv valve clearance issues w/ the 5g upper even after i hacked the valve. i don't know where it went though.
i ended up going w/ the 5th gen rear valve cover.
