I started to do some small things getting ready for the major work this weekend.. One of those small things was swap pcv valve.. three minutes tops, right?

I have a volant cai the previous owner left me... I've opened it up a couple times to clean the filter, and that is about it. This was the case the other day- at what point I thought "self, wonder how old that pcv is?".. uh-oh..

Tonight I yanked that thing, and it disintegrated in my hand.. oops.. curious thing though- the thing has no innards.. it's a straight shot through with only the 90* elbow to slow anything down...

I put the new one in and went to push it into the CAI cap above the TB, and managed to push the grommet into the casing.. whoops.. three minute jobs suck you know..

disassemble the cai, and find the grommet resting on top of the TB (but not in, that was nice..) and then I think of that plenum kit in the garage..

I grab a flash light and precariously balance my extra large self in some dang yoga position or another to peer down the TB into the belly of the keg... and something curious again... huh, "Self" I declare " there ain't a dang drop of oil in that there thing, and I swear it appears to be aluminum in there.."...

three questions-

1. if the plenum isn't leaking, should I continue with the kit?

2. What possible advantage can there be by gutting the PCV? Is there harm running it that way? Will running a new one, after all this time, put the freak on the 'puter?

3. with a gutted PCV, why in the world- or HOW in the world can the inside of the keg be so clean?


(okay that was five questions- whoops- just like a three minute job it got carried away with itself) :-)

thanks in advance...

 

this has been pondered before if the after market pcv valve was sucking in oil and making it "look" like it was a blown plenum, who knows till you tear it apart , but fram failed and OE mopar still works in my case, as far as pcv valves......

 

You're yanking the wrong side.

 

explain... wrong side?


edited to add-

Oh, I get it.. you think because I spoke of the Volant's hat that I somehow pulled the wrong end of the hose and tried to cram a pcv in there... that's fair enough an assumption I guess.... Nope.. I pulled the entire hose off after breaking the pcv, because the barbed portion was still in the hose..

I pushed the grommet into the hat whilst I was trying to put the hose back on it..

This ain't my first rodeo... I may act dumb- and maybe I am about some things, but I've built more than one engine in my thirty eight years.. And I've enough sense to know which end of a hose a positive crank ventilation gizmo goes in.. :-)

 

The other valve cover.

 

now I'm showing my ignorance- the driver side valve cover was easy, and it goes to the throttle plate under the TB.. what the hell is the passenger side for? (which, incidentally had/has the same exact fitting, just gutted..) I've never seen two pcv's on an engine before, but I just shrugged it off and slapped it on there thinkin' it was another of those computer/emission mysteries I keep encountering.. :-)

that does it.. I'm buying the Haynes....

 

Just to make it short, the PCV goes into the intake manifold and the breather goes to your CAI.

 

to make it long. there is a hose coming off each valve cover.
the side that goes into the breather is a fresh air intake to the engine. the valve cover do-hicky is just a hollow elbow.
the side that goes into the intake should have the real pcv.

there is no advantage of having no pcv. its better to positive ventilation.

you can test your belly pan for aluminum vs steel with a long stick magnet. it would be a damn silly shame to remove the intake and find a perfectly good aluminum plate already there.

 

yes continue with the plenum repair, and do the kegger mod while you're at it (you'll thank yourself) but even if the plenum isnt blown now, it will be in a matter of time, theres no way around it, so get it done now, and then you wont have to worry about it again.....you got the Hughes or APS plenum kit right?

 

Never mind... others beat me to it...
