Bad Stuff happens on a 2015 Traverse when the PCV valve hose is off

First the engine runs erratic, the right radiator fan comes on,backfires, engine dies after a few minutes, and last but not least, 15 codes are set.


The little throttle body computer really gets screwed up. Don't know if it's "to rich,to lean, to much air,to little air,etc., etc."



Why oh Why would anyone pull the hose off the pcv valve and start the engine someone screams?


Doing routine mantenance , after 6 to 7 hours, using almost every tool I own and could borrow, the stupid valve is still in the hole, correction, the bottom half is still in the hole, correction, half of the bottom half is still in the hole. Will not budge. Used vise grips, channel locks, regular pliers, 17 in. pry tool, 4 foot crow bar, screwed a self tapping bolt down in the hole in the brass ring in the middle of the valve and froze it with R12 and tried to pry it out...........ITS STILL IN THERE.


Temporary solution,plugged the hole in the broken valve, put a new valve,Standard part# V518, in the hose, zip tied the pcv valve hose to some hose running along side it, and cleared the codes.



Runs like a brand new one.



Will take it down to Ernie's Tire & Auto in the morning, put it on a lift and do a number on it.

"An easy out"?........Good thought;



In the middle of the valve there is a "brass ring" with a hole that appears about the size of the hole in the top of the valve, could be a "touch" bigger.



Problem, the little "ring" broke loose & just spins inside the valve.

What a mess... this is why I haven't touched my PCV valve yet, on a 100,000 mile vehicle little 30 minute checks can become expensive, weekend long ordeals.

Since I got my Traverse I have been keeping an eye on the oil level. I'm at 60% remaining and my oil level is still at the max line, so hopefully there are no PCV issues currently. I may start giving the PCV a blast of PB blaster or the like at each oil change to try and prevent the seizing you are experiencing.

Been all over the net, U tube, etc.


Nobody has had a seized valve..............Why Me??


Answer............Why Knot.


But, that thing is coming outta there even if I gotta put a torch on it........and I gotta half a mind to do it.


The BW...IE: Beautiful Wife agrees.........I gotta half a mind.

I used pliers on mine. and gently turn left and right while applying upward force.


It did have what appears to be thread locker on it.... red.


looking at some of the pics in this thread- you can see the red stuff.

Am sure U saw the difference between the OE valve & the auto part valve. So, that tells me that quite a bit of the bottom half of the valve is still in the hole.


Have used every tool I have ,almost, and it wont even turn, the small upper half is twisted off and the bottom part sticking out is all twisted up. Will show pictures....if I can.


Also, have WD 40ed it, froze it,etc. Wont budge.


Gonna get a hammer & cold chisel.......it's coming out, one way or another.


And also, the new valve is gonna have about 5 pounds of anti seize grease on it.


Why did GM do this...(A rhetorical question) First GM I've had in 30 years.........most probably the last.

Seriously,,don't waste your time since the PCV is broken. You CAN'T buy just the OE PCV valve from the dealership, there isn't even a part number for it. You need to purchase the ENTIRE valve cover which has the PCV pre-installed (~$200)

The V518 aftermarket PCV won't fit in the valve cover, it's too big. I guess you should take a hammer and dent the #518, but then you just wind up with air leaks and rough idle.
