PCV valve replacement

[BuickMike231]

Hey guys, I just picked up a new PCV valve and just wanted to pick your brains on a simple/stupid question. I (like most of us I would imagine) can't get my hands in between the runners on the intake manifold to get a good grasp on the PCV valve to pull it out. Do you guys have any tricks you've developed for getting it out pretty painlessly? The grommet still looks pretty decent so I was planning on reusing that one so I didn't want to tear that up to get the valve out. Any thoughts or suggestions? Thanks in advance!

I use a pair of pliers to grab the hose at the top of the pcv and pull it out being carefull not to apply to much pressure to damage the hose.

You can wrap some tape around the gripping ends of the pliers to help avoid damaging the hose, just in case you don't know your own strength.

Hey Mike-

I am in Arlington. I have done this abunch and like you said it is a beotch especially when the grommet is old and hard. Use some long locking pliers and grab the PCV and work it out. If the grommet comes out too, not to worry, a new one is reasonably easy to put in. When the old one is out, make sure and put a thin coat of vaseline or white grease on the PCV before attempting to install. The PCV is a GM part, right. If not, take it back and get a GM.

Thanks for the quick replys guys! The PCV I picked up is the Autozone 1162 that I have seen referred to on here quite a bunch as a decent replacement. Never used one myself so not totally sure! If the grommet comes out am I better off just getting a new one instead of trying to get the old one back in? I'm not sure of the condition of the old one, but it looks decent. Thanks!

Yank the hose off and grab it with some needle nose. :biggrin:

Use an original GM/ACDelco PCV valve. I wouldn't take a chance with anything else.

Other than GM's AC Delco PCV....the AutoZone 1162 PVC Valve works fine!

I'm usually very sceptical about using anything "Non AC Delco" on these cars, however, I've been running one for a while with no issues. Alot of turbo buicks using these with good results. When I heard this valve was being used and recommended by people like Eric Marshall and Bob Bailey....I decided to give it a try. The AutoZone 1162 PCV Valve is one of a few which is metered correctly for our turbo buick cars.

Since you've already got it.....I'd go ahead and install it.....you may find some plus's with it.

However, since it is slightly shorter in overall length...depending on how your PCV lines are running......you may wish to install a slightly longer section of 3/8" tubing on your PCV system to allow it to fit properly so it doesn't push the PCV Valve out of alignment making it sit cockeyed / crooked in the grommett. Don't want to have any potential leaks at the sealing surface here. Guess it will depend on your specific installation....if the existing hoses have enough slack in them to make up the shortfall of the PCV valves shorter length.

When disconecting hoses and small fixtures like the PCV, give it a twist a few times if it is rotating it should pull out fairly easy when you start prying on it with your pliers.

I don't mean to hijack the thread but Autozone calls for PCV1126 and is identical to the PCV valve that is currently in my engine. The PCV1162 looks different...it is all plastic and has a very small orfice hole, so it would flow much less air compared to the PCV1126. It's obvious that the PCV1162 would lower BLM's since it is less of an 'air leak', but is it correct for our engines? It almost seems that it wouldn't evacuate enough air to be fully effective in pulling out crankcase vapors. Thoughts?

I've had success with:

1. Do this when the engine is warm, makes the grommet more pliable.
2. Remove the hose.
3. Place a few drops of 3 N 1 oil around the base of the PCV.
4. Needle nose vise grips, and pull out with slight wobble.

I just bought mine from Autozone and they recommended the PCV1126 and thought maybe the numbers got transposed (1126 vs 1162). I will hold off installing mine until some more recommendations come in.

Thanks for all of the feedback guys, I really appreciate it! I had wondered about the 1126 vs. 1162 thing myself. If you have an Autozone person look it up, it comes up 1126, but everyone on here said the 1162 is a good alternative to the AC part. I haven't had any time to mess with it so hopefully in the next day or so I can get this done. Thanks again for the replies!

Hey guys, just figured I'd give an update for anyone who was following this. I installed the 1162 pcv and it seems to be fine just running in the driveway. I'm going to take it for a spin in a few minutes. It was mentioned above that the existing/stock hose going to the pcv is too short with the 1162 which was exactly the case, about an inch too short or so. It just contacted the stem of the pcv, didn't even get around it at all. I put a new length of hose on there which also made me replace that particular hose which looked a bit on the old side anyways so that worked on two levels! Thanks again for all the replies, I always like to double check what I'm doing on the car with everyone on here and as always, you guys are always helpful! Thanks!
