Replacing PCV valve on '93 X

[KarmicFlea]

Hey all,

I'm in the process of replacing my X's PCV valve and could use some help confirming its connected properly. The replacement part I got is manufactured by/for Champion from Autozone. It is a valve with a double 90 plastic hose connector connected to the top. The PCV I have in there now has no plastic double 90 hose connector on it, and is connected metal to hose only.

I was just going to pull the double 90 connector off the top of the PCV valve and plug it directly into the hose. Can anyone confirm that that is the proper way to install it, or do I need to fix something that someone else screwed up and get it installed properly?

Thanks in advance.

It's correct the way it is. They didn't come with two ends off the one side. It's just a standard PCV.

Before you pull anything, clean up the area around the PCV valve. The dirt and debris on the valve cover and around the rubber grommet can get into the engine.

Yank the hose off the intake, then pull out the old PCV valve with the 90 degree rubber hose attached.

Check that the new PCV valve is indeed the same size as the old one, and the factory rubber hose will fit on top. If not, take it back and get a new PCV valve somewhere else.

They probably include the double 90 connector to take the place of the rubber hose and the fitting that's in the valve cover, but I'd rather keep the factory fitting and use a rubber hose than a whole PCV assembly.

If the PCV valve fits in the rubber hose, make sure theres enough life left in the original rubber hose that it will seal. You should also check the valve cover grommet to be sure it's soft rubber and isn't stuff or getting cracked.

If everything looks good, sure, just pop on the new valve and use the old grommet and hose. Usually it's best to replace if you can, though, especially if they're original and getting up there in age.

You'll also want to plug that open vacuum line fitting in the pic. Grab a box of the rubber vacuum caps from the HELP! section of the parts store, or get the multi-pack if you're not sure what size will fit.

Thanks for the tips. I will follow the steps you've outlined.

Those open vacuum lines are there because I had to pull them to get a clean pic of the PCV assembly. I reconnected them after I had the picture. Good spot though.
