As I was changing the PCV valve yesterday, I decided to take pics during the process. I hadn't seen any on the forum, so thought I would. Hope someone finds them hopeful. I've posted them in order.

The first thing to do is to remove the PCV hose. I have the "pinch" type clips. The easiest way to remove them is to use standard pliers. Since you should replace the tube, also, you don't then don't need to worry about damaging the hose when removing it. It takes some force to get the tube off. Simply turn it side to side as you pull it off, taking care not to damage the tube. I used fuel line (thanks for the tip), for the tube, rather than pay the price for an an PCV tube.



Use a 10mm socket to remove the bolts from the top of the cover.



The cover will probably not come right off. I used a rubber mallet to tap the cover. You might have to tap it on the front of the cover to remove it.


Look at the sludge in that cover! I used a rag and a toothbrush, along with some degreaser to clean it up. I actually sprayed the cover with "Gunk" degreaser and washed it, taking care to complete dry it before reinstalling.



THIS is the location of the PCV valve. There was a lot of grease in there. Make sure to clean it up.


You can very faintly see the gasket that sits around the lip of the base that the cover sits on. Mine was fine. Be sure to inspect yours before putting the cover back on. It may or may not need replacing.


This is after I had cleaned up the cover.


You then need to take a 16mm deep socket to remove it. Is was extremely hard to remove, and took a lot of force. BE CAREFUL, though, because you could possible strip it.


This is the location of the PCV valve after it was removed.


Installation is the reverse.

You coulda eaten off the EGR valve cover. Keep it away from paint and any live animals you wish to keep.

I had NO idea that something like that could get so dirty. I'm now rather embarrassed that I posted them. I didn't even know what the function was of the PCV valve until recently from here. The funny thing is, my car runs worse now than it did before I changed it. I bought some Seafoam, but need to have the figure "8" gasket replaced on my oil cooler line, and just changed the oil, so I hate to spend another $12 on a filter. (also just figured out with some help on where the brake booster vacuum line is. I may post pics when I do that, too..

Thanks for the kudos. While it was being changed, I thought it would be a good idea to take pics for those who (like me) have never changed one before.

The two hardest parts of the entire job were getting the PCV valve itself out, and getting the clamps back on the new hose, especially the clamps!

I loved the comments, tho, about how bad it was! LOL!

man oh man...pull a valve cover and take a picture of that for us! Good work taking pictures and showing people how to do this...I'm suprised no one has done it before with all the questions that are asked.

If I hadn't had someone else do that work last week, I would have...
I hope it is useful.

Theres actyally an OLD OLD thread with pics that showed the PCV valve change proceedure, I know cause I used it when i was a newbie...but this is good because now its an updated one....

One suggestion though, if you are going to turn this into a DIY, try to edit it to include step by step sentences to go with each pic and also include a "tools needed" list (like 10mm sockt, 16mm deep socket, etc.)

That's a good idea, and I thought about that, but didn't know how to include the information when I uploaded the pics from Photobucket. I JUST learned how to upload pics within a post the other day. As I was typing this I figured out how to do it.. I might re-do it, if I can remember what the first socket was that I used to get the cover off. I think it was an 11mm

If you put a new one in and it got worser what does that mean? what is the funtion of the PCV?

I think it means he either got a defective valve, or his hose that connects the the H cover to the intake may be collapsed or clogged....a new PCV vavle should either make it run better or little to no change at all....

The function of the PCV (Positive Crankcase Ventilation) is to draw crankcase gases into the combustion chamber with vacuum via the intake manifold...
