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

Also kills wasps on contact!

 

Very nice pics, good job!

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!

 

Nice effort! You should post a link to this thread in the "giving back to the community....DIY's" thread that is stickied at the top of the main g1 forum page so that it doesn't get lost.

 

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.

Done!

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

 

I just edited my post and added descriptions. Please let me know if I need to add anything more.

Thanks all!

 

1 minor issue is that I believe it is a 10mm socket to remove the cover bolts.

See?? I knew I should have left alone.. I wasn't sure.. shouldn't have guessed. I'll change it (again!).. Thanks!

 

The funny thing is, my car runs worse now than it did before I changed it.

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...

 

WOW that looks awsome, I will do this in the summer time, except I will get an honda PCV Valve and a proper hose, labout on me I suppose :bash:

THANKS MAN!

 

Nice pics, they are actually focused too!

The first time I changed mine, I had quite a bit of sludge too, so I'm glad you posted this to show me how much worse it could have been.

 

With that sludge, you should do an auto-rx on that engine.

 

If it werent for this forum, i would have never found the pcv cause the chilton said it was lacated in a totally different spot and i thought i was begining to become blind! Question, how do you know if your PCV is going bad? my car is sputtering when coasting.

Probably should have started a new thread...
Anyway PCV - Positive Crankcase Ventilation. Basically the crankcase emissions have to go somewhere so instead of letting them into the atmosphere they go back into the intake manifold.
I don't see how the car would tun worse by replacing the valve, perhaps the symptoms could be described. It could be a conincidence that something else went bad when you changed the PCV valve. The hose which connects the top of the valve cover to the intake manifold could also have a hole in it or be blocked. It should be replaced at the same time you replace the PCV valve.

By the way I do believe worser is not a word

 

right on time!! im bout to do mine! thanx alot man!

 

Car is making a bogging noise when coasting...

Just rescently my car is starting to make a boggind noise al most a sputter in the noise of the exhaust. what could be the problem? only thing i have not replaced during tune-up is PCV. What are the affects of a bad PCV valve?

Oil consumption tends to be high also.

 

Just disconnect the hose from the manifold. With your thumb over the end of the opening block it, open it up, partially block it and you will be able to replicate the problems a broken or stuck/blocked PCV valve would cause.

 

If you block the PVC valve you should notice the idle change slightly. Most likely it will drop in speed a bit.

 

Your car should completely die if you remove hte hose from the PCV valve/valve cover.
