Is there a DIY for replacing the PCV Valve?

I plan on changing the PCV Valve this weekend and I'm sure it is not that difficult but is there a DIY with or without pictures for replacing the PCV Valve? Thanks.

wow that has to be by far the easiest thing to replace. there is a small tube that runs to ur driverside valve cover and its right on top, pull it out while the engine is running and see if its got suction, better yet take it out while the engine is off and shake it, if it rattles its good.
peace

Here some info regarding our (PCV = Positive Crankcase Ventilation). -Mike

Location:
Its a little plastic valve in the driver side valve cover, with a hose attached to it.

What It Does:
The PCV valve is designed to compensate the engine ventilation needs at varying engine speeds. It is operated by manifold vacuum which increases or decreases as engine speeds change.

Maintenance:
A PCV valve should never be cleaned and placed back into service. Cleaning a PCV valve will result in a clean PCV valve, not a new PCV valve. There are contaminants that will remain in the PCV valve that can never be flushed out. Additionally, there is an amount of wear that will be experienced by the spring that cleaning cannot replace. The recommended replacement intervals are a maximum of 12 months or 10k miles (16000 km). Since vehicles and operating conditions vary, the valve may have to be serviced more frequently. If it is suspected that the valve is sticking or if there is evidence of sludge, the valve should be replaced. All hoses or tubes used in the PCV system should be cleaned and inspected. If any cracks or breaks are noticed in the hose, it should also be replaced. All hose connections should be inspected to assure an air-tight seal. -Mike

loosening the clip (or whatever it is around the PVC) is easy, but what is the proper way to tighten and not damage it? I know bodyshops have special pliers for that but I don't.
Thanks

Yes! Great question.

Does anyone know what is the proper way to tighten clamp/clip and not damage it?

And do you need any special tools to tighten or loosen the clamp/clip?

No spec tools needed for that. See ma pic above. You see the clamp? It's very simple to press down the clamp. Really easy, believe me. -Mike

Yep, you got it. In the course of time it could be, that the hose is kinda too tight. Then please try to remove the hose by turning the PCV. Turn -> Pull, Turn -> Pull. -Mike

Do I remove the other end of the hose (opposite of the PCV valve) and than than the engine suck it up?
Or do I take out the PCV valve and pour it right in? Thanks for the help.

I tried to replace the PCV Valve today but I had difficulty and I need you guys to help me please.

Pulling the PCV Valve out the the engine block was easy but...

when I loosened the clip/clamp completely I was not able to remove the PCV Valve. I tried to turn and pull many times but I was not successful. It felt like I was going to break/tear the hose if I kept going at it. It felt like it was stuck in there very tight and it was glue in.

IS THERE ANYTHING ANYONE ELSE CAN RECOMMEND???

The PCV Valve looked very dirty and I wipe it clean with a paper towel before I put it back in because I was not able to remove it.

PLS HELP!!! I want to change it ASAP! THANK YOU to everybody for helping me!
