PCV valve - when to change

Hi

When do you change your PCV valve? In other words, after how many miles?

I have a gen 5, 2002.

Thanks

Toyota never mention anything about it.

I would personally do it at 30k. It is cheap to change and easy DIY

Its not hard to tell when the PCV valve needs changing. Pull it out its hole, and shake it. If it clicks, its ok. If not, its crudded up, change it.

so the PCV valve just pulls right out - pull straight upwards? is this right?
Of course, the end that attached to the hose I need to release the retainer clamp.

Be very careful when pulling it out - if the rubber grommet that holds it in is hard and brittle, you won't be able to put it back in without completely removing the old grommet and installing a new one.

It can be very tricky to get an old, brittle one out of the valve cover.

Replaced PCV valve today <<< go to post number 8 for the answer

Quote:
The PCV is located on the back valve cover it is on the passangers side and it is black whith a hose connected to it that goes to the intake manifold you only have to twist it a bit to get it out but you don't need any kind of tool. it costed me $ 3.99 at autozone. I think that it is worh the money if you are having a bad idle.

Anyone got any photo that shows where it is, I've searched the forum and google, but found nothing. Or maybe show me what the PCV valve looks like on Gen4 V6 camry. Thanks.

Also, do I need any tool to change it? Screwdriver, etc?

On a toyota that has been well maintained (meaning you have done proper oil changes) I wouldn't worry about replacing the PCV valve until 60k. I have done that on several of my Toyotas and even at 60k, the valve is working fine I just replace it then because I want to.

Exclamation

I've put over 500K combined miles on a Mazda and three Toyotas and have never seen a PCV valve go bad.

You have never seen one doesn't mean they don't exist.
It can go bad for many reasons.
When it's clogged, you won't feel it but you'll start getting oil leak, or get bad gas mileage.
