Yes, it seems that for some this task is daunting. So, here it is ... the official tech writeup on (insert dramatic theme music here) How to Change Your 3.4L (3rd Gen) PCV Valve!


Ok for starters, we need to make sure you have everything you need. This list will help you with that:
- New PCV Valve. Buy OEM, or not, it's your call.
- Beer. This is critical to the post-install ritual.
- Napkin or towel of some kind (perhaps one of those moist towlettes they give you when eating BBQ ribs would work too)


Alright! So you have everything you need... NOW we get to the good stuff.

First, you want to greet your motor with a hearty handshake and a hello. It will greet you back:


Now that formalities are out of the way, let's get down to it, shall we? Let's find the PCV valve:


Yay! You found it! Ok, first thing we gotta do is loosen the little clamp on top, that holds the vacuum tube onto it:


Now, pull the valve out of the cover. You can pull the vacuum line off first if you want, or wait til the next step. The world will not end either way...


If the line is still attached, take it off so that you can take the old valve out into a field somewhere and set it free.


At this point, I find it extremely helpful to take a break. You've clearly done enough work by now to make a drill instructor blush with envy, so why not reward yourself? Time to have a few big o'l swigs of that frosty cool beer you've been holding next to you this whole time...

Back to work! Let's get this sucker back together again. First thing we gotta do, is put the vacuum line on the new valve. I took the liberty of assuming you didn't need a picture for this task (plus my camera was acting up). Don't forget to put that little clamp back in place!

Ok, so the line's reattached. Bet you can guess what comes next. Yep, you did in fact guess it! Put that PCV valve back in. Just push it in there.


And ... we're done!

Yes, really. Now, what you should do is use the napkin or moist towlette you were instructed to keep handy, and wipe the 17 dust particles off of your hand. If you actually needed this guide to change your PCV valve, we can naturally assume that you have an aversion to greasy hands, so this will help you maintain pristine cuticles and that just-showered feel.

Ok, now go finish your beer. You've earned it!

 

A well documented write up. Is there a recommended brand of beverage?

 

I don't get it. Can you be more specific?

 

now thats a write-up

 

Now the funny thing is, try that for the 3.0. You'll need a case of beer first, then realize, drunk of course, that it's a pain in the ass.

 

What's that you have for your ISR mod?

 

yeah, your isr looked cool/funny... and my hat goes of to you my friend for giving us such and insightful writeup... I feel as though I have gained soo much knowledge that I shall skip my 8 am English class... thanks man, you rule...

oh and(flame suit on) what part of the PCV valve wears out so that you need to replace it. I just dont see why it needs to be replaced, can someone explain... thanks

 

now i would like you to document a complete teardown and rebuild of the 3.4 engine,step by step! by the way that thread was tediously accurate....nice! im out

 

Hands down the worst write up ever! We need more detailed pics! Haha j/k. Thanks for the great writeup. It'll do idiots like me good.

 

Well, since they sponsor me, I personally recommend Breckenridge Brewery beer. (Makers of 'Avalanche' and 'Hefe Proper', among other very fine brews.)

Well, I wondered how many posts until someone noticed that. haha That's actually the top to a can of aerosol brake cleaner. Turned backwards, it fits tighter than the PVC cap I bought! Though I've recently read 96_Runner's re-writeup on the new and improved way of ISR-ism's, so I am going to get some new parts and redo it. Or I may just fab a new piece out of fiberglass so I don't have those stock intake-udders hanging out. Definitely a fan of the clean look.

 

The air flow goes from the head to the throttle body, so it can get pretty gunked up with oil and such.


(nice write-up DBG!)

 

wow its really that simple. I wouldn't have belived it if I didnt see it with my own eyes. Awsome write up!!!!!Gonna head over to the dealer, to pick up the valve, then over to Henery Louis for the ribs, and then to Safeway to buy beer. I was wondering if I gotta buy beer that comes in a can or in a bottle??? Thanks for a acomadating a non-beliver.

 

First of all, great write-up. However, I would like to point out that you can save yourself some money by pulling the PCV valve and spraying into either end with carb cleaner. If it freely "clicks" upon shaking, the valve is fine.

(not trying to detract from your write-up)

 

Good point 96, that's actually all I do to mine. But, I wanted to keep this in the realm of "easy" and "non-dirty"...

 

Cool! Now get the aerosal cap outta there!

(When I first did my ISR mod on my 98 Taco, I used a Gatorade cap, beat that!)

 

well - what a great writeup


oh and I hattttttttttteeeeeeeeeeeeeeeeeeeeee grease!!!! YUK!

 

Wow, where did this thread come from.
Great writeup.
