Hey guys, a quick PCV question..

[groovemasterodi]

Trying to check my PCV valve today and I got the hose off but the valve itself doesn't seem to want to come out. What I could find on previous related posts, was that you just appear to pull it out, and Haynes is equally ambiguous on this matter. Tried twisting it out, and the whole thing just spins around. Ideas and/or tips would be appreciated. Hope everyones weekend is going well.

Of course after I make a rare post, I get the valve out.

From my understanding, a rattle is good, no rattle is not. I blew through it & shot some TB cleaner in there(from valve cover side, as i read). Grommet to the valve cover appears in surprisingly good shape.

The main purpose of this is to resolve some misfiring at idle(PO300) by the way.

I was hoping to see it clogged up and befouled with gunk, but it rattles and has good air flow. Hose is also in good shape. I believe this goes from valve cover>pcv valve> intake plenum? On the plenum(or what i think is the plenum) side of things it appears to be quite oily. Does the Nation reccomend I attack that side of things with some seafoam, or is it supposed to be that way.

Apologies if these are questions of an obvious nature, just trying to get more knowledgeable in the workings and repair of my beloved Camry.

Thanks and cheers.

Well, I got the new PCV valve on no sweat, the grommet (gourmet? ) was more worn than I thought upon closer inspection, and a new one was also installed.

Took it for a test-drive and the initial acceleration hiccups are still there unchanged. Wires look like they need replacing, so that may be in the cards for tomorrow, bank depending. BOSCH FOREVER, jk. May also do the valve cover gasket.


I seek the thoughts/input of the community on this issue.

I ripped my grommet apart when taking it out. Pain in the ass because it got inside and I had to fish it out. Anyway I replaced it with 89-92 grommet I believe which is bulkier but it will be easy to take out next time. No leaks, works like a charm.

Same thing happened to me, fished it out as well. Still don't know why the damn thing is hesitating

Update: Just got some NGK wire plugs, pulling spark plugs, cleaning etc.

I seek the words of the Camry Gods on this matter!

Have you cleaned the throttle body? How dirty is it looking past the butterfly valve?

[JohnGD]

Yeah, when exposed to heat for long periods, the rubber becomes hardened and brittle. So PCV valve and grommet should be periodically replaced. ~$8-10 (both aftermarket and OEM).

What plugs are you using? If you are going to buy new ones try NGK Iridium-IX. But no less than NGK G-Power.

[groovemasterodi]

I got the G-power plugs cause im going to need to pull the valve cover and replace the spark plug tube seals I think, but for now I just need to get to work in the morning. When I fix it all I will be getting the IX NGKs.

Back to ze garage.

Well got the new wires and plugs in and I'm pleased to report, no recurrence as yet of the idle issue. So with a good TB cleaning, PCV valve/grommet replacement, new NGK wires, new NGK plugs, she seems quite happy.

Thanks to all for the tips and feedback.

Good to hear!

BTW, love NGK ignition products.

Cheers John. I think those may have been the original plug wires on them, as on 2 of them the bottom half of the boot was fallen down ontop of the sparks, requiring tool invention to fish it out off the top of the plug, fun times. The NGK wires looked vastly beefier.

Have a good one.
