I picked up the valve today and will install shortly. Looks like will need a 19mm wrench or socket to fit in that tight space.

The part number is 12204-31050 and paid $9.87 with tax.

 

Part Numbers:

12204-31040 - 2006 to early 2007 IS250 6MT (09/2005 - 01/2007 Production), 2006 to early 2009 IS250 6AT (08/2005 - 01/2009 Production)
12204-31090 - late 2007 to 2012 IS250 6MT (01/2007 - 08/2012 Production)
12204-31130 - late 2009 to 2013 IS250 6AT (01/2009 - 04/2013 Production)
12204-31050 - 2006 to 2013 IS350

Installation instructions:

1. Apply adhesive to 2 or 3 threads. (Toyota Genuine Adhesive 1324, Three Bond 1324 or Equivalent)

Thanks Jeff for the info. Before reading your reply I was going to use the anti sieze I used for my spark plugs. I wonder why they would want an adhesive. Here is some info I found on the adhesive:

 

I replaced my PCV at 90k miles. From what I recall, Loctite Blue is equivalent to the Toyota 1324 thread adhesive. Just put a small dot on the first 2-3 threads on the valve, and you should be good to go.

Edit: Nevermind! Just saw your cross-reference info. I gotta learn to read the whole post before replying...

 

Good info, thanks guys!

 

Is this a rule of thumb? 90k? I'm at 83k...

Also, can someone explain how this system works? I assume there's a line running from the crankcase that feeds back into the fuel lines?

 

For how cheap the part is it would not hurt to change it.

 

i had my mech replace it when he did the plugs at 60K miles. I don't plan to replace it again until 160,000 miles.

 

I replaced mine, and it was cake. I shook the old one, and it still rattled around...so I know it was still a good, functional unit. But for $10, it was a preventative maintanence thing.

 

Should anything be known before replacing? Should I let me car cool down for a bit or anything like that? Is it as easy as just disconnecting the hose and swapping out the valve?

 

^Easiest when cold, in order not to burn yourself. It really is that easy. LOL!

 

What did you use for the adhesive? I haven't replaced mine yet because I'm not sure which to use other than the Toyota brand. Any link for which one can find in my local auto parts store?

 

I only used anti-seize actually.

 

Per the table you posted back on May 9th, this would be the equivalent, or am I misunderstanding your question? That table you posted tells you exactly what you need. My link is for loctite 271 which is the equiv of that Toyota 1324.

EDIT: That is an incredibly tight space. My 19mm, long socket wouldnt fit because the intake manifold is in the way, and a shorter length socket doesn't allow enough room for the valve to fit in to remove it. Then, how would one torque it down even with the socket issue? Ideas?

 

Hi guys,
I am trying to replace the PCV valve on my 07 IS 350, and I can't get the darn thing off. I tried using a 19mm open end wrench. Any ideas on removing it?

Thanks,

Peter
