So I had a recall done at the dealer and they told me I need a new pcv valve. I got one from a local store v513 but noticed another part number of 6p1282. Are these interchangeable? I installed the v513 but just want to make sure it won't cause any damage and it is the right one. Im not sure i notice a difference after installing. Thanks

 

This is OEM Toyota part #1220431050 for 06-14 IS350 and 06-09 IS250 part # 12204-31040
The 10-13 part #12204-31030 for the IS250 There are different ones but not sure the exact differences....

 

Sorry I was referring to non-oem parts. But thanks for the part numbers. I guess for peace of mind I will pick one up. Would the PCV valve have anything to do with a high idle?

 

yep it definitely could

 

Sorry for the stupid question, what is pcv supposed to help? Or how often we have replace them? Thanks

 

PCV is to vent the crankcase, I would imagine more for when you park than anything. It is to used to lower pressure. My BMW uses a relatively expensive system that requires changing about once every 100k or so. I would be surprised if a lexus uses a std vent system

 

Thanks. Seems the problem has cleared a little. It's a pain to get at but for the cost I will try oem.

 

It's just a simple little PCV valve that needs to be changed. Don't need to replace anything else unless your hose is cracking.

Yeah, it's a pain to take out if you don't remove the intake manifold. An open ended wrench will help out though. You'll need to put some adhesive on 2-3 of the threads, Loctite 271 (red stuff) is what you want, or any Toyota 1324 equivalent, as I don't recall them putting any on from the factory.
