Hey Gang - after scouring this forum for help w/ the dreaded p0410 (thanks -btw), I've got parts, air box removed and still cannot seem to get the check valve to budge. Yep - after 150k miles, its rusted, and I've hit it with PB catalyst a few times, and still - nada. I've heard mentions of folks cutting the top off to use a socket - but can't quite figure how to do that w/o creating a huge mess.

I'm open to suggestions. Thanks in advance.

got it - ended up getting underneath & removed the pipe at the manifold, then a hacksaw to the valve to be able to get a socket over top. Wow. Who knew?

So far, no codes. Fingers crossed!
