My '99 doesn't have a "PCV Elbow" on the back of the intake... It has a long plastic tube that makes a gentle arc behind the intake and then comes straight at the manifold. No elbow, just a normal straight hose connecting it to the plenum. I'll see if I can get a picture. It may be worth finding if you can eliminate the elbow and never have to worry about it again.

The PCV valve on the 4.2L is a liittle further back in the valve cover passenger side. Just follow that line and it will lead you right to it
I show two types - One w/2 90 degree bends and the other is vertical w/the 90 degree bend being on the boot to pipe connect.
Doesn't list a heated one , but I've seen them before where there fastened by a metal retaining clip - goofy looking deals.

So glad I found this forum.. I chased this code for months and finally pinned it to the PVC elbow. A 8$ part almost broke my bank. Glad I came here. Saved me a ton of time. I'm still not sure how I missed that elbow when I did the starter fluid test for leaks. But all is well (just waiting in this stupid DMV line now)
