I have had the 1416 code for over a year now, and will replace the checkvalve. I have seen the intake removal post, but was not sure if I need a replacement gasket for intake. How does the intake seal on a 2002 Z06, is it an o-ring? Any other tricks for replacing the AIR check valve behind the block? Thank you, G
I replaced mine last year at about 30k miles. Although the intake o-ring seals still looked good, I opted to just replace them at the same time.
A couple of tips I learned were to lengthen the vacuum hose "straw" connection at the rear of the manifold, and to use alligator clips to hold up the two rear manifold bolts, when you slide the manifold out and back in place. The braided fuel line can stay connected, but I found it easier to disconnect it to get the fuel rail out of the way.
I agree with quick silver. I just remove the fuel rail/injectors as an assy and just FLOP them over on the fender still connected. I use close pins to hold the rear bolts up to keep the bolts from interfeering with manifold removal.
Gaskets "O" rings can be found at Advance Auto made by Felpro for 27 bucks.
Make sure that you clean all the dirt and sand from under the manifold.
Seal the knock sensor rubber plugs with RTV to help keep water out
Yep, purchase a nylon line repair kit and lengthen that dam short little vacuum line.
DON'T REMOVE the bolt that fastens the A.I.R. tube mounting bracket to the left side head. The bracket is slotted, and you only need to LOOSEN that bolt to slip the bracket off.
If that bolt is removed, it will be a major PITA to get it back in.

All good tips. Let me add one more: Use anti-seize compound on the threads of the new check valve. If you ever have to go back in for any reason, you'll be very glad you did. Same for the two small bolts where the tube bolts to the exhaust manifold, if you remove the whole tube assembly. Btw, there's a small gasket used at the exhaust manifold end of the pipe, as you can probably tell. It's reusable if you don't damage it.
Make two 1" long pieces of rubber tubing with approximately 1/4" ID. Slit the tubes all the way up the side so that it is open. When removing the intake the rear bolts won't clear the cowl, but will conveniently drop down when you lift the intake to pull it forward/backwards during removal and installation. Use one tube on each of the two rear bolts to hold them up out of the way while you pull the manifold out and put it back in. It's easier than having someone hold them up while you get everything removed and reconnected.
Once less aggrevation while jockeying it into place while ensuring that all of your connections are in place and wires are out of the way!
