My clamp had the screw facing the firewall which was a reasonable thing for a 7mm ratchet.

I had "cleaned" the PTC nipple before with TB cleaner and a toothpick. This time, with the air hose off, I could see the dirt and used a screwdriver to make the hole square again.

I used WD40 to clean it, followed by TB cleaner to get the WD40 off. Works great.

For reassembly, I snugged up the Turbo end of the air pipe first. Then put all of the vacuum lines back on. Then clamped the pipe to the air box. Followed by tightening the turbo end clamp.

It works. The backs of my hands look like a war zone. I guess it is time to buy another bottle of hydrogen peroxide :>)
