Car Fix DIY Videos

In this episode, I’ll show you how to tear down, inspect, and repair your Porsche 911 CIS Airbox. I’ll show you how to take everything off your airbox to get down to the part itself, show you where the airbox fails, how to repair the cracks better than the factory, and install a pop-off valve to prevent it from happening again in the future.

The factory airbox relies on the threads of machine screws in plastic, which strip out causing air leaks which can lead to poor running CIS systems. I will be replacing these fasteners with nuts and bolts with washers to provide compression to the two airbox halves, and be sealing up the crack with an adhesive suitable to ABS. I’ll also show you how to install the pop off valve using a hole saw, dremel tool, and some JB Weld PlasticWeld epoxy.

Shoot me any questions if you have them.

About: Join me as I stumble along rebuilding the drivetrain of my 77 Porsche 911S. To be honest, I have no idea what I’m doing. I’ve never owned an aircooled car before this one, there’s a huge learning curve, and I’ve been avoiding this since I bought the car years ago. I can’t afford to pay 911 prices on things, so I’ll be doing as much of the work myself as possible.

Thanks for watching and please share any thoughts or comments you have!
