Good information Bart, I have priced the bungs and you are right they are expensive. Thanks
Make Your Own A/F Sensor Bung
2
This has been used for years as an alternative to purchasing the Expensive Stainless Steel Bungs.
USE a Spark Plug Non-Fouler 18mm (item available at most auto parts stores
OK, you're asking WHAT's THAT :rofl3:
It's a little plug that is into the sparkplug hole. It has a small hole in the bottom which allow the Gas Vapors to enter into it, but keeps the oil out. When the spark plug fires, the gas vapor is ignited and the engine works.
The major purpose is preventing oil from splashing onto the plug and FOULING it out.
Heres a picture of the package, You get 2, yes that's right 2 for about $5

Make your cut with the hacksaw above the thread portion & as close to the next section of the Non-Fouler that you can. Use a file to smooth the bottom, since it will protrude into the exhaust.
Now you've got to do a little bit of work to use it.
Simply take the hack saw and cut the Threaded portion off & discard.
Next you will need to drill out the bottom of the remainder, where the Small hole is/was. Place the Non-Fouler in a vise and use a 1/2" drill to make the opening larger. The reason for doing this, is when you screw the A/F sensor into the NEW BUNG, the tip of the sensor must go through the bottom.
Now you already know the rest of the procedure, drill hole in exhaust tubing or header, weld the NEW BUNG in place. You're now good to go.:ride:
