Mass Airflow Sensors.

[SilverFox]

I recently junked a car and took a few PM bearing components.

These include O2 Sensor, Mass Airflow, spark plugs, Cat - California Equipped.

The mass airflow was by far the best next to the CAT, the MAFS, had platinum wires and pads, plus it has a ceramic circuit board with silver(Color) traces.

Heres some pics from the removed board, the whole deal was in this nasty jelly substance..

Hi Silverfox,

Did you weigh the the precious metals?
Just wondering whether it's worth approaching the breakers yard for a few!

The sensor in total weights at 4.1 grams w/ wires.

I haven't done any reduction of refining since mid october since I can't do indoors.

current price makes this roughly 27 bux a gram, but the stannous test was only PT positive, its not saying that its pure pt. Keep that in mind.

Ok, thanks for that.
Think i'll go grab a few and see what i get out of them.
Might be able to get some cheap cats while i'm at it!

More PT Positive automotive scrap.

This is the float sensor for fuel tanks circuit board in early 90's model GM vehicles.

So Buzz, How'd you make out ?
I also had an assay completed, I used 4 mafs into 1 lot.

My results show, its not worth refining / not worth dismantling....


I'd like to hear your results.

 

[Buzz]

I tend to agree.

I could only get two but after breaking them down I can see that i would be hard pushed to make it worth the effort.

Ive been getting these parts free, I know mechanic he gives me any extra parts he has laying around.

sorry to hear they contain so little.

 

[Buzz]

I guess if you get them for free and time is your own, then it could be worthwhile.

It's amazing how fast scrap adds up over the weeks.
