Diagnosing valve plate problems

[Dan]

Used a Co2 Fire exstinguisher Horn and hose as a stethoscope to listen to the head before.Thought that a doctors stethoscope would look a bit strange if sombody walked in on me.Also good for listening for hard to find leaks on coils as when the leak lines up with the end it's very loud.

So, in your opinion, it is less embarrassing.. or perhaps more professional to be seen holding a fire-extinguisher cone to your ear than a stethoscope. You have made my day, smiling-wise. But I bet you found some leaks my doctor would have missed.

I prefer holding my ear to the head... hearing aids don't you know

One thing I have seen is to use an electronic stethoscope with some Bose noise canceling earphones. I have not tried it, but it seems like a good idea.

Myself, I will stick with using my trusty screwdriver and hands.

I place a screwdriver with the tip against the tubes or compressor and listen on the plastic end.
You must try this once.

Have used the Head temperature useing a surface probe on each cylinder and it works well. But 9 times out of 10 the good old screwdriver as it's always at hand. We have an Electronic stethoscope had the chance to use it once. With some adjustment to remove the back ground sounds a good tool to use.
