Thank you for posting that link.
Part one was very well delivered last night, ready for Wednesday!

Abdolutely true.

Best thing about it: It only will become BETTER!

Hope we all learn a whole lot with tonight’s class! I had an interesting misfire for me to deal with yesterday.


I did an RC TEST with a sync and an intake pulse because I had low contribution on cylinder 4 on a 4 cylinder engine.
I didn’t see anything that struck me as odd with the intake pulse so I decided to clamp the PCV and check the crank case. The compression loss directly correlated with a pressure spike in the crank case which repeated itself every time. Within 20 minutes, I was able to know with 100% confidence that the customer was needing a new engine. All of this using a $0.50 piezoelectric disc and a couple plumbing fittings. Not having a transducer is a blessing because it’s forcing me to learn this.

That's quite interesting. Blow by testing in the crank case I've found little conclusive unless it was a really gross fault though.
I take it you checked crank case pressure with the engine running. If so was it already spotable at idle and did it show up worse at higher rpm?

It was indeed running. The problem was a dead miss under all conditions, just didn’t feel quite as bad at higher RPMs. I did not check with a borescope but my theory was a hole in the piston.

I’ve also used the delta sensor on the cooling systems quite a bit and you can see when the water pump functioning with it.

Have you found any pump impeller problems with it?

Not yet! I believe it is possible, but I also think that there’s a real possibility of too much turbulence to really know for sure.
