Okay,Just got my compression tester. I've never done a test before but I followed a couple write-ups I found online. Here's what i got.
I ran the Jeep for at least 20 mins until it was hot.I then pulled all the plugs and pulled the asd and fuel pump relays. Hooked up the gauge and got these for readings. I did 5 cranks each time. I did two tests on each cylinder.
Cyl 1) 170/170
Cyl 2)150/150
Cyl 3)180/180
Cyl 4)180/180
Cyl 5)180/180
Cyl 6)180/180
I then stopped for about 15minutes to talk with my neighbor about the noise. I went back to the Jeep and redid the test on cyl 2 since it was the lowest. Engine was still warm though. I got 180 both times. I didn't bother doing a wet test since they were all within range.
Listened with the stethoscope for the 20th time while my wife was keeping it at 1500rpm where the knock is most pronounced.It's definitely loud listening through the oil pan however I still think the actual knock noise is loudest when I put it on the bellhousing at the flexplate.
What's next???? :dunno:
