Well good news today. I started my night with a compression test on the jeep. Let's just say somehow I managed to make the most simplest first thing you learn in middle school auto shop the most difficult task. I followed the manual exactly on how to compression test my motor. I hooked up the hose and gauge, crank the motor, not a damn thing the gauge bounces but nothing so I try all cylinders still nothing. What!! How can this thing run without compression and run good too.
Call up my buddy "that's weird" he says "try hooking it up to your lawn mower." I think good idea..... Damn good compression on mower and its holding pressure.
He says "I'm coming over something is not right"...... sure enough we get the same reading as before but it worked on the lawn mower why not my jeep.
Me "Oh wait I used a different hose on the mower".
My buddy "Maybe the valve core is bad on the hose"
Me "Duh! Why didn't I think of that"
We replace the core... 145-150 psi on all cylinders, boy I felt dumb. Then we did a cylinder leak test and they all held exceptionally well. I felt pretty good considering I rebuilt the head myself in my garage 3 years ago with just my basic knowledge of how to do it.
Now I know my motor is in good shape so I will order that new dampener and get my timing problem figured out.
