Search for the Crank Comprssion Test Video its here somewhere
If when the starter engauges and the engine rolls Over the "Sound is Even" thru the Crank ALL CYLINDERS (Not a dead Cylinder) = One Point GOOD Compression
If it don't have any BLOW BY at the Oil Filler Cap when Running = ANother Point Good Compression
With Me?? You Can check those easy^^^^^
Got a Extra Key I would go Check into tomorrow while they Closed if truck Outside
got the compression results back. number seven has zero compression. like zero. none. like almost a vacuum. what on earth could be my issue now? valves stuck open?
i would do a quick bubble test??? Did you say the #7 injector has already been replaced? I'd want to know that injector was seated properly. But a 0 compression. If this is true,, there's a fairly big hole in that piston. Hopefully the gp adapter was screwed in all the way. I'm sure it's completely possible,, but I've never seen 0 on compression. I've seen under 100,, but zero,,, that sux.
