Guess What I'm doing this weekend?

Cracked injector bodies don't generally lead to piston failures, but they can lead to too much fuel in the oil which will damage bearings and the like. 

Injector nozzle and stuck injectors are what lead to piston issue. 

 

 

As for the compression test it should be 350 psi minimum and within 20% cylinder to cylinder, from the FSM

That being said weak batteries, weak starter, or a cold engine can effect the reading. Valve adjustment can also effect the readings. 

They are all very close so I would assume batteries are weak or the tester is off, or the starter wasn't ran long enough. 

 

 

On the most important note...do NOT run that AFE fuel filter. They are not fuel water separators and only 7um absolute, not the 3um they advertise. 

The best filter to run in the OEM housing is the Baldwin PF7977.
