I'm a little worried about the pistons.
Short of tearing it down it might be possible to measure down an injector hole with a vernier caliper to check piston height at TDC.
I've done this in the past when owners have tried to submarine their vehicles.
Your looking for all the pistons to measure the same height.
Or if your guy's equipped a 'scope trace from an amp clamp on the starter cable would give comparative compressions.
And try to get a code read print out from the dealers.
