You, sir, do some seriously impressive and thorough work. My hat's off to you! I wish there were more mechanics like you, willing to go the extra step for a customer.
Did you save all the gunk you got out of the engine in a bucket, so you could show the customer exactly what it was that he was facing, and what will happen if he doesn't keep up better on maintenance?
