[skunked]

Good friend of mine (he's like a second father to me) took his Jeep to the local quick service for an oil change as he normally does every 3K miles. He noticed the oil change was taking longer than usual when the manager approached him and asked him to step into the garage. When they went out into the garage the manager started the jeep and and it made a loud knocking/slapping noise and the engine was shaking violently. At this point they were unsure what it was and offered to look further into it and offered him a ride home, which he accepted.

Hour or two later they call and say the oil was milky (provided a sample in a jar) and thought it must have a blown head gasket. He called AAA and had it towed to his local mechanic that has done some work on this jeep in the past. The results just came in, he has zero compression on cylinder 2 and another cylinder is really low. The mechanic noted that there is no sign of "milky" oil and he believes the #2 piston has a hole or the rings are completed gone.

It has the 4.7L V8, 220K miles on it. Normally I wouldn't think much of this but I feel as if the engine letting go at a shop during an oil change is an odd coincidence. Was the engine fired dry and are they trying to cover it up?

He is very meticulous, his last jeep went 360K miles on the stock engine and auto transmission, still drove fine when he donated it.
