Well guys, the leak down test doesn’t lie! Looks like pretty good compression on most of the cylinders, but cylinder 5 is DEAD. TDC shows about 10psi at 100psi pressure and heavy air leak through the exhaust. Looks like we got a burned exhaust valve! Time to break out the pocketbook.
Well at least you know what you are dealing with. You also have some extra spare parts for the future (injectors lol). This must have been an auction vehicle? The way you got the original injector out was the clue that someone was in there trying to solve it, couldn't and buttoned it back up and off to the auction block.
Keep us updated and good luck.
