Hello all I need a sanity check. My 05 GX470 was running great. However the starter was intermittently going bad. Last week the starter finally went.. Had it towed to my local mechanic. My wife picked it up it started really rough and then she tried to drive it. All the warning lights came on and it was bucking and hesitating. She turned it around and brought it right back. She didn't make it one block away. Told the mechanic what happened and told them to figure out what they screwed up. Today the mechanic said there is no compression in cylinder 8. When you replace the starter you have to remove the intake manifold to get to it. It is my understanding that no compression could be a bad valve or bad cylinder. Clearly they did something wrong when replacing the starter. Could it be debris from the swap falling into the block or something? An engine does not go from running great to zero compression in cylinder 8 overnight for no reason right?.
