Anything’s Possible
There’s no telling what the OP was hoping for when he messaged Steve, the mechanic. He told him that his car makes weird noises, even after replacing the valve seals and whatnot. The OP wanted Steve’s expert opinion on the matter without even taking said car to Steve’s garage.
Steve offered the most reasonable answer to the most unreasonable request. “Anything is possible.” You couldn’t seriously hope that Steve could diagnose your car’s problem without even laying eyes on it first, can you? If you ask us, and we’re pretty sure no one is, the problem is with the flux capacitor. Either that or they have to replace the exhaust drive.
