Yeah, I’ve talked to a few mechanically inclined people and they said the same, short of tearing it apart there is nothing I can do. One told me to look for exhaust with a blue color since it would indicate metal parts being worn down. saying it was the oil change place to begin with would have been tough since it was a month and more than a 1000 miles later that I had this happen (could be sabotage I suppose). Further more another mechanic said that slick 50 would help extend the lifespan in this situation. Any truth to this?
Thanks once again.
