LOUD knocking sound from engine?
i have a 1993 mercury grand marquis LS and recently the engine has been starting to clink and ping along with rpm's it wasnt bad at first, but now its non stop. even when idling its constantly making a metal on metal contact sound. whats wrong? should i just junk the car and move on?
Sounds like a rod knock or some other catastrophic engine failure. I would strip the car of all parts you could sell on Ebay and junk it, as the value of that car with a blown motor is pretty much nothing. Good luck.
