Q: what could make my car have a knocking noise?

asked by on October 11, 2016

My car has a really bad knocking noise in motor. It will still crank and run just has a really bad knock. I've already took valve covers off to check if it was a rocker arm and it wasn't so what could be my problem? I'm hoping it isn't a slung rod but I've been told it wouldn't crank and run if it was a slung rod. So any information would be greatly appreciated.

My car has 180000 miles.
My car has a manual transmission.
