When to worry about engine noises?

Yup I get what you're saying. All good here. They can also run "ok" on 7 cylinders with an exhaust rocker laying in the head. lol. To add some humor to the thread, I once pulled the car into the trailer with only 4 plug wires on it. I thought, man that ran like crap, and started hard. But it ran NOWHERE near as bad as you would think with literally zero fire in 4 holes. Was just the Dummy driver that forgot to put the plug wires back on the plugs after reading.

The previous 360 in my Duster ran pretty good on 7 cylinders with a cracked cylinder, broken ring land and seized piston pin. Spewed coolant steam out the exhaust and the oil was vanilla milkshake but it still pulled hard when I goosed the throttle lmao.
