99 Park Ave Motor Knocking...Why?

It has always run great even though it have 195,000 miles on it...I drove it earler today and it was fine, but when I just go to the store and started it up, the motor is now knocking. I thought since it is cold out it would run away once it warmed up but it has not. Is the motor shot?

You may have spun a chronicle / main bearing. If so the engine is shot. Can be rebuild, but it is expensive. Try sourcing a used unit if on a budget.

Could be a slipped timing chain / belt. If so alot cheaper than replacing / rebuilding an engine.

Not as adjectives today, but a build-up of carbon in the combustion chamber can cause problems next to ignition of the fuel air mix and that sounds like knock.
