"Knocking" can be a number of things bearings, wrist pins, etc... Prices vary depending on shops' labor rate and parts supplier. Shop around and I'm sure each shop is going to want to see/hear the problem. Who knows, it might not need a new engine.

Rods are knocking,

To put it in layman's terms it means tat the big end bearings are shot and it will be new bearings and crank shaft grind which leads to engine rebuild which leads to lots of dollars. I do not consider it a stupid question at all as it is a common statement by "shade tree mechanics" looking to make a fast buck at your expense.. It is best if you have a series of tests done to determine the condition of the engine first. Find yourself an accredited ,reputable mechanic and have the following tests done.1--- have a compression test (dry then wet) done to determine the condition of the rings and bores. IT will also find if there are cracks and head gasket problems( minimum psi should be around 120psi). 2--- have the oil pressure tested with a mechanical gauge to find the working oil pressure ( minimum idle pressure around 20psi) reduce the engine idle to as slow as possible and listen to any knocks in the motor. Pull the plug lead of each cylinder in turn and if the knock subsides it can be worn gudgeon (wrist pins) pins in the pistons. When you have the results from all these tests you will have a good guide as to rebuild, replace with a reconditioned engine or get a good unit from the wreckers.

You mean the engine block. Depending on the damage, it probably could be welded, but for a 14 yr old car, it may be cheaper to buy a used engine complete.

My 1999 mercury cougar engine is nocking

Check fault code and look for faulty engine knock sensor if you have one. If it is a conventional unit ,it may be time to check big and main bearings.

Was running but over heating and knocking. engine just shut off and now will not run.

Oooh...sorry. Overheating and knocking together mean TURN THE ENGINE OFF NO MATTER WHERE YOU ARE. I have been wrenching on cars for thirty-five years, and unless you are in a bad part of town being pursued by flesh-eating zombie mail men, you should never continue to drive a car with these two concommitant symptoms. It is just barely possible that the engine is not seriously damaged, but I have had it go both ways. At a minimum, if there were no coolant leaks, the thermostat has locked shut, overheating the engine. If there were coolant leaks, that is the cause of the problem.
