My friend has a 1999 Toyota Camry CE, 5speed, 155, xxx miles, 4cyl. She recently told me that while coming off the highway the vehicle stalled out. After pop-starting the car to get it back going while coasting, a severe knock from the block or head developed. Upon checking it this afternoon the car starts with minimal effort and runs ok but making a very loud ticking/knock. Unfortunately my diagnosis skills are no good for toyotas and we have no idea what it could be. Im thinking that because it starts and doesnt shake like its out of time its not the crank or the cam(s). Any advice that you can give me as to what the problem is and how it can be fixed would be great. Thanks in advance

Just because it is smooth doesnt mean the bottom end (crank, rods) arent hurt. Is the noise a slow knock or a fast tapping?

Its a faster tap. Being only an amateur mechanic I couldnt give her a definitive answer. Do you know what it is? Thanks again for your help!

Faster tappping noises are usually related to valvetrain. See if you can determine if it coming from the top of the engine or if the noise is louder under the car

I would say it is definitive that the sound is coming from the top. As soon as I heard the ticking sound I thought it would probably have something to do with the top end.
So would you advise that I take the valve cover off and inspect for any visual damage? And what specifically should I be looking for? Any other advise or diagnosis would be great! Thanks once more

Yes, pull the cover off and look for any of the cam followers that may be loose under the cams. You might want to pull the plugs out so you can turn the engine over by hand to inspect the valvetrain
