a cracked manifold, or lose bolts... the donut is where the manifold and the exhaust connect... you should be able to hear where its leaking....

Hi mcv,
When checking/replacing the donut also make sure the sleeve is there too. The sleeve is a piece of exhaust pipe about 3" long and swedged to size so it slips into both the manifold and the exhaust pipe. It runs inside the donut.
Good Luck!
Regards,
Alan

Here is a very inexpensive and easy way to track down an exhaust leak:

Take a piece of old fuel hose or heater hose, doesn't matter how long, but at least 3 feet or so. Stick one end in your ear, and use the other end to search around for the leak, kinda like a rudimentary stethoscope. When you find it, it will be extremely obvious.
