Hey Dan, I'll bet you have a leak at the exhaust manifold to head union. If I heard what you said correctly "cccccchhhhhh", that definitely sounds like high pressure exhaust noise. Try blocking the tailpipe momentarily with a tennis ball or some rags in you hand (operant word "momentarily") to see if you can make the noise louder and get a fix on where it is coming from. You may need it up in the air and you may need a helper..Have a "ball"...Jeff

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of posponing the inevitable.
