Linda, it's noisy in the way an old engine is noisy.
Doug, it's my coworker's husband, who was trained as a car mechanic, worked for some dealerships and now fixes his family's Toyotas. All he did, as explained above, was try to start the engine and recognize the sound it made as a timing belt problem that other Toyotas he had worked on had had. I watched him do it, and he did not have any tools with him.
So basically I followed jminshew's instructions but did not have to describe the sound - he was right there to hear it.
He's also a DIY'er like y'all and didn't charge me a dime to tell me this. Would it have been more authoritative if he had?
And finally, for the last time, the engine does. not. turn. over. So any solution that involves that will not help.
