Angry Engine Knocking!

Ok i noticed today at about 3 grand on the tach that the engine starts making a knocking noise, I drove it home trying not to get past 2k rpm. A friend told me that the valves need to be adjusted in it. But i also think that the O2 sensor is gone because it has been running very rich this past weekend. Do you think that the vavles need to be adjusted? Could it be the engine leaning the engine out to much to compensate for the rich conditions? Will my warrenty cover this, i got about 21k miles? Is this something really serious? I'm really pissed right now cause i won't be able to go up to the Beech Mtn Hill climb this weekend and be stuck in my house for the next week?

Your warranty WILL cover this, unless you have a turbo or such. To the best of my knowledge, the valves need no adjustment on our cars. I doubt that its something major. When I first got my car, at about 500 miles, I got a really loud knock that sounded as if the motor was gonna shoot a connecting rod right out of the oil pan, but as it turned out, it was just a bad timing belt tensinoner. Take it to the dealer, they'll fix it! Also, you might wanna take off your intake, so they dont panic and give you a hard time.

I may be wrong, but I think that the valves don't have to be adjusted till about 90k. I think that's what I read in the owners manual.

There are numerous cases of what you describe, and 90% it is the timing belt tensioner.
