The muffler on my 240 went bad, so I had to replace it (I wanted to get a preformance, but I didn't have the funds), so I go to my local muffler shop, and they do a good job replacing it (the pipe was bent just the littlest bit too far to the left, but no problem.. it still looks good ;)), anyway... so I'm driving it home with my dad, and I start to hear the "baseball card in the bicycle spokes" sound brought up in another thread... my dad thought it was the valves clicking, and then stated that my car was still a bit too loud for just having the muffler redone.

I get my car home, and pop the hood, and start to check out the exhaust manifold, thinking there might be a small leak there that we didnt hear before. Bingo. A bolt broke that was holding the manifold in place. All the backpressure from having a muffler without any holes was too much pressure for it (please, excuse the bad pun).

Anyway, now that you have all the background info, does anybody know how hard it is to replace one of those bolts, I mean drill it out and put a new one in?... They are all rusty so I'm pretty sure I'm gonna have to replace them all since they'll probly break soon anyway. I'm a low- average level mechanic, should I attempt this job myself, or take it to a shop. Also, if I take it to a shop, approx. what will it cost?

Thanks for any info, I need to get this done, 'cuz my car sounds like and old jaloppy with the valves clicking all over the place.

I did it in about an hour, id post pics but my camera broke. Anyway all I did was drill three holes in a row about half a cm into the stud and then used a flathead to turn it out.

So it wasn't too incredibly difficult. Cool!
