definetaly sounds like u have a hole in the exhaust system.

 

how likely do you think it is that it's coming from the exhaust manilfold??


ps, i'm just getting an idea of where to start. If that areas a common problem, then i'll start there.

 

many people's exhaust manifold's have rusted so bad that they corrode and cause holes..........u should take off the heat shield and visually check it......also ask your wife if she has hit a speed bump pretty hard lately.

 

put the car up on a lift or ramps, run the engine and cover up the exhaust tip slightly while someone goes under and looks for the leak.

 

ya, thats about the direction I was headed. Are there any decent places that have reasonable prices for cat-forward stuff??

 

ok, so I got the car up on ramps and as soon as I crawled under, found that there was about an 18" section of pipe that ran from the bottom of the Exhaust manifold-under the oil pan and connected just about underneath the firewall. The flange under the firewall has come loose from that 18" piece of pipe so the exhaust isn't even totally making it out the back. Any ideas if that piece is available for replacement and if so, what it may be named for part number sake....

Any help would be greatly appreciated

 

bump....help!!!!

 

Any muffler shop can fix that problem for you. You might even be able to do it. What has come loose on the flange? Was it the nuts that are loose, or is it that the flange studs broke?
Your best bet would be to just take it to a muffler shop. They might even inspect it for free, and then let you know whats wrong.

 

the flange is still attached to the bolts, but the pipe has rusted apart from the flange.

 

also check the pipe between the manifold and cat. mine rusted there and made a small hole but i patched it up. the manifold is known to rust too though.

 

I hate it when that happens. One of my friends' civics had that exact thing happen to it. The easiest solution may very well be a trip to the muffler shop (could be the most inexpensive too). With a short length of tubing from Pep Boys and a bit of work you could probably do it yourself. But there's no guarantee that they'll have the right diameter piping and if you aren't at least a decent welder, you're in for a lot of fun. Good luck, and hope things turn out for the best.

 

that pipe rusted thru on my car, a trip to the junkyard and 20 bucks later it was fixed, not a difficult problem to solve either, I would actually look around for a b14 that somebody is parting out on the forums, they may be able to help you for a good price!

 

check your gaskets.. just a thought.. Travis
