Hello,
I recently had a new catalytic converter replace in my '07 Vibe.
The mechanic thinks there is a hair-line crack in the manifold; he can hear it but he can't see it. He suspects its where the individual pipes come together though.
I'm wondering if it could be along weld joints. Is there any way to determine where the link may be?
If I can find it, would something like JB Weld or a similar steel putty work on it?
My mechanic suggested replacing the manifold ($280 for the manifold, $100 labour) but I don't really want to spend money right now since I just replaced the catalytic.
Thanks.
