Exhaust Leakage Identified - Way to Avoid Replacing Exhaust Manifold Gasket?
I smacked the cat converter pipe on the driver side where it cuts over to connect with the muffler on a rock pretty hard like a goon and a week later got a check engine + trac control off lights (P0175, P0102, and P0171 errors). Thanks to the forum, I learned how to identify that I had leakage on both exhaust manifolds and the connection points to the cat converters - basically at every gasket upstream of the muffler connection.
I replaced my full exhaust system a couple years ago when I bought the car and definitely would like to not have to take it all apart again to replace the gaskets especially for the exhaust manifold, they were really hard to get to last time and it took forever.
Is there a way to fix leaking exhaust gaskets without replacing them?
I haven't tried re-tightening or some things I saw online with high-heat epoxy yet since I wanted to learn from the crew first.
Thanks!
