Test Pipe Bolt Came Loose - Serious Leak
 

As stated I had a test pipe bolt come loose. I'm out of town working and can't fix it right now. You guys think a few days with this thing leaking at the headers will cause any issues besides the unbelievable racket?

Might confuse the primary O2 sensor on that bank -- an exhaust leak just past the O2 is often misread as a vac leak, and so it may get high positive fuel trims and eventually a CEL.

Shouldn't hurt anything, but just a heads up...

I've heard some people worry about valves but I still have the header intact and I can't imagine the valves cooling too quickly after shutting down with the amount of heat under the hood.

Thanks for the input.

Thankfully, the leak is after the upstream wideband o2 sensor which means fueling shouldn't be affected too much. It will definitely throw off the downstream o2 sensor but that is pretty much only there to look for a functioning cat (*ahem* ;) ).
