So on my 87 camaro with the factory 350 I have a pretty large exhaust leak at the manifolds and where it bolts to the engine. The question is, how do I go about changing the gaskets and such. Is there anything I need to remove to access the bolts or to change the gaskets? Everything under the hood is stock so I still have all the smog equipment and A/C and such.

 

Done some searching and there has been some back and forth on whether or not these cars actually have the gaskets on the manifolds or not. Can someone clear that up?

 

My stock exhaust manifolds in my 88 had no gaskets.

 

IMO have you checked the tube running up from the Cat. it just seems strange that the manifolds would start leaking unless they where disturbed.

 

Are you talking about the AIR tube? If so I will check it out in the morning. As far as I am concerned they have not been touched, just sort of started after this last winter.

 

That's is it, I don't run a cat and forgot the name. IMO I would check the air tube and the joint were your exhaust attaches your manifolds before attempting to remove them.
