Smoke behind alt?
However my question is that if I'm going to change the rear manifold gasket, would it also be a good time to clean the plugs and boots? I've only had them on for about..30k miles? Oem ac Delco replacements both plugs and wires.
And also is it good time to change my intake gasket as well? I haven't don't that I've only changed the front manifold gasket due to oil leak.
