Just chasing a noise on my 2.0 that sounded like an exhaust leak but doesn't look like one once the exchanger is off the head.
However I notice that the #3 port and pipes are light gray instead of black. I tightened the exhaust before taking it off with no change and it doesn't look like it was leaking there. Could leak between the head and cylinder cause it to be lean? and also go away once its warmed up? Or is this generally a problem that is cause by intake leaks? |

Could just be a leak in the muffler to head seal.
I always start with new copper gaskets. Anneal them. Hang HE loosely front and rear, then,doing all four together, I tighten the HE to the head. Then, after that is done, I hand the muffler and get that fitted and tightened Then I go back and,tighten up the HE again. Thanks for asking, feel like I had a HA.
