Hello fellow FXers! Not sure whats going on but my FX seems to pump out exhaust smoke even after it's totally warmed up. I am concerned there could be a head gasket leak. I did do a block test for hydrocarbons and seemed to check out fine. doesn't lose any coolant or oil. There isn't any oil in the coolant that I can see and after doing an oil change there wasn't any milky residue in the oil. The exhaust just smells like exhaust, no real sweet note to it. Just can't figure out why the exhaust won't clear up after it's warmed up. It seems strange to me.
