Driving the car on a long trip yesterday i notice a ticking noise coming from the driver side rear of the engine by the rear and valve cover and rear header near the downpipe i can make a vid later on but it actually started happening when i got my exhaust welded... 3 inch speed daddy flex welded with 2.5 inch piping from the exhaust shop the welds look ok .. Could that be it? Replace rear header gasket? They are felpro gaskets fyi thanks
