Ive had this problem since day one. Not even weather related for me. Most times it just happens when the car is warmed up, turned off, then back on. Happens

Ive had this problem since day one. Not even weather related for me. Most times it just happens when the car is warmed up, turned off, then back on. Happens on hot days, happens on cold days. Most chalk it up to this car just having noisy valve-train.

Dont think so. feels like something internal and can be felt on the clutch and gas pedal when it knocks
