In cold weather when the temperature is at the freezing mark or below and the engine is started it sounds normal. As soon as the transmission is engaged there is a tapping sound that disappears as the engine warms up. If the engine is allowed to run for a few minutes after starting from cold and before the transmission is engaged the tapping sound does not appear.

    Changed the engine oil more often every 4000 miles

    Have experienced the same - utilizing synthetic oil which appears to be reducing frequency. LeslieF: Have you identified the source and a fix?
