occasional white engine smoke
my wife has a 2006 volkswagon convertible bug with an audi 5 cylinder ,
engine. she took it in for sevice ,they put on a new valve cover and gasket,
new plugs and oil change.Since then every once and a while when she
decelerates to go thru our entrance gate and then accelerates the exhaust
will produce a large cloud of white smoke.She says there is a rattle when it
happens. Any ideas? It has 97k miles.
