my fiat brava is making a tapping noise i think its the tapids i was thinking of putting so engine flush thru the oil b4 doing a oil filter change. anyone no if this will help and any advice on which product to use and how thanks.

Try Forte Engine Flush. Forget what is written on the label. Add it to the oil in the engine, drive it for a couple of days and drain oil as normal. Replace filter and fill up with oil as usual.
