hey all... my gf has a 1.8 16v zetec silvertop in her mk6 essy cab and think the wrong oil has been put in at some time... not too long back she was complaining of a sort of tappy noise so i checked the oil and yes it was low.. so topped it up but still taps... is it a sticky lifter?? or could it be something more??? would an oil change using the right gear sort it out?? or would it need something a little bit more than that??? only sounds like 1 or maybe 2 lifter??? any idea peeps??

CHEERS!!!
