#1: GTi tapping, exhaust cam area Author: Mr-Tigger, Location: EssexPosted: Sat Jun 15, 2013 7:51 am ---- so i got bored and decided i'd see what swaps people offer me for the gti,next day and i think she knew as suddenly developed a tapping,on checking its coming specifically from exhaust cam cover,left side as you look from the front. it also had a fault for running lean but think thats just due to exhaust mani leak somewhere.
a mate suggested checking plugs not loose,easy enough,however also checking tappets.....this im not so sure on. ok i can get the rocker cover off,but apart from blatant damage,what am i looking for or could it be?
it sounds more metal on plastic than metal on metal and doesnt appear to have affected performance at all
