hi have developed a very rattly noise from top of my agg engine(mk3 gti)- on closer inspection it turned out to be a plastic shield/baffle? just under the rocker cover- this appeared to just sit losely over the threads that protrude from the tops of the bearing rings, ive had the rocker cover off and removed it, solving the rattle nicely!- but can anyone advise as to if i can/should run the engine without this part? from what i can see it just prevents oil spraying up if you remove the filler cap whilst the engines running, any advice highly appreciated!
