Mercedes 300SE - Ticking noise
Hi, could somebody help me, my merc 300SE,1989 model started to make ticking noise, when is on P or D or N. Seems like it's go faster while I accelerate. I couldn't here the ticking noise while I am driving. The ticking seems to be coming from the top of the head, is it the valve (that's what mechanic thinks, without even opening the rocket) or something simpler, means not so expensive? The oil pressure is ok, and besides ticking is running fine. Anybody has an idea??
Thanks Nina
