Hello V8'ers,Have been hearing a ugly sound coming from valve cover area lately,when engine is cool no unreasonable sounds,when normal temps are reached it sound like theres rocks in the head,when engine is hot (temp gage pointing 12 O'clock) the sound backs off,any relation to the oil retension valves in the head, I know what ticking sounds like but this is not the noise (no such luck)what the heck was the factory talking about in relation to this "new information" in the Bently rag. This 91' 3.6 has a 125 thou. on it - I would like to do a hundered more .... Thank you for any feed back!
