I figured I would give this section of the forum a try before I give up on it once and for all. My '85 300 D turbo, CA emissions model, has a sound coming from the engine that sounds exactly like one of the valves are loose. I have checked, adjusted and rechecked the valves and they are all to spec. The "click" is engine speed related and seems to be louder when fully warmed up. Strangely, the sound can be best heard from the drivers seat. I have not been able to distinguish the sound from all the rest of the sounds that from under the hood with and w/o a stethoscope. I have checked for loose, broken or leaking items and everything exteriorly on the engine appear fine. The car otherwise runs good and has as much power as it should. The oil pressure and coolant temperature are both normal. I have run out of things to check and I would like to try fix this problem myself before taking it to a shop. Is there any technical expert out there that can help me?
