I purchased the Mercedes Source Valve Adjustment wrenches and Manual soon after purchasing my first Mercedes (1984 300 D). And, faithfully, the valves have been adjusted ever since. ....Until today.. After adjusting 9 valves, the tenth one will not adjust. It is the exhaust valve on cylinder #2. I can't get the adjustment past .008in. Does this mean that the valve or seat is worn beyond tolerances? Or, am I missing a 'simple' solution? cory

My son is away at college with my 1987 190D. The trunk used to open, but lately the keyhole is in the horizontal position, the button will push in, but the trunk won't open. Yesterday he called and says that now the fuel filler door has locked itself and won't open. He's almost out of fuel and is threatening to take a hacksaw to it! Is this a vacuum problem? What should I do?

Hey there, So I've got an '84 300D Turbo, it sat for a bit (couple of weeks) with a half-full tank of B99, which then gelled in the cold Seattle weather, so I added some Diesel to it. Now it's got tons of black stuff in the pre-filter. I'm told this could be from condensation. I've literally been changing the quickly filling filter out every couple of times I drive it, to be safe. I'm not driving far, and it gets pretty black in those couple of trips. Sigh. So.... I read a few other things & places, and it seems this is an algae (fungus?) problem. I also read I should get various Biocides, and ended up with BioBor. I haven't added it to the tank yet, and have a couple of questions. If anyone can help I'd appreciate it. There is about a 1/4 tank in there now, should I:
