1981 300D Intermittent Starting Problem

I am currently dealing with a very frustrating starting problem with my 300D. This is the symptom: I turn the key in the ignition and sometimes it will start and sometimes it won’t. If it doesn’t start I proceed to turn the key between the off position and the start position. Eventually it starts, sometimes after doing this once, sometimes after 10 attempts. At the beginning of this problem, I knew nothing about automotive electrical systems, so I thought it was the starter and replaced it with a remanufactured Autolite starter from Kragen/Checker Auto Parts (I know this was probably a bad idea). Well, the problem continued and since I already dropped off my (probably) good Bosch starter for a core refund, it’s too late to go back.

Adjusting the Idle on a 1981 240D

After doing a valve adjustment my D gear idle seems to be a little low and the engine shakes a little more than it used to. I am pretty sure the adjustment was done properly but for some reason I get a little more shake at idle and I was wondering if anyone knew how to adjust the idleon the 240D 1981 Autotrans mercedes?? Has anyone seen this before?

240D Auto Transmission Shifts Prematurely After Valve Adjustment?

I have a 240D 1981 and I recently performed a valve adjustment. The adjustment seems to have gone as planned but when I began driving it I noticed decreased power due to the fact that the tranny was shifting too early on all gears now. I may have 1st of all done the adjustment poorly or may have messed up some vacuum lines to the tranmission shifting system which I don't understand too well. Anyone have any hints?

79 240D oil leak on shoes while driving

oil is leaking into my car from somewhere up under the dash/cluster, and drips down onto the brake pedal and my shoe, and while it is not a huge leak, it is a messy pain in the ass, and i would love to figure out what is causing it, and fix it. i have tried looking up behind the dash, and it seems like pretty much everthing is coated in oil, and so it is hard to get a sense of where the leak is coming from. someone had suggested a faulty oil pressure gauge. how difficult of a repair job is this? do i need to take the dash out to solve this problem?

alternator on '77 300D - not charging battery - or battery prob?

It appears that the alternator on my '77 300D is not charging the battery anymore, or the battery is not charging via the alternator. I took my alternator up the other day to Schucks, they tested it and said it was fine. After driving a while, the battery-dependent electronics show that the battery is dying. Last night while my 300D was running, I disconnected the battery leads from the battery and hooked my multi-meter up to the neg and pos wire connections (not on the battery). The voltage was in the range of 10.xx to 11.xx volts. Now I'm no mechanic, but shouldn't it be higher?

300TD Wagon - Water in the rear hatch!

So today I drove my 1985 300TD wagon to work in driving rain. At the end of the day after it stopped raining, I opened up the rear hatch and when it was open, water poured out from the molding on the inside about half way up the rear hatch. I am assuming that the rear window seal leaks and I should probably have it replaced by a glass shop. I was also thinking of drilling a drain hole in the bottom of the rear hatch so that if it happens again the water won't fill up in there again.
