'76 300D voltage regulator
Was about to replace my alternator but heard I should check the voltage regulator first. I'm not sure how to access it or what to look for to see if it needs to be replaced. Any suggestions or tips would be appreciated!

The symptom is unburned fuel at idle. A light puff-puff of black smoke -- not heavy, but visible, at 700-750 rpm with car in gear and A/C on. Much less smoke when the tranny is in neutral, A/C off, and engine is idling at 800 rpm. The presence (or absence) of an air filter has no effect. Except for this bit of smoke, which is embarrassing at stoplights, the car runs and shifts great. 0-60 in 14.5s, and I measured 10 psi boost during hard acceleration. On long trips getting 20-22 mpg (milage verified with GPS).
Recently, my oil pressure gage started reading above 3 bar at idle. Revving the engine does make it go up a little and turning off the engine drops the reading to zero. What to check, or is this a faulty gage. Oil level is good. The oil can by the gage has also lit up.
I have developed a transmission leak, originally i thought it was the pan gasket so i replaced the filter and put on a new gasket. that didnt work it is still leaking. i think it is comming from where the dipstick tube goes into the transmission, or maybe the transmission cooler line, i have tightened the cooler line and it still seems to be leaking. if anyone has any sugestions i would be most greatfull.
I'm not getting charging to the battery. I have replaced the voltage regulator on the alternator (the old regulator brushes where about worn out), but did not get any change in the charge to the battery. At idle, voltage to battery shows 11.9v and dropping. When rpm increased, voltage will increase to 12.35v max, than right down below 12v when back to idle. What am I missing?
I have a single tank wvo conversion on a 1984 300D. I currently have the following fuel routing: Fuel tank to pre-filter to boost pump to vormax fuel filter to heat exchanger to stock system. Is there a problem with me putting the vormax filter first, then the pump? In other words, is it ok if the pump pulls through the filter instead of pushes?
Thanks.
greetings,
looking at buying a 1985 300D with 173k. i am going over this very nice looking car with a fine tooth comb. i like this car. it appears to be a "loved" MB. it started right up after siting for a a year or so. all was happy until i checked the transmission fluid. it was so dark that i thought someone put rotella in it. and it stank like a burned up transmission. i have to test drive it yet, but i was leary already.
any chance that this is just "spent" fluid. or does it sound like a rebuilt would be in order?
how durable are these auto transmissions?
