Oil is mixed with benzin in oil carter
You getting benzin (petrol) into the engine oil??? I'm assuming your 190E is injected? Problem could be your fuel distributor. If you remove the lines from the fuel distributor that go to the injectors. turn on the ignition just so that the fuelpump kicks in (it only stays on a short time to pressurize the system)... there should be NO fuel coming out. If fuel bubbles out of any of the 4 (assuming a 4cyl) lines of the fuel distributor than the fuel distributor is 'faulty' and feeds the injectors to much fuel and the excess fuel washes itself past the rings into the engine sump. This can be caused by one or more of the O-rings inside between the plungerhousing and the upperbody or even some perforation in the gasket membrane.... either way the fuel distributor is not a servicable part, Bosch does not sell any kind of kit for the internal parts as the fueldistributors are factory adjusted to a certain flow and as new parts be of different thickness etc. the flow would be outside manufacturers settings. Cheapest solution would be a secondhand unit.

My 88 mercedes 190e suddenly
Your fuel pump could well be giving up the ghost.Do you hear a uneven buzzing sound from the rear?
We also replace a lot of overvoltage protection relays.Also,on that baby Benz ,don't overlook the distributor cap or ignition wires with the high humidity.Replace them with Bosch if marginal.

I own a mercedes benz
The selector switch on the side of the transmission might need a slight adjustment as it sounds like your transmission is borderline Park / Neutral. Generally the vacuum, or rather its absence, is to keep the transmission in a low gear for longer when the car is under load when accelerating; low vacuum in the inlet plenum a petrol engine = accelerating load = delayed gear up shift; on the diesel the vacuum system mimics this effect.

Its cuts off completly after runnninng 20 min,but
Check behind the distributor cap and see if the cam cover seal is leaking. When that seal leaks the car will drive fine til engine heats up the oil and it starts fouling out the distributor cap and rotor. When it cools down the oil hardens again and car run fine. I would start by looking there.

I own a 1988 190E mercedes benz, my problem is the
Ok things to check, air in system, coolant level low, cap holding pressure, leak at radiator or expansion tank, vicous fan, aux fan, A/C freon charged to allow low speed fan function, temp sensor for high sppeed aux fan funtion, thermostat, water pump, radiator cools 15 dgrees from inlet to outlet.
Check all that and youll find something wrong I am sure.
