Mercedes Benz repair: mercedes....petrol mixing with engine oil, airflow sensor, plug holes

Question
what would be causing the petrol to mx with the engine oil, also the car takes a long time to start as if the petrol not getting through right

Answer
your lucky I just fixed this problem . First thing to do is drain your oil refill. Put new oil in then take out your plugs. turnn over car if a mist is coming out of 1 or 2 plug holes your injector to that cylinder is fried if all are shooting out gas then your regulator is bad or your distributor is bad you will need to adjust your airflow sensor to the highest position 4mm alln screw you will need to take off airflow sensor. It is an easy fix also on your fuel distributorwhen you unplug from your injector lines if there is any gas in the holes where ther is an injuctor line going in your distributor fuel is bad. If you have anyproblems I can walk you through step by step but a year and class would be helpful lol
