I post a thread a week ago about my Mercedes Benz 1982 300 SD having too much pressure build up in the crank case and having a lot of white smoke and after many replies to my thread I found out that the breathing tube from top of the valve cover to air cleaner was restricting that ventilation from engine. I had it fixed and even the smoke from engine that was an issue at that time is much better now. One thing still bothering me: If I plug half way (not completely) that vent tube I will have oil coming out from the dipstick tube. I check my oil level with cold engine and it is a little bid below the maximum but as soon I start my engine the oil level will show much higher than engine not running. As far I know oil level should show lower with engine running than with engine not running. I still trying to find out why it is happening. I will appreciated all comments from every one on this forum. Thanks for your help.
