I just got a 1979 240d with 190K on it and checked the valve clearances. They were .00mm intake and .20 exhaust. I adjusted them to .10 and .30 respectively. Now when I open the oil cap with the engine running hot air and smoke comes flying out. Is this normal?
Also if the oil cooler where taken out by means of cutting and clamping the lines what effect would this have on the car?
