I need to adjust the valves on my 1983 300SD Trubo Diesel. My friend and I removed the valves cover and measured the current calibration. What we found was that all the valves were adjusted at approximately .010mm. I did not recalibrated the valves because we could not determine which valves were the intake and which were the exhaust. If I stand in front of the engine (from the timming chain) can someone tell me wich is the intake valve and wich is the exhaust. I appreciate any advise. Thanks
