Having trouble figuring out how to ask a text question. I apologize if this is not the correct method.
I have a 1995 850 wgn non-turbo. I am changing the timing belt and have discovered two sets of marks on the camshaft pulleys. One set is an uppercase “M”. The other set is painted on by someone before. My dilemma is this. The letters are punched in a similar location relative to the holes punched into the pulleys. The painted marks, however, are not. The one on the intake is between two holes; the other is on a hole. This seem wrong to me. Other than the letter “M”, I cannot see any alignment mark on the pulley from Volvo. Another problem – neither set lined up with the marks on the cover when I took off the timing belt front cover.
My questions are: 1) Is the correct mark to follow the “M”? And should they be lined up vertically or to the notches in the cover? 2) Should I trust the irregular marks? 3) If I restart the car, and I have lined up the camshafts incorrectly, will I do irreparable damage to the engine?
