Thank you for the replies. I did clean the engine as best I could with those spry can engine cleaners to try and see where the leak was coming from. I wasn't completly sure it was from the top timing cover. I was thinking to replace the seal as a precaution.
The O-ring that is mentioned, is this the bolt that holds the Y-shaped bracket for the PS pump and the long bolt that mounts the belt tensioner? I didn't remove the Y-shaped bracket from the front of the engine only loosen it. I didn't notice an O-ring. Is it between the bracket and the engine or between the head of the bolt and the bracket?
Maybe I will have to pass on the front crank seal as I don't have a torque wrench. I don't need more problems caused by not having things tightened correctly.
Do you think if it were the crank seal the oil would be on the back of the harmonic balancer? It does seem to be dry. It's just the oil down the front of the oil pan that is really noticeable after the car has been running. Do you think it could be the oil pan gasket or would that leak all the time? Thanks again for your help.
