I recently replaced the head gasket on my BF 90 and when we put it back together, we tightened the timing belt too much. This caused a small oil leak around the upper seal on the cam shaft. Do I need to pull the head off again to replace that seal or just remove the old seal from the top? I've already ordered the seal from boats.net and expecting delivery any minute...but is there any other parts that I may need? Thanks.

You should be able to replace it without removing head again.
