Help needed!!! Oil leak coming from tensioner bolt hole

[mitsumissile]

I had a shop changed the timing belt for me. Yesterday they finished the car and start it.
They found there is some oil leak coming from under the car and they shout it off then check. After they check it, the mechanic told me the oil is coming from the timing belt tensioner's bolt hole. They put some glue on the bolt and screw it in. Then they start the car and it didn't leak now. My question is why does the bolt hole has oil? The oil is spary out. it has presure. Thanks
