You probably have a bad oil seal on the crank pulley and it needs to be fixed immediately.

Thanks for answering and yes is in that area. How would I go about fixing this problem would u know?


You have to pull the fan belt off and remove the pulley and then the seal and install a new one. Access is probably quite tight and if you are not a competent shade tree mechanic I would recommend that you go to a pro.
