changed the oil the other day...noticed i have a leak today...i think it is coming from the relief valve or pop off valve on the canister type oil filter...what is this relief valve for and how do i stop the leak?? didnt notice it the little valve was threaded or not...what exactly does this oil filter do? it has a rubber hose that connects to the side of the block....
