k, so im going to be fixing an oil leak on an 88 legend and the owner was told (from firestone) that it is an o-ring where the oil filter mounts. pretty much just need to know about how long of a job this is. i dont remember there being an o-ring there but i was thinking it may be the whole part the oil filter screws on to. any ideas? like i said, i just need to know about how long the job would take

 

shouldnt take 10 minutes tops.
