Has anyone ever had an issue with their OIL FILTER ADAPTER. I brought it to a mechanic and that where he said the oil was leaking from. I am leaking about 1/2 quart per month. So it is a pretty good leak, and making a mess underneath! Looking to see what it should cost to fix. i was quoted somewhere around $250, kinda sounds like a lot to just remove it and replace a gasket or something.... any help would be appreciated!
