I had the leak between the oil filter adapter and oil cooler that seems to be so common on my '06. The dealer wanted me to buy the whole oil cooler as they wouldn't sell me only the gasket. I declined and found a replacement on Ebay. Now about a week later and 250mi I noticed it is leaking again! Only a few drops but it looks like it's coming from the same place. The place I took it to said they would repair for free if it's the same leak. Do I need a new gasket though? Unfortunately it'll take a few days to ship and I'd rather order it ASAP if I need it. I'm sure this was the right gasket and the mechanic confirmed also. Is this poor workmanship or just normal luck of the draw and sometimes it needs to be re-done?
