Been using Napa Gold 1085's on my 4.0L Jeep motor for sometime now.The number on the dome of the filters are 102706C1 then below that number is this number 08:07 and these filters are leak free.Put on a filter with number 072106C1 then number below that one is 10:25 and it leaked at the crimp seam pretty bad.I've been watching it for a couple of days now and viewing a Jeep filter is pretty easy and it's NOT the gasket at the block it's the seam around the filter that is crimped to the base.Put another filter on with the first number and will get back to the board...Pete C. whatzup wit dat?
