hey guys just a little update, i replaced this gasket, at first the job seemed impossable but after workin on it it actually wasnt bad at all, took me about an hour.
this gasket was indeed the problem, after replacing it the leaking stopped which is awesome cause it was pretty much pouring out a quart or two every couple of days.
yes it was leakin from above the oil filter but just below the exhaust, thanks to everyone here i have now solved this issue, ive read this is a very common thing to happen to 4.6's.
well worth the fix not to mention the drive way is looking much better lol!
also had to put in new anti-freeze,oil and oil filter to do this job. the oil filter adapter gasket was like 6 bucks at advancedauto.
air silencer removed, dorman intake manifold,clear corner lights,psp with psp windshield mount,blue led moded gauge cluster.
