Fried Plugs covered in Oil

[lohalo]

Ok...well truck was good. Running fine with not a problem, then it just started missing. I was like it needs a tune up. Went and got new plugs and as I pull the 2 back plugs in driver side that are encrusted from tip to tip and covered in oil. The part where it sparks and then the middle plug passenger side tip was gone and the metal piece was melted half way back. The other 3 plugs are good. Truck runs like a dream. Well 3 days later the missing is back. Pull the back driver plug an its melted. Checkers gave me another plug and that one is fine. Just pulled all of them again to check. All the plugs are good, except for the back 2 driver plugs are coated in oil again. Whats going on with the truck???? Please help. Dont want to keep buying new parts for this right now when its only going to cost $100 to get my BMW back on the road.

Have your replaced the wires? Could also be a coil pack problem. Also, are there any signs of oil and water mixing?

check your pcv valve and make sure it's not sticking. and you may have a bad intake gasket sucking oil from the valley into those cyliners
