oil residue on spark plugs m272 08 ml350
Hi everyone
I was changing out my sister's spark plugs on her '08 ml350 with 135k miles
all of her plugs had oil on the threads and weren't even threaded hand tight.
The tips look good so thankfully i don't think the oil made it into the head
The coil packs looked dry too so I'm a bit stumped.
Also I have looked around for spark plug seals, I don't see a diy or a part number for this. Does anyone know what the spark plug seal part number is?
