Expedition Spark Plug Blowout
The Ford dealer in Wyoming where we spent 5 days of our vacation unexpectedly told me that it was a very common problem. After replacing the cylinder head (and the exhaust manifold which broke in the process of removing it) and shelling out $2,200.00 for the repairs and $350.00 for lodging I was on my merry way.
I initially though I had blown a cylinder head gasket, but the mechanic who worked on it told me it was a blown spark plug on one of the rear cylinders before he even opened the hood. This same dealership had experienced several other instances of this same problem within the last year. They refused to try putting in a Helicoil as they would have to remove the head anyway to get at it.
I had zero success in getting Ford to pick up any part of the cost. That was my 6th new Ford purchase and my last.
