TRITON V10 Engine with 4wd. Just had the spark plugs changed with Motorcraft, new coils, battery and terminals were changed, as well as the oil with Mobil 1 5w30 full synthetic extended. There is a lifter noise while idling. This needs to be fixed. In great shape these are selling at auction for $15000 and more... not asking price, sold! You can't find this cheaper and that's why you are looking at it...and chances are if its cheap and you are looking at it, other people are thinking the same thing you are. Waiting only guarantees you don't get what you want.
