Anyway yes it is an interference motor and caution needs to be taken when turning it by hand. What ever piece you dropped will have to be removed one way or another. The only thing I can think of you could drop is the washer of the bolt. The reason the timing jumped is because of the tensioner. You can check out my sport trac thread for a little info and pics...
No.. we started it and the cam jumped and the head moved 45 degrees apart from the block... however when we retimed it.. i still have compression in all the cylinders...

The bolt broke on the back that holds the cam in place when we were timing it again...

nothing fell off but the last inch of the cam.. (The side with the cam bolt and cam sprocket) pops out.. and it has little teeth I put it back in.

I dont know if my head is junk now... I will post pics in a moment..

Are these bolts torque to yield?
