any help will be great.

i also pulled the starter and the flex plate doesnt look bad.

in the AM i will drain the oil.

i can see it now i will tare down the whole engine in the truck before i find what is wrong....

this is the biggest thing in my oil...there was not much of it. (the blue is a glove and the little brow item felt like grim or dirt or metel shavings


i couldnt find anything wrong or that looked different then the rest of anything. to see all the different pictures go here: Ford Trucks pictures by bradycouchman - Photobucket

As the process continues you will end up taking the timing chain cover off to see if the chain broke. You have have a busted gear or chain and a piston is up against a valve.
You could loosten all of the rockers to see if they will free up a piston. Once all of them are loose are removed, it should isolate the valve train from the equation.
If the engine turns after that, you can then remove the timing chain cover to reveal what went wrong.

thank you, i will let you know, but i think mine would be rebuildable (atlest get a core charge back)

I would have to agree with 75F350 - loosen of the rockers one cyl at a time and try to turn the engine over by hand. But i think that you'll find a few may be hanging up if the timing gear/chain has failed. Good luck!
