HELP!!! Motor Problem!!!
I am trying to diagnose a motor problem which was granted to me on Christmas!!! The Truck is a 1996 F150 4x4 5.0L auto.
Driving down the road normal, drove about 5 miles from home and there was a loud POP! Then the motor started running very rough. I shut it down. Leading up to this I have noticed a slight lifter noise in the past week or so, other than that nothing out of the ordinary has changed.
The motor shakes terribly and has a sound like a brake rotor when there are no pads left. It will start up immediately and run still.
Is it possible that it has a busted flywheel? I have heard of it happening but never seen it personally. The noise is coming from the bellhousing area. It doesn't sound like a rod to me because its not as loud of a knocking/grinding noise.
What do you guys think??

It only takes a couple of minutes to pull the inspection cover off and look inside the bell housing.
The bad thing is, a broken flexplate will not make the engine run rough, although it can make it vibrate.
Flexplate failure was not uncommon in these years. Could also be a failed converter or pump.

No fluids leaking anywhere, It does still move just has no power at all. I haven't run it hardly so I won't make things worse.
I first thought it could be a bent push rod because I have had that happen on my 351M before and the rough running is pretty close, but I don't remember the it ever sounding the way this does.
I just haven't been up to laying in a couple feet of snow to pull the inspection cover.

With out being able to hear the noise its hard , If you think its the motor , just start it up & start pulling plug wires one at a time tell you find one that dosn't change the way the motor runs , then go from there ....Lew
