Running through problems with my daughters truck. She traded a wore out 97 for it, with a "bad" motor. Timing chain guide disintegrated causing the passenger side chain to bind the gears.
When we got it home, attempted to repair the timing chain, and timing. Found the motor was seized.
Removed the cams to reset the timing, basically starting from scratch. Motor still seized.
Removed heads to rule out valves. Motor still seized.
Flipped it over found several rods seized. Rod bearings are pretty chewed up. Bearings still have Ford emblem on them so I'm pretty sure everything was still stock.
Crankshaft pretty rough where the Chewed up Rod bearings were.
Questions are:
Can I just have the crank cut and then just replace Rod bearings? Or main bearings also?
Or should I have a shop do the crank and all bearings?

 

Based on your post, the old 97 was in better shape than what you got now.
If you don't do things right issues will keep coming back to haunt.
There is a lot of work involved each time you need to continue repairs to the motor.
Sounds like a loss of oil pressure has caused the problems.
That means a lot of wear in other places.
Cam bearings for one. Need oil pump, timing chains, chain guides etc.
My position is the motor should be totally rebuilt, then the chances of continued issues are largely eliminated.
Over a long period of time you will be the who has the hassle and still the expense will pile up.
Have the motor rebuilt and be done with it.
Good luck.

 

I agree, looking at it now, the 97 was in better shape. Originally, no one believed the motor was this bad off. It was originally thought that the chain guide gave up, causing the chain to slip and lock up. But, that all hindsight now.
Once I started tearing into it, I had already planned on replacing timing chains, gears, guides, oil pump, and all new gaskets. Planned on main and rod bearings once that issue was found. Once the bearings were removed from the crank, that's when I noticed the journals were in need of work also.
