I have a 92 f-150 4x4 that I bought few months ago for 800 bucks. New paint job and tires. Knew the engine had some issues but still runs strong. The thing I need assistance with is what to do with it? Has 250kmiles needs the flowing:

Head gasket
Rear main seal
Motor mounts

Should I just get used engine? Or do rear main seal and the motor mounts? Then I can do the head gasket after and bring heads to machine shop.or is it easier to pull the entire engine than to pull tranny because of the rear mail seal??? Help!!!

Your best bet is just to pull the engine and do a rebuild. Not that it will necessarily need it right now, but with the engine out and heads off, and the pan off to replace the rear main, you're just a few bolts away from having the main bearings done, and the rod bearings as well. With the head off you can take a look at the cylinders and see if they need anything. Once the block is out, the hard work is done. Throw a hundred bucks at it for bearings and gaskets, it's ready for another 250k.

Thank you!! On my way to do so, engine out and tranny out.. one more question when putting back in? Should I put back engine with tranny attached seems to be easier, other wise I could be a pain to put back each piece.. what you think??

Sorry I disagree. You can't just throw new bearings at a worn crank and expect it to last. At 250,000 everything in there will be worn.
Either just replace what needs to be replaced and stuff it back in, do a complete rebuild, or shop for a low mileage replacement.
IMHO

I redid the heads, few valves replaced and they were also seated!!

New alternator
harmonic balancer
oil pan
oil a oil pump and screen
freeze plugs
distributor
cleaned everything up
cleaned pistons everything looked good
timing gear looked great.

Rear main seal too

bostonwindows30

Yes rear main seal.. I tourqued engine bolts down and followed a pattern, noticed by mistake picture was upside down!! Will inneed to redo this? Kinda stressing out about this. Basically didn't pay attention to the arrow saying from of engine and I tourqued 2 down first instead of 1 not sure what to do. Will it make a difference help!!!!

If you followed the pattern backwards you will probably be ok. The main thing is to follow a pattern that tightens it in a pattern rather than starting at one end and working towards the other.
Basically they want you to start at the center and work toward the ends.
You're supposed to torque it 3 times - about 30 then 50 then 72 or numbers close to that. If you haven't done it all 3 times yet, just do it in the right pattern for the next times. If you've already done it all 3 times I wouldn't think you should worry too much about it - it's torqued and you worked from the center to the ends so it should be fine.

Yes I did I did it three times, following it the same way!! Good didn't want to do it again, thank you so much had me up all night....
