Rebuilding a motor
While reading another post regarding installing a rebuilt motor I got to
thinking, what does rebuilding a motor involve? Replacing pistons/rings?
Seals?
How big and how difficult a job is it (outside of pulling the engine).
Thanks,
Bill

Re: Rebuilding a motor
Bill,
It's not too bad rebuilding an engine. You'll find a lot of the time all you
have to do is re-ring the pistons, replace bearings, and replace gaskets. If
the heads need work then you need to send them to a machine shop. If the
engine shows signs of a lot of wear and it's not within tollerances then you
may need to have machine work done to the engine as well...ie...turn the
crank, install oversized pistons and have cylinders bored out a bit. Don't
purchase the rebuild kit until you take the engine apart and inspect.
I'm about to tackle mine and have been researching it as well. Should not be
too bad of a job.
Good luck.

Only replace the lifters if you are also replacing the camshaft. Also,
bag and tag all the parts (or keep track of them somehow) to make sure
that everything that is reused gets put back where it was. Don't throw
anything away until the rebuilt engine is running in your Jeep once more.
