Engine Replacement
I have read numerous posts here about people who have replaced engines with junkyard motors.
This is certainly not a bad thing but my thought is that while the motor is out, installing new bearings and rings and of course, the requisite gaskets is both fun and good business and quite inexpensive. Once an engine is out of the vehicle and on a 29.00 engine stand, they are EASY to work on.
My favorite part is installing the crankshaft into its new bearings in the upside down engine. to feel that heavy crank turn effortlessly in its new babbitt is a real thrill for me. But I am easily amused.
While I know crank journals can wear out of round,I have never seen this, just install standard bearings and enjoy.

I agree it is a good idea to pull them apart and replace bearings and common wear parts before installing them, I have a friend who kept going through 3.3L engines in his plymouth voyager (3.3's eat up rod bearings) I finally lectured him and told him 'Since you go through rod bearings like that in used motors WHY DONT YOU PUT NEW ONES IN before putting the motor in your van?" so he just went all out and rebuilt the whole motor! its knocking again though (typical chrysler)
