[MR2] Conrod 2 crank bearing problems:-(

[Angus Harvey]

On my mk2 1992, mr2 2000 gt i... I had a terrible knocking/rattle...
Assuming it was a bottom end bearing,  i took the sump of to investigate!
I found that the shells on no1 con rod to crank bearing had overlaped
and melted:-( the engine was only run  like this for 10mins and not
constantly!
There is obvious signs of heat cawS oil hole is practicaly gone and
the shell in contact with the crank is blackened!
Basicaly i need to know if the crank will be bent...otherwise can i
get away with putting new shells in?
 Oh and can i get the crank out without taking engine out. And to take
engine out do i have to drop the bed?

My other option is to do an engine transplant. I do have another which
is only costing me 150 pounds, providing i take it out of car myself!
The reason for it being to Cheap is cawS i cant run it up due to it
being dp'd, and fuel lines cut. The breakers never ran it them selfs
illegedly! The car was side impacted and written off.... Has been sat
for 2 years now too!

Pls help...what should i do?

A gutted mr2 owner.
