so i have a 190e 2.6 with a spun bearing the crank journal definately needs to be reground. the other option is to use the donor 3.0 engine I have for parts. as far as I know all the parts are the same between the two engines except for displacement. the crank should be the same so I should be able to just swap them out with no problems. as far as I know any input would help.

Thank You!

Is the 3.0 engine toast? Putting the 3.0 in place of the 2.6 is a great upgrade.
