Default Splitting block, have some questions

Hello everyone,

I am in the process of splitting my EJ257 so I can take both halves to the machine shop to have the cylinders honed and rings fitted.

I am curious if I split the block, take the journal bearings off and mark them so I know exactly where the came out of, can I reuse them when I put the halves back together?

I am trying to avoid unbolting the connecting rods and also avoid buying new bearings and I need to know if crank bearings need to be replaced anytime a block is split.

The engine has 74k miles, never spun a bearing, ran out of oil etc.

You shouldn't reuse journal bearings. You don't have to unbolt the rods from the crank to remove the mains. But you really should replace both mains and rod bearings while you have the case split.

If you already have the engine torn that far apart , you should really replace the journal bearings , and as said above do the rod bearings as well. A little extra money for some great preventive work
