You get to see the mains, factory, Porsche, aftermarket, but now you know.
Looking at the mains, tells you what the rod bearings look like because rod bearings are
Further down the oil system.
Remove the mains and number them as to their original location
Clean the case, reassemble

You make it sound so reasonable...
I appreciate that... Resealing it if nothing else diminishes leaks
If you look at the main bearings, and find slight wear... Would putting in new bearings and leaving the crank alone be reasonable? Or leave the originals? I ask as grinding the crank and getting undersized bearings seems a huge deal... What about polishing the crank?
With rod bearings, not sure I get the mechanics of it. If you take a peek at them, and replace with new same tension style bolts...why do you need to resize them? How do they change shape or orientation, if nothing else is changed? If it needs to be done then so be it...but why?
When you take the crank out, you take it to the machines shop and they resize. Then, you have to undo the bolts, and retighten again on the crank. How is this disruption any different than taking them off, peeking, and putting them back on. In both cases, you undid them...
I absolutely understand that a resized crank is better than one that isn't... But then, shouldn't an unresized crank with new bearings by definition be better that whatever is in there right now?
What am I missing?
