My knowledge of an engine has come a long way since joining this forum but reusing rods that I have laying about make me slightly uneasy without getting some opinions from this forum.
The backstory on these rods is I received them with the car and the caps were there but not matched with the rod (hooray). I have been told that they can be re-matched by looking at the honing marks then tightening the rod bots and seeing if the mating surfaces are flush. Trust me I will be making matching marks on the rods and caps when this is finished but i'd like to know if it is even worth reconditioning these rods at all. Three of the rods appear to be fine but one appears to be smooth and i'm not sure if that is okay.
I will be taking these in to a machinist after matching them to make sure they are not out of round and so the new bearings have a nice surface to mate to. How much material will be removed in this process? I am looking at new ACL bearings and I do not know if the standard size will be okay or if I'd need to grab something like the .025 oversize or more.
My questions are:
1. Are the rods junk?
2. If the rods are salvageable how how much larger will the holes be after they are made round?
3. Am i safe buying bearings now or should I wait until the machinist gives me the new specs? (it's Black Friday and there are sales is the only reason i'm asking this, yes I realize i don't save anything if i end up needing to send back and replace the bearings anyway because I bought the wrong size).
Thanks for your help.
