Need help quick, installing main bearings

[insdtanoodles]

The bentley manual says to put a shell in the #4 block slot without an oiling hole/groove. Why would they says that when there is an oiling hole drilled into the block underneath, the oil comming out from there wont be doing anything, am I missing anything or just go do what the manual says?

I have the bentley in front of me and it is an obvious misprint, should read "(also no. 4 cap shell on diesel engines)". All the caps on diesel engines should be fitted with shells without oil grooves and all the block caps get shells with oil grooves/holes.

 On gasoline engines only the #4 cap gets a grooved shell. Some (correction, most,) parts outfits will sell you gas engine bearings for a diesel so you will have too many grooved shells, you can argue with them all day or just buy two bearing sets to get the proper number of grooveless shells...

there are so many different directions floating around, I installed mitchells on demand and it told me that 1,2,4,5 caps were solid and 3 had ol groove.

The mitchells info is wrong. It's always the #4 bearing that gets the 360º oil groove, but only in gassers. Diesels are all solid shells in the bottom (caps) and all grooved shells in the block. I get my info from ETKA and from tearing apart numerous factory assembled engines.
