Main and rod bearing oil clearances! NORMALY, FSMs provide oil clearancesc given in a total amount (both sides of crank added together) subaru gives u clearances for one side. This is because we have flat fours where oil is coming in from BOTH side of bearings as opposed to just one side on inline and V type. Subaru engines are really quite easy with ebough practice. Ive never rebuilt subaru before this feb. Since then ive built 5. Lol. Goodluck with proj! And I suggest upgrading yo allen head oil separator bolts!
