It depends?

If they are bore sized 'O' rings then they will be for the cylinder sleeves. If you haven't taken them out then I wouldn't bother. I think the manual says if you leave the block standing on the bottom of the sleeves then gravity will push the sleeves out of the block - I have not been able to remove them when using my own non-destructive force and have never gone to the trouble of getting the sleeves pressed out to change the seals.

However, if they are 4 small 'O' rings (around 12-13mm) then yes, they are important. They will be the ones that seal the oil passageways between the crank case and the base of the block - I forgot to put these in myself once!

No you don't, those large O-rings are for the sleeves. If you didn't push the sleeves out of the block, you don't need them.
