The bearing tabs of the connecting rod bearing cap and the connecting rod are located on the side of the piston cooling jet.

i do not know what you mean by groove. i have 5 of 6 rods with the bearing tabs on the right side of the block looking from rear of engine.i have one on the left side.when i say tabs i mean the slots that lock the bearing in the cap and rod. the piston tops have numbers on the them which are all on the right side, not 5 of 6 . if i pull out and turn around the piston will be opposite the others unless i take off rod and turn also this is as found as i have not taken piston off rods. can i leave installed as is

was it like this when you took it out ?
Expert:  Don replied 6 years ago.
yes it does matter which way you put it in they should all be in the same direction

I dont really know for sure .Ichanged the block but reusing pistons and liners which i left pistons in liners and installed in new block. i made note on the first rod cap how the tabs were oriented and didnt check all.also made note of orientation of pistons and installed with numbers on same side. as isaid before if i turn the the rod then the piston will be backwards relative to the others . i dont really want to change the piston around because they are already seated in the liner the way it was taken apart
