this may be a silly q's but which way do A series rotate looking from the front of the engine?

also with the ring placement, when it comes to the oil spacer ring where do the top and bottom ring go for that? ive read somewhere 15 degrees either side of the oil spacer gap.

as you can see with the image, the 1st and 2nd ring are 180 degrees from each other and the oil spacer ring is 90 from either one. so where do the other 2 rings go that are with the oil spacer ring?

Nearly all automotive engines rotate clockwise. The most famous exception is Honda engines

thought so, any ideas on ring placement DD? So many different diagrams online, obviously i want to get it right as im doing assembly this weekend.

There is several ways to "do it right", which is why you'll find different diagrams. All the ways involve staggering the gaps. For the oil rings I don't think it matters as long as the 3 pieces have the gaps at different spots

My Datsun 1200 factory service manual (1973 edition) doesn't seem to cover this, you would normally follow the ring manufacturer's instructions

in the image above is that saying the compression ring and oil ring are in the same positions? that diagram is out of a b310 A15 FSM which is the engine i have.

The "oil ring" is three pieces:
* Oil ring top rail
* Oil ring spacer
* Oil ring bottom rail

That Nissan FSM has a circa 1980 recommendation. Your ring manufacturer may have a slightly different suggestion. Either way will be correct

so where do the compression rings go then?

Good question, that diagram could be better

The compression rings are the Top ring and the 2nd ring. Nissan recommended lining up the Oil ring rails gaps with the compression ring gaps

Perfect that's what I thought. The diagram could definitely be labelled better. Thanks again for your help DD

Another question is what is the "thrust direction"? Is it the left or right side of the engine? I can't remember
