Piston Ring Arrangement, ring gap every 90 degree?
What is the proper piston ring arrangement? Please do NOT answer if you THINK, im looking for the I KNOW answers.
Is the gap of each piston ring suppose to be;
STYLE (A)
going from top to bottom -
ring 1 - 12 o'clock
ring 2 - 3 o'clock
ring 3 - 6 o'clock
(not counting spacer ring)
ring 4 - 9 o'clock
STYLE (B)
top to bottom
ring 1 - 12 o'clock
ring 2 - 6 o'clock
ring 3 - 3 o'clock
(not counting spacer ring)
ring 4 - 9 o'clock
STYLE (C)
going from top to bottom -
ring 1 - 12 o'clock
ring 2 - 6 o'clock
ring 3 - 12 o'clock
(not counting spacer ring)
ring 4 - 6 o'clock
Thanks

Just to clarify, when you say 9 o clock front engine, you mean towards timing belt not front of car correct?
Just out of curiosity, wouldn't a gap every 90 degree's have a better seal vs the 3/9 oclock and 10-11/2-3?

Just found my manual for the piston gapping, and Mitsu manual says;
ring 1 , north east (2 30ish)
ring 2, south west (7 30ish)
ring 3, north west (10 30ish)
ring 4, south east (4 30ish)
ring 1 , north east (2 30ish)
ring 2, south west (7 30ish)
ring 3, north west (10 30ish)
ring 4, south east (4 30ish)

Go with mitsu. From all the data i have collected. You wont rings 180* apart and never place the gap over or 90* to the wrist pin. I did and accidentally scored my bores. After i noticed i repositioned them and it smoothed it all back out. Sadly i noticed to late and my bore is more then spec for out of round/cylindricity. Its all good. Its time for build number 3 to come to life.
