I need some opinions about installing piston rings. When I put them on the pistons I aligned the ring gaps like this: (using the clock face) oil spacer 12:00 one oil rail 11:00 2nd oil rail 1:00 lower comp ring - 2:00 top comp ring - 10:00 Then after the pistons were in the holes, I read that the rings should be spaced 120 degrees apart. I'm thinking they ought to be pretty close, but I never like to leave the gaps below piston centerline. QUESTION... should I go back and set the gaps at 180degrees- or leave it alone? It's now or never... what do YOU think?
On a 3 ring piston I use the 180* spacing never leaving the top ring at the bottom of the cylinder. So I start with the top ring in the top of the cylinder,12 0-clock, and work down from there>>>>.
Do be aware that rings slowly rotate in the groves as the engine runs. On 3 piece oil rings I have always spaced the ends of the rails about 90* away from the spacer joint. But now it's together I would not loose any sleep!!
