860GT piston ring gap orientation
Posted: Tue Jul 04, 2017 3:13 pm
This old man is confused:
What I have seen when replacing the rings leaves me with an unanswered question, one that I could not foresee when removing the cylinder for refreshing.
Given: new rings (3), with a three-piece oil ring; this gives five gaps to place equally around the periphery of the piston, with care to avoid placing a gap in the thrust face area (front of vertical cylinder, bottom of horizontal cylinder).
Anyone got advice? Given the need to avoid placing a gap in the thrust face, I would then guess that I should crowd the five gaps around the remaining approximately 180-220 degrees of non-thrust face.
As always, any advice is appreciated.
Thanks in advance.
