Ok so checking piston rings while waiting for new rod bearing. I got these new rings from machinist with everything else. He told me they are Perfect Circle (now Mahle??)
Not sure of part #. They came in a Ertel box with part #'s 40787-030 and 2m694-030. Google brings up squat.
I'm unsure of ring location and orientation. From what I have read dots always go up. One set of rings has dot.
2nd set of rings has word "top" on it.
If I install these in grooves as above, then the chamfers both face same way.
I've read they should "oppose" each other?
Thanks
