Does anybody have any information on what order the piston rings go on the 4 groove LDT pistons? Here is what I think so far:
-Top ring #1 and second ring down #2: Bevel on the inside of the ring faces up. These two rings appear to be the same.
-Third Ring down: This ring is a little thinner ring than all the others, so I know it goes here. It has a small circle stamped on the top of the ring, so I assume that circle faces to the top of the piston?
-Forth Ring down: This is the oil ring. This ring is not completely smooth on the bottom (like a castle nut to exaggerate it) and I don't know what way is up. I wish I had a picture of it, but I forgot to get one this morning. So if anybody has put these in their engine, let me know... i'm confused on how to orientate the bottom ring.
UPDATE:
The oil control ring castellated face of the ring goes down and the smooth portion points up. So far everything I have found, any dot/circle/stamp that is on the rings should be pointing toward the top of the piston. With these oil rings, I opened a pack of NOS rings and there was an ink stamping on the ring that said, "TOP". The other rings I had did not say this, but this one did... so now we know.
