I bought a set of pistons .5 over and am a bit leary about the rings that come with them. I thought the top ring was a special chrome-moly ring, I'm just trying to recall this from memory. I looked on the forum, but I don't see anyone mention something like this. I wonder if you can help- will they all look the same or is the top ring a darker color. Just wondering if I should spend some $$ and get the right ones for a TD rebuild.
All mine looked the same and they are crap. They were also $9 per set.
they all look the same, but they are shaped differently. the top ring is smoothe. the second ring has a little bit of a lip at the edge. the 3rd ring is 3 pieces. that help any? oh yea, the top and 2nd rings have the word "top" or "up" on them. make sure to put them on the right way.
I bought pistons and they were alreay installed on the pistons. I guess a guy should check to make sure they are correct. Thanks! Has anyone tried the total seal second ring? Is there any difference since this is a diesel with total seal?
I have the complete total seal set on my pistons, I cant vouch for them since the pistons aren't installed yet.
I did not like the top ring total seal sent me. The rings that came on my German TD pistons were a nice set, so I kept the nice chrome-plated - smooth stock ones. The total seal top had no roundover on the edge, stocks are beveled.
3rd (oil) ring should be two pieces, it should have a wound spring inside.
