I'm currently in the process of measuring the parts from my engine to see if they are still in spec to rebuild with, and I noticed that every corner seal pocket has a tiny chunk of metal missing from the back area behind where the spring sits. They are all the same size, but the area of the pocket they are in differs. I attempted to search and find something similar to what I'm seeing, but was unable to, though that could be because I suck at searching. The only gouge I'm particularly concerned is one that overlaps with the apex seal slot. I'm going to attach photos of that corner seal pocket and one other pocket. Help would be greatly appreciated! (Rotors are from a used JDM engine (should have ~70k miles) I purchased a year ago and got lucky with, just now rebuilding it since I have been at my new job long enough to be comfortable with the expenses involved). I'm posting this right before I leave for work, but if any other information is needed I'll do my best to get an answer on my breaks, but if any other pictures are needed, it will have to wait until I'm off and back home.

 

Those are fine - just grooves from where the spring sits. As long as the corner seal moves up and down and doesnt bind when you press on it, you're set.

 

Thanks for the response! That is what I had been thinking, since there isn't anything else I could think of that could cause that to happen. There is also similar indentations on other areas of the rotors, but it's only where the springs contact the rotor. I wasn't super worried about it, since it is all behind the seals, so I imagined it wouldn't have affected compression in anyway once it's together. But, since imagination won't make tolerance issues go away, I figured it was better safe than sorry, so I posted this. Thanks for the help!
