Your going to have oil underneath the seals at the shims and locaters or spring cups, that is 100% normal.

Did you have the guides checked by a competent machine shop that told you they are worn?

I can see the oval hole in the guide. Plus the one picture shows oil seeping into the chamber after I removed the guide. I'm taking them to the machine shop to have them checked anyhow.
