newbie question...
T Cro, what do you mean by don't knock it or the new one in the motor?
when the seal is installed, there is no positive stop, or shoulder in that bore, therefore it is possible to either push the old one in too far, when attempting to pull it, or pushing the new one in too far on install. same issue replacing the shift shaft seal, or balancer shaft seal on the opposite side....
common replacement on those is usually done by using a small drill bit in a dremel tool, and carefully drilling a hole in the face of the seal, then installing a sheetmetal screw, carefully, and pulling the seal out with pliers...
luckily you can pull the clutch actuator rod carefully out, and using an old screwdriver with a 90* bend on the end, stick it into the hole in the seal, and pull it out thatway.
that picture to me looks like the banjo bolt copper gaskets are leaking tho... not sure as I can't see where the oil really is, but those gaskets look messed a bit.
