Didn't get one marked NOK - but got one that looks like NOS from czny , otherwise the seal looks identical to the stock one - and everything looks right including the little angled "oil deflection ridges" going towards the lip, which I assume "pushes" oil back towards the motor? (I - was NOT impressed with O'riely's "National" generic with no "deflection ridges" . The crankshaft seal from czny looks just like the cam seals I got out the 20 year old "last gen" box of seals a reputable full time "Subaru only" mechanic I was considering for this job (Raffi Motors ), he's the one offered to do it all for $1000, and said that's more than the cars worth.. probably true - but if I get another 100k (or more without major problems) I'll be real happy! Here's how I seated the seal.. got it level and flush with the case - used the old seal as a spacer while I very slowly turned the ratchet with my other thumbnail in the gap (at the edge) between the pair of seals and double thick reader glasses watching it move. and I KNOW it's level!
