When and if you replace the seal, take note of the depth that the seal is installed. There is an oil passage in the cam cover that can be blocked off if the replacement seal is not seated to the correct depth.

Thanks YD, I haven’t reinstalled the exhaust yet, so I should probably pull the nose cone and swap this seal. I’ll check the depth carefully!

I don't believe it's necessary to remove the nose cone to pull the seal.. As for setting the depth of the new seal, I would just make sure that it sits flush with the outside of the cover and not in all the way.. In the great pics that Rufus posted you don't want to partially block the oil return port..
The only oil passage in the cam bushing is the feed. The drain bore is in the housing.
The seal installs flush with the outer housing bore. If you drive it all the way inboard, it will effectively block the drain.
Yep. Upon further inspection, I was talking out of my ***.
I forgot that there is a shoulder in the nosecone that separates the bushing from the seal.
Bushing gets pushed hard against that shoulder from the inside. Seal gets mounted flush.
Between the bevel on the shoulder and the radius on the seal, you probably won't block that drain port even if you drive the seal home, but since flush is good enough, that's the way to go

Thanks I didn’t know this was an option.
I found a video online where they drilled a couple holes in the seal and used screws to grab onto to pull it out.
Is there a better way?
