Get the service manual - it will save it's cost in grief.
The case cover is about a $60 part. Or you could remove it and try to seal the crack with J-B weld. Clean the cover thoroughly with brake cleaner, get a disposable syringe, mix up the J-B and use the syringe to inject the epoxy into the crack, clean up excess. Wait 24 hours, reinstall, cross fingers....
Or just get a new cover and gasket - bolt torque spec in the service manual.

Clean out any small bits you see and you should be OK. Get a new gasket, because for sure you'll tear the old one if you don't have a spare on hand. (A Murphy's Law thing). Post up pics as you go through and any "challenges" encountered. You may be the first to have done this repair, so your insights may be helpful to the next guy.

It appears that the cover houses the clutch and water pump. Drain coolant from drain bolt - the one with the copper washer. Drain oil.
I am not sure but there is probably a seal for water pump. I would remove water pump housing and leave hose attached. Take a look and see if impeller is easily pulled out....Then remove clutch housing. Be careful - there may be a ball bearing on end of clutch rod.
Also, ask a mechanic at a dealer. They may give insight

Sorry to necro the thread, but I'm going to be replacing my crank case cover as well, and was wondering if you had a write up or pictures of what is involved?

I'm assuming I'll need to drain the oil before pulling the cover, but other than that it is just replacing the gasket/cover and torquing down the bolts to the correct spec?

I'm only doing it to fix a cosmetic issue, nothing is actually wrong with it. (i should have bought covers).
