Much more likely to be the front seal! I have never seen one of those oilpans leak!
The "front" seal is right behind what you are calling the flywheel.Definetly not the oil pan. Where’s the front seal again remind me
If you remove the front pulley (flywheel) be sure to mark it so you get it on again in the right place. It has timing marks on the front under the attachment bolt but they are hard to see in the machine. It will have a bad vibration if you get it on wrong ( It is splined to the crankshaft) The seal is removable from the outside after the pulley and the small sleeve inside the seal are removed. It can be quite contrary about coming out of there but it is doable!The "front" seal is right behind what you are calling the flywheel.

There is no need to remove the front cover. This is actually a very common problem on that engine. You will find the seal very brittle and the rubber part partially detached from the metal part of the seal!
Should be no problem doing it yourself. I use the engine starter to loosen the bolt on the end of the crankshaft. I put a wrench firmly onto it and firm against the machine frame then hit the starter. Be sure you consider which way the engine turns! That bolt can be quite hard to get loose otherwise because there isn't an easy way to hold the engine from turning and it is awkward getting an impact wrench up there! It doesn't take long to change the seal provided it doesn't fight too hard when you pry it out of there. Just be careful that whatever you use to pry with doesn't gouge the aluminum front cover.Thanks for the advice . I finally have a copy of the wsm so hopefully I can tackle this job myself.
