05 outback 200K miles puddling oil.
Yes I have had external HG leaks for quite some time but all of a sudden, there was a lot of oil leaking.
Watched a number of videos on replacing the valve cover gasket and plug seals. Today I investigated how tight the quarters are for my fat hands and to my amazement, the lower front bolt on the drivers side was so loose I could turn more than one full turn by hand!
Checked other bolts and they seem OK (alright, I didn't get to the lower rear bolt). Will check that another day.
Fingers crossed that fixes the leak... for now.
