smoking from engine / oil loss

[Green7mgte]

I need to touch on a couple other leaks while we are here.

as i mentioned I see a drip coming from were the block meets the oil pan. perhaps the oil pan gasket is leaking? is that common? is it a hard fix? I heard something about the removing of the oil pan is a pain in the arse. true?

what about the upper and lower timing belt over gaskets?
forgive me if im a tad scattered. just trying to find all possible suspects before I order parts and mid breakdown only to say "shit!" i need this!

so to recap. I definitely see a leak.. coming from the above mentioned.. mixed with a fair amount of smoking makes up for my oil loss. now to pin point the issue, cps o ring. check, will replace that and hopefully see no smoking. Did the #3 valve cover fix, still see some pooling, might just be from the plugs had excess oil in them maybe its coming from the valve stem seals. idk either way I wish to address the 2 above problems. good solid lead on the smoking now want to plug the dripping. any suggestions or places to look?
