Oil seeping advice

hello - on my new-to-me 87 TR, which has had engine out service including many gaskets replaced, new clutch, etc... I have found several oil seepage spots, which are enough to leave a small puddle on the floor under car

One spot is on the passenger side, at the back of the head. On the driver side, it is where the vacuum pump goes. On this side, there is just a plate and gasket. Oil is seeping there, onto the engine mount and then the floor. The bolts are tight. I wonder if I should remove the plate there and use some gasket sealer

the other spot, which I am trying to show in these pictures, is at the bottom of the clutch "bellhousing" I am not sure if the oil is seeping from the 2 bolts there, or just out of the hole in the housing. in the first picture, you can see the oil trail from those bolts. I was planning to remove the nuts and apply some sealer there, but now I am not so sure. i thought at first the oil was seeping around the nuts, but now i wonder if it is coming from the seam between the clutch cover-bell housing and the main engine block there

it would make sense to me that this leak is coming from rear main seal, although my knowledge of TR engine/trans anatomy isnt 100% -
i know those are tough to fix from the outside. Seeping from rear main seal of many rebuilt vintage engines has been common in my experience on american cars, and it is probably related to a combination of aftermarket crankshafts and aftermarket seals all not being made to perfect specs (in my opinion). i have not had much luck with over-the-counter stop leak additives. my best strategy in the past with other cars has been to intermittently clean off the underneath of the engine, and otherwise carry on as normal.

 

not sure what you mean by this? I didn’t know the throw out bearing depends on oil? So far all I know is that oil is seeping out the bottom of the clutch housing area. It makes sense to me this might be rear main seal but I would appreciate understanding if there might be more to it

 

Oh ok. I am fairly certain the leak is engine oil not clutch/brake fluid.
