I have been working on paint (it's been a slow process), so my 1980 A/T has been not been driven in months. I pulled the car out of the garage last week and found quite a puddle of oil. My rear main seal is leaking, so I had a piece of cardboard below is to catch the drip, but it was completely soaked. I assumed the rear main seal had completely given out, but after pulling the car back into the garage and placing a clean piece of cardboard, I found I have at least 3 leaks (the rear main seal, a power steering leak, and an oil leak on the front driver side). The rear main seal left only a few drops, the power steer left a few drops, but the front oil leak was rather heavy. Oil coverage is heaviest on the driver side of the oil pan. A little bit of oil was present inside the lower time cover below the pump. I have removed the timing covers, belt, crank gear, and oil pump gear. The seal looks clean, but I do see some oil below the pump. Below are pictures of the pump and front main seal. The source of the leak is not completely clear (pump O-ring or the lower bolt).
I completed a timing belt change in 2017 including a front main seal, oil pump rebuild, and new cam seals. I have only put 2,500 miles on the clock since I completed the timing belt replacement. The oil pump bolts do not have concave washers, and have been sealed with Loctite. I would expect the bolt would have left more oil inside the timing cover, not behind the rear timing cover. Should I pull the pump and reseal it, or just get the bolts installed correctly? Also, why would the oil pump leak to such an extreme while the engine is not running? I'm concerned I am missing another leak. Is there somewhere else I should be looking?

Thanks in advance.
I was trying to find my small oil leak (wet lower timing cover) on my 1980 EuroS AT and I think I found a match.
So I probably have the same issue... also the metal bracket which holds the power steering pump is also greasy at the back.
believe it or not there are 5 seals on the oil pump. one large o-ring around the outside. the shaft seal that can be seen on the front. 3 o-rings under the 3 bolts and washers.
