My car has been slowly leaking oil since I got it...I used Bluedevil rear main sealer which seemed to work a little, as I don't see any oil drops on the ground anymore. But today after a good drive I stuck my head under and noticed a drop or two near the bellhousing, and also on these two tube / hose things next to it. It seems to be dripping directly from there, could this be from the rear main seal too, just getting on these hoses? What is this hose / can it be the cause of an oil leak?

Thanks.
