Gonna start dismantling it tonight.
Im going to try to remove the oil pan because im suspecting that its leaking at the gasket where it meets the transmission. Is there a way to find out whether its a rear main seal or not without removing the transmission?
Put car on ramps, add UV dye to the oil, remove any clutch inspection covers, then crank the engine and lay under the car with a UV flashlight, shine and watch the area as the engine warms up.

You'll be able to see if its rear main vs pan this way.

UV dye kits can typically be had for between $20-30 usd, and comes with dye, pen light, goggles and batteries for the light.
