Default Oil leak


So I bought a 03 Z. Have been noticing little oil droplets on the garage floor after it’s driven. I have changed the oil filter O ring, oil pan gasket, and the valve cover gaskets and the covers themselves. Just been trying to replace parts that it could be. Only options I can think of now are the rear main seal, the crank seal, or maybe it’s the damn oil pan plug idk. Have noticed my oil pan has light oil on it. In the pic there is oil on that too. I’m lost lol

Clean first then identify where the oil is falling from by the location of the oil on the floor. Then look at where oil is dripping from the engine and then trace where it is running from the engine, that can be from two different places ie oil may be coming from higher up the engine and then running down to drip from a different part of the engine. Works for me.

I cleaned the area and am doing just that. Thinking about doing the UV test here soon

That's the A/C compressor right? So driver's side of the engine? Make sure your oil dipstick is fully inserted, it sits behind and above the compressor. Also make sure the dipstick rubber gasket/seal material is still intact. It's not uncommon for oil to spit out of there if the dipstick isn't properly seated.

I’ve seen it coming out of few areas of the timing chain case. Might wanna look at that? Lack of silicone? Bolts not tight?
