I’ve changed a lot of oil over the years but never seen this sticky oily smelling “sludge” I guess? Oil is not that old. Should I be worried? What causes it? The car doesn’t run hot. Good news is nothing metallic.

Never seen anything like that either. Do you know much about the history of the car? Did it sit for a long time? Could it be that this accumulated during a LONG slumber? Besides not being metallic, it also appears to be oil color instead of black like dirty oil that wasn't changed regularly.
You might consider draining oil, fill the crankcase with diesel fuel and let it sit for a while. Drain and repeat a couple of times. If its oil based the diesel will loosen up any that's left and flush it out. Afterwards put in oil, run the car for a little bit, then do another oil change to flush all of the diesel out. |
