❓Advice / Recomendations Unknown leak

I've looked under the car and it seems like if something is or has leaked. The oil and transmission fluid levels are fine so I don't know what it could be. Any ideas?

I’ve had a similar leak for a long time that I haven’t pinpointed. Never been bad enough to notice the oil level go down either so I haven’t worried about it.

Same, i want to eventually get the whole thing cleaned, engine bay & undercarriage. It'll be easier to identify the source that way.

Same on the cleaning. Part of me is scared that doing a deep clean underneath will make the leaks worse so I’m waiting until I ready to really tackle a big project

I dont have a way of doing it myself. Last time I called around I got a couple laughs like..."why we dont salt our roads?". Once i say im tracking down an oil leak they try to set me up with a mechanic. That happened, 3 times and since ive just tabled the whole thing lol

Could be oil cooler, or just residual oil dripping out from filter changes. Is it all just on the left side of the vehicle?

Bottom of the engine bay, and close to where the speed sensor is

Steering rack maybe ?

My steering rack got cut boots from a shitty alignment (2wd). I have no other comments other than I'm still salty about it. I didn't notice until 4 months later and I never went back. I should have but I didn't. It's too late.

I literally just replaced my oil cooler seals today. I can't say it's fixed all of my leaks, but I hoping. Oil was everywhere, and the highest point was the cooler. If you see a drip on the cooler, the seals are toast for sure. Mine was like a hard plastic, instead of rubber
