Any ideas on what's leaking? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

It kind of looks like the oil pan gasket is leaking but I understand that that's rare for out cars. The oil pan is always coated with oil and theres always oil dripping from the drain plug. That may just be beause if it's the lowest point. I've replaced the drain plug with a Greddy one so it seems unlikely that a deformed plug was the cause.

Are you losing coolant? Those pictures look like there's a coolant leak from that heater hose.

Yeah, I agree.

The oil on the front crossmember is probably coming from a timing cover leak. Super common.

I am losing coolant very slowly. I changed the coolant a couple years ago so I'll probably just replace that hose when it's time to change it again.

Given that the fluid from the leak looks rusty, it might be a pinhole leak in the metal pipe.

Also, if the timing cover is leaking as @NoHaveMSG suggested, I've heard of folks getting a temporary fix by cleaning the area and applying a layer of RTV over the seam.

Why would the splash pattern face forward? I think this was a one-time incident.

Are you suggesting that he ran over a cow pie?

I'm suggesting that he may have backed over one.

I do not see a leak anywhere. The key to finding leaks is to clean everything and then monitor.
