1995 C280 Oil leak
 

Hi everyone. I have an oil leak that is traveling along the supply or return line from the transmission oil cooler (I think) on my 95 C280. I power washed the area and drove about ten miles and the only area I see fresh oil is on and around a rubber bushing and metal clamp that secures the line to the block. I actually have an identical leak on my 05' Nissan Titan so I am wondering if I am jumping the gun or is this a common line to fail?

Is it in fact ATF? Or engine oil? Need to start somewhere.

After further investigation am sure it has the head gasket leak. Its very minor but its def. the prob.
