Hey I am new here and to forums in general so bare with me but I have a question.
So I noticed my 93 180sx has a oil leak I am pretty sure its the valve over the rear moon parts of the valve cover (I ordered a new gasket just waiting one it) and the oil pan the lower one and when i was looking under the engine I found a line of coolant on my starter and I have no idea where its from.
Does anyone know where it could be form and or had this happen to them as well?
It doesn't look like a really bad leak, Not as bad as my oil leaks :/ but i would still like to know.

Thanks for reading

Go rent a pressure tester from autozone and put the system under pressure and see if you can spot any leaks/pressure drop.
