Brown liquid from intake?
Hello guys, I finally started my 2jzgte engine on my car to see if it's good, it ran great except that, after a little while, I saw brown liquid (like oil/coolant mix. Coming out of the intake tube that connect from the turbos to the intercooler. The engine only has oil in it right now so I'm kind of confused lol, though I've been informed that people tempt to power wash this engines before we buy them... I would like to know, is this a serious issue?
