I pulled into the Costco parking lot last night and could smell something funny. I couldn't swear it was from my truck so I sniffed around under the hood, in the wheel wells etc. and didn't find anything suspicious.
Tonight driving home (at a stop light) I thought I smelled it again but it was no where near as strong so I kissed it off. When I got home, I opened the hood and thought I could smell "that smell" ever so lightly and saw this oil mark on the turbo. Is this normal?
