So I picked up my new to me 13 BRZ limited today with 59k on the clock. I didn't notice the burn oil smell after i test drove it, and I somehow missed the leak visually inspecting it. I've searched some and continuing to do so, but I'm in slight panic mode currently. Anyone have any advice on whether or not this is the timing chain cover leaking or the dipstick? I don't have a warranty, and bought from a private seller, clean carfax and the car has otherwise been well maintained. I haven't found much in the way of a DIY resealing the timing chain cover, am I missing a huge thread on this?
