I posted this in the 911 engine build forum, and didn't get much feedback, maybe more can chime in on this side.
I need some input of the visual of the following valv/valve guides. I realize this is only a visual...............but a quick story of the car: I purchased it in July 2013 and the PO told me that his PO (Porsche mechanic) had overhauled the engine to some extent, but no paper trail to back it up (BTW, the car has 191k). The engine looks is very clean bottom and top. When I pulled the intake manifold to replace the fuel lines, I took a peak at the intake valves and notice that, in particular one valve was leaking oil, which appeared from the guide Now, the others also have some residue, but I believe the oil is from the over-filling the tank. The valves and guides do not appear as part of a 199k mile engine, but I could be wrong.
Calling all Pros: What are your professional opinions on this?
