Who did the engine build?

Next to oil threads, coolant color comes up often. Coolant in oil is bad as we all know. Hoping Vern's issue is minor as others are too.
Unrelated perhaps, but why the green tinge?

To clear the air: A few people have mentioned this thread to me; asking if this engine was built by Flat 6 Innovations. NO, it was not.
I'll still try to help, though...
This does look a lot like condensation in the oil. That said, it would be considered a lot in my opinion. Either this engine is being driven on very short trips, or it has gone a long time between oil services.
It could also be intermix. Was the engine's heat exchanger replaced during the rebuild? I never trust heat exchangers, and replace them in every circumstance. Time in service doesn't do them any favors.
A used oil analysis is in order for this one. The percentage of water intrusion will shed light on this, and will identify condensation, or intermix clearly. If the engine oil shows water intrusion, but no glycol, then the water entered the system in some way other than from the cooling system.
Ironically Vern sent me a private message once upon a time after I stated that a "piece of paper won't protect an engine from failure". I was referring to warrantys, and how they are often falsely used to market and sell engines.

Use of good warranties to drive sales is a fairly common business strategy
I see these "image guys" all over the place in the Porsche industry. Their gimmicks make me sick to my stomach. Their false impressions are transparent to someone like me, but the average sucker out there falls for it. Just like flashy fishing lures, that catch fisherman, and not fish. I'll take 5 minutes to dig up some worms, and bring back a stringer full of fish, without buying a single lure anyday. That's just me.
Anyway, don't need to hi- jack this technical thread....
OP, are you using Brad Penn engine oil? That green hue in the condensate makes me think that you are.
What is your typical commute in drive time and miles? When was the oil changed last?
