Hi guys I have a question on Porsche factory rebuild engines
996 3,4 engine factory rebuild in 2010 (new ZF big IMSB)
The engine does not have the common M96 engine wine, I have a 98 Boxster with a 3,4 Carerra engine in and it has the wine, before that a 97 Boxster also had the wine, and the first 996 engine before replacing had the wine. (failed due to scored cylinder no 4)

As far as I know this is from the timing chains, but does any one know if did they upgraded the valve train on the factory rebuild motors. It runs much quiet and smoother. All run Valvoline high mileage 10W40 blend. No Mobil water it cost me a new engine.
