One additional thing that I do recall now is that last time I changed my oil back in november 2015 I used Mobil 1 0w40. Not my normal oil to go to. I usually use a 5w40 or 10w40. Not sure if this has anything to contribute to it. __________________ Todd Davis '95 Club Sport - Bosal Exhaust, Koni Shocks not installed yet-RDSport suspension,DASC Supercharger, B&M shifter '04 E46 M3 |'92 Porsche 911 C4 |'99 LR Disco II|'70 Volvo 1800E|'04 V70R Mechanical Design Engineer |
