996 Turbo engine question
#151
![Default](https://rennlist.com/forums/images/icons/icon1.gif)
To all,
My 2003 996 Turbo X50 just passed by 410,000 miles.
Last summer we dropped the engine - at that point it had a couple of minor oil leaks and one turbo's internal waste gate was broken. It was decided to rebuild the engine while it was out.
This car up until that point had and subsequent has used M1 0W-40 for better than 95% of the mileage. I had used Motul 8100 5W-40 for a few of the last oil changes prior to the rebuild. I am religious about changing the oil every 5,000 miles. Also it should be noted that my commute is about 15 minutes of 60 MPH to and from the home every day - nice warm up and nice cool down.
What we found when we got into the engine rebuild was virtually no wear on any of the internals - 2-3 of the bearings on the connecting rods had very light shadowing - VERY light. The rest of the internals were in remarkably great / perfect condition. My concern with the mileage was more of fatigue of the parts not of the condition - for that reason we rebuilt the engine.
This oil change history, what we saw when we opened the engine and the oil I used for those miles is why I am sold on M1 0W-40.
This is one data point - there are many others out there.
Good luck and drive the car already!!

Amazing T2. Thanks for sharing this encouraging story. You did not found any worn parts at the end of the camshaft for vario cam oil passage? Some of the rings in there got tendency to score the housing….

To all,
None of the parts we took out showed any excessive wear, anywhere. Call it luck, call it good cool down and warm ups. We were all amazed.
This car is a daily driver and sees 6-12 DE's per year, climate is typical four season weather and it is driven all year in all conditions.
The turbos and ECU are all stock as is the exhaust. The only mods the car has are Baileys DV's, I put protomotive intercoolers in about 2 years ago and the suspension is a KW Clubsport with GT-3 sways and adjustable drop links.

then based on your findings at tear down, my worry factor about the hot engine idle noisy rattle just flew out the window! Thanks much.

JG,
I actually replaced the front PCCB rotors and all four calipers about 18 months ago. Went with the current new part number for the fronts - it's now a 997 part. The rear rotors are still original.

Am l correct in thinking that you drove the car reasonably easy.
