2002 C4 Cab with Tip. 74k miles. Fun car, not a daily driver. IMS was replaced at 63k (LN Ceramic) and RMs/AOS done at the same time. Looks and runs fantastic... hoping for many more miles.

maybe he thought he was in the lowest mileage thread.

Check this one out - 500k Kilometres .... 300K + Miles

Owner delivers some parts for and works on old F1 cars - so knows a thing or 2 about cars

Yep 99's had double row and seem quite hardy...
The things this guy did are pretty amazing and he knows engines.
I thought this bit quite revealing...
A few things are different on my car to most 996, the engine has a lower temperature (72 degree C) thermostat fitted which opens sooner than the standard thermostat. The car also has no aircon hence my radiators are completely exposed to the ambient airflow down the rad ducts rather than being partially shielded by the aircon condensers, a second point on this is that the aircon condensers (when the aircon is on) heat the ambient airflow before it reaches the radiators which reduces the efficiency of the standard radiators when compared to them running with no aircon condensers fitted. Finally my fan on/off temps are set lower than a standard car, the fans go immediately to high speed when activated and constantly run at low speed below 60KPH to provide additional airflow to the rads at slow speeds.
One of the issues (for want of a better term) with the 996 is that it has a huge coolant capacity and therefore A LOT of thermal mass in the coolant, this means once it is hot it takes quite a bit of time to get this energy back out of the coolant and into the ambient atmosphere. If you can stop it getting that hot in the first place by increasing the cooling systems ability to shed heat to atmosphere you are in a much better position

"If that Turbo was in Los Angeles I'd be seriously looking at it and rubbing my check book."

This is how internet distortions begin
Deleted because above post mileage corrected :-)

The end of life of that 300+K Mile 996 motor

FYI Very long thread. That motor is apart now for a rebuild.
From what I understand, motor oil analysis of the basically stock/original motor revealed high copper content. A tear-down found worn camchain guide material had damaged a crank bearing.
The conclusion is that 996 camchain guides should be replaced at 250k Miles. It sounded like cylinder and valve wear was substantial as well. (the OP speaks a foreign language, British English
so the terminology is a little confusing. Feel free to clarify or correct me)
