Winter is coming
The C5Z is in hibernation until spring time. I don't have a heated garage, so working on the car in freezing temperatures is not an option. At least I can start to make a plan for the next season.
The car in front is an MB R350 with a stretched cam chain, lots of work to get that fixed on an OM642 engine.
Drivetrain maintenance
I returned from the last trackday with a load humming from the rear end of the C5Z, which is probably a differential failure. I'm hoping for a simple fix like broken belleville springs, draining the oil will give a telltale. There are already other issues that requires attention, so I guess the time has come to have it all sorted:
- Broken rear differential
- Engine rear oil seal leaks (which requires removing the torque tube anyhow)
- Worn slave cylinder ("clutch pedal stuck to the floor")
- Clutch and flywheel replacement
- Torque tube couplings and bearings
