I bought the car with 179K miles this year so I've only put a few thousand miles on it. It had the headgasket replaced 3 years ago, the radiator and thermastat replaced this year and the engine wiring harness will be replaced soon.

I don't really expect people to accurately esitmate when my engine will fail. It's just that I have seen M103s that have died or that have terrible oil consumption but every M104 that I have seen has been alive and kicking.
