In my R19 TSE 1.4, I have an oil leak which appears to be just at the front of the cylinder head gasket. When the oil level is maximum on the dip stick, the oil leaks a fair bit when the engine gets hot (which I clean up BTW after the car has been parked for a while) BUT I notice now after driving about 100 miles, and basically cruising at around 60 mph. (amost without stopping), the oil level is half full AND the leak has almost stopped. Does this mean that it would be ok just to keep the oil level at half full (or maybe a fraction less) and in this way the oil would stop leaking? Apart from the leak, the oil level always stays very constant. My mechanic has told me that it would cost about 1,000 euros to repair the leak, so it's not really an option as the car is about 19 years old). Thanks
