My g40 engined, eatoned arosa has just found a new way to piss me off. After a rather long period of solving little problems here and there the car has now a new gremlin. The engine was rebuild about 9000km ago but just recently and after the last gremlin of climbing temperature was seemingly resolved tonight after pushing it hard for around 5 to 6 km the oil light started flashing. Reduced my engine revs, flashed 3 times and it went away! In the meanwhile the water temperature raised to about 100 and dropped to normal after some rolling distance. Note that the ambient temperature here is around 20oC, and I am using eneos 10w40 fully synthetic oil in the engine. Any suggestions cause I was getting ready for bigger injectors and a custom map and this may not be healthy with a red flashing light on my dash.
