My Alfa 155 (2.0 TwinSpark) hasn't been running on a daily basis because it's being stripped for a new paint job, so every time I started the engine (to let it run for a bit) and saw the white smoke and water droplets coming from the exhaust, I always thought it was condensation in the exhaust system.
The other day, I checked the oil level, and it was OK (oily colour, and in level), also the coolant was in level. But then for some strange reason, I took the oil filler cap and there was a tinny amount of white gunk in it (about 1mm tick). The engine starts perfectly and runs smoothly, and the temperature gauge always stays in the middle, even if I rev it a bit.
How serious can it be? My father-in-law is a mechanic, and he said it wasn't too serious, because is was such a tinny amount, but he is known for hatting Alfas, and working on Alfas
Could this be just an head gasket dying, or the beginnings of a cracked head? I don't mind if it's just an head gasket, because the engine was going to take one anyway (as part of a major service), but if it's a cracked head, It's a bit more complicated
