What's wrong with my engine?
Hi guys,
I drive a hyundai i20 from 2010, 1.4 petrol engine (101 hp). There is foam on the cap of my motor oil. I have added a picture in the comments. Does anyone know what's wrong with my engine?
1.5 year ago I had coolant leaking inside my engine. The mechanic told me I had to get my head gasket replaced and the 'top part' had to get resurfaced. €3184,- later and my car was working again.
now 1.5 year later and I've only driven about 3500 km. My owners manual says I should get my motor-oil replaced every 20.000km or once every year. But since I have only driven 3500km I have not replaced the oil since the big repair. I can't imagine the head gasket to be leaking again, as it has already been replaced.
Thanks in advance!
