Head gasket or engine swamp?

[Axel parker]

Good morning everyone. Last year I brought a 2012 Honda Civic Si I love it. At the moment it’s throwing white smoke with a bit of bluish tint which white smoke mostly means head gasket there is no codes just my o2 sensor which always had it I even replaced it. But what would be better to replace the engine itself or am I still on ok zone or no🥹I’m worried that I haven’t driven the car at all since I also found a bit a oil on the manifold so that’s kinda alarming to me.

Do a full pressure test and see. No reason to replace engine if everything else is fine.

If it really is a blown head gasket that's like $1500 on the high side to fix. A "new" engine will be thousands more even if you mean a used engine.

Start with a leakdown test.
