Got engine stalled earlier today w/o any obvious reasons (no revving up, no braking - just started on green light and was turning right), followed by a cloud of white smoke and a smell of engine coolant (I think) while I was still in the car. In a couple of minutes I was able to start the engine and drive home w/o any anomalies over the next 5-10min. Visual inspection under the bonnet didn't reveal any obvious issues. How likely is that I got head gasket blown? Had brief engine overheating twice over the last 2 years, both times because of the coolant loss through a leaky radiator, hence suspecting head gasket damage dating back then.
No MIL light came on on this occasion although I recall occasional (rare) instances of rpm instability that I could never explain.
Assuming it's blown head gasket indeed will K-Seal help at all?
