Or feel anything is wrong with the engine? Misfiring? Excessive steam in the morning? Any CELs?
If he was getting excessive steam in the morning (and finding oil in the coolant reservoir), what would the cause be? just curious.
A blown head gasket can see coolant leak into the cylinders. This occurs very slowly initially and whilst the car is not running for longer periods such as overnight. During normal running the cylinder pressure doesn't allow the water to enter.
Therefore when you start up your car, water doesn't ignite, but is forced out into your exhaust where it evaporates due to heat causing excessive amounts of steam.
There's plenty of links and vids on the internet to provide more indepth answers and clips.
