Default Did I blow a head gasket?

Okay, white smoke only on passenger side. No coolent on the dipstick but the plugs on the passenger side do not look as good as the ones on the drivers side. I drove it around and it was only getting 12lbs of boost and falling off. It was also taking a lot longer to get into boost than normal. The car starts up fine and seems to run fine driving and with little boost but when you floor it it gets up into boost and then falls off.

I had thrown the belt a couple times last week and it got hot. Nothing crazy and I immediately pulled over, fixed the belt and when it cooled down fired it up and drove home.

Sound like head gasket?

Usually with blown head gasket the engine will overheat really quick.

Get a coolant pressure tester and put the system under pressure with the plugs out. See what happens.

Are you running a true dual exhaust?

When I blew my head gasket there was a huge cloud of white smoke when i pulled out of my work. My antifreeze was extremely low, however, there was no water on my dipstick, i drained the oil and there was no water in it. So i replaced it just to be safe, there was two small chips in the gasket on the driver side. Cool story, I know.
