Blown Head Gasket Question

[ddmcse]

the rushing water sound can be just air pockets but it's usually the start of the BHG . the car will still kick ass at this point
are you getting a little spit up front ?
it's gonna run strong as ever until it gets more of a leak and then starts mis-firing you'll see and smell signs by then
at the water rushing point i think you are just passing gas once in a while into the cooling system . once you get enough you'll start pushing some out the over flow . the whole time all this is going on could be months. but once a leak starts water can sit right on the block each night and start corrosion of the block and head .
if you are going to use a metal gasket you need to remove the corrosion .
