What are the signs of blown head gasket?

[Aaendewy]

I always wonder what the signs of the blown head gasket. I do know of a steamy black smokes but what else? For example, while driving on a blown gasket, what are the signs? any rattle? noises between shifting? lost of power?

Sorry I owned a turbo car not long ago, and I don't know too much about cars, any suggestion would help, cheers!

water goshing out of the top tank, milky oil under the oil filler cap, over heating is usually the first sign! hahaha!!!

get a compression test to be sure...

Sweet haha guessing my gasket is in perfect condition.. was shocked, boosting the other day, when my turbo about to kick in i heard a pop noise and my car decide to shut down on me.. I still don't know what it is :\ it cant be a blown turbo? because there's no white smokes? anyone have any ideas?

sounds like det or boost cut

did the car restart after the "pop" event?

if it did and running badly could be as simple as an air leak

have you got a front mount? aftermarket blow off valve?

this happened to my wagon and 2ks later my engine started knocking

Please explain more clearer, as the discriptiosns you are giving are too vague

Diagnostics over the net are difficult at the best of times

Prob best to see your local mechanic

black smoke is rich - not blowen headgasket - the pop to me sounds like fuel cut - too much boost or air leak - but from the description it could be alot of things

blowen headgasket as above - milk in the oil or under oil cap - water constantly being pushed out overflow bottle - overheating - white smoke (buring coolant) among other things
