what are the signs of a blown head gasket??? and i think i have stretched head bolts how can i find out both???

 

muffler throws white thick smoke.check oil cap and dip stick for a milky substance.make sure dont re-use head bolts buy a new one or better to use arp head studs...i got the same problem a couple of days.i fixed it today.took me like 2 hours to replace it.its easy to replace a headgasket so its better to replace it asap if ur sure that u have a blown hg...
