headgasket

Well the first time i had to resurface the head and brought paper head gasket, she worked fine for 3000 km, and then all of the sudden it blew, last time i changed it my self so i must've done something wrongor didn't tighten the head bolts, cuz sometimes the car turns off by it self, anywho...

So I got this car from my sister she’s not to mechanically inclined I had to do brakes all the good stuff well I noticed my coolant bubbles so I thought head gasket so I bought blue devil did what the instructions said burped the system all was good started right up no issues couple weeks later...
