I just finished putting my valve cover gaskets on. I'm letting it warm up after putting it all back together and I notice the white smoke. It's cold outside and it's been doing this recently, but now it's smoking a little more than usual and it's doing it warm too. It smells like there's definitely antifreeze in there. Now my GOD D#%$ head gasket's blown too! AHHHHH! I really really don't want to be doing any more work myself right now and it's gonna be like at least 800 bucks at a shop. THIS SUCKS!
