I have searched through like 20 pages trying to get some info but haven't had any luck.. so i thought id make a post. I just replaced my Head gasket on my 94 gsr motor in a 93 hatch and didn't replace the head studs due to lack of funds. when we started it, it ran fine, when i drove the car it ran fine all up until i cracked vtec then all of a sudden my car starts spitting mass white smoke and eventually dies. i get it home and check the codes and now im throwin a code 21 along with the code 10 i was throwing previously and it starts up and runs fine until it starts smoking then it loses power and dies. i pulled the spark plugs and looked at them and it didn't seem like they had anything on them at all like coolant or anything. im about ready to just take this motor out and put in a stock ls if i cant fix the problem. could it just be the head studs? if so then why the code 21? any input would help alot thanks guys..
