ok to start it i was taking this girl out to a haunted place called the baby graves to give a scare so we were out there and we were leaving when this truck comes out of now where and gets be side me on a narrow gravel road and starts to get close to my car so i speed up to about 70 mph not a great choice but whatever then he swerves at me and i end up going into a field and i hit a rock put a hole in my rim so i pull onto the road and try to get it as far as i can and it over heats i was in 2nd gear 10 mph now i think my valves are out of adjustment and the thing is still overheating and blowing white smoke i think i might have blown a head gasket but the swap was done 1 1/2 months ago its a dohc zc i have no clue any help would be nice.

 

did u check to see if that rock that blew your tire didnt also put a hole in your radiator?
did you do a compression test?
