For those who dont know, i rolled my 2000 z28 about 1 month ago. I went to start it up in the garage again and when it starts and idles it wont smoke at all. When i rev it up a little bit it starts to puff out some blue smoke. I didnt think rolling it could cause it to blow a head gasket but im not sure. Any ideas on what it could be? Also, just incase it comes down to it, how much would it cost to have a shop do a basic rebuild of a ls1?

 

Blue smoke usually means oil.

 

bad rings it is normal for ls1 to smoke when free reving as long as it is not execive or doing it at idle also then u are ok. headgaskets are not blown.

 

i was thinking maybe some oil got stuck in one of the valves from the roll over. Some oil came out the filler neck when it was upside down so i think thats what happened. Im going to change fluids and let it run for an hour or so and try to burn whats in the valve out

 

i changed the oil and let the car run for about 20 minutes but it kept smoking. it calmed down a bit more but still smokes heavily when free reving. any suggestions on what could be the problem? I might have the car towed to a shop if the smoke doesnt go away by saturday.
