I had recently(yesterday) put a ls stock motor in my integra (92) and I drove it not even 2 miles and temperature started to rise just over halfway then when it leaned more at 3/4th so i killed engine when I did I looked back while coasting and I have never saw so much white smoke in my life, then every since then, have been smoking white like unbeleivably bad, I think it is the head gasket....and other suggestions?

I have another LS head...
So if this was the case, I hear that the LS comes with a metal head gaskey unlike some other models that is re-usable?

Any help wont hurt....

 

sounds like you blew a head gasket or it was bad with the swap. if you got another head re-surface it to make sure it is level and do not re-use a head gasket less hassle for you cause you know you have a new one that won't have no sealing issues.

 

Blown head gasket. Check to see if your oil is milky.

 

plus 1 ^^^^^

 

Replace head gasket. Resurface head. When the head is off check the sleeves to make sure they are not cracked. While you are in there reaplce your water pump and thermostat.
