My gsr runs good it started to smoke at maybe 5 rpm and up Idk y it doesn't over heat at all it is white smoke it isn't antifreeze Idk wat it is car doesn't lag it runsgood even when it smokes but it smoke a lot when u get on.it Wat could it be ? Piston rings ?

 

bump

 

Maybe a blown headgasket

 

wouldnt i over heat tho

 

Is the car consuming any oil or antifreeze? Take the spark plugs out and compare them to see if you see any physical difference in them. You can also buy 4 NGK spark plugs and put them in and compare them in a week. Open your oil cap with the car on and see if you have a lot of blow-by (a lot of blow-by would indicate worn out piston rings).

 

blow by as in smoke coming out or air

 

Both. Air will be during the compression stroke, Smoke during the explosion.
