Hi guys, today i gave my car to a friend and i followed him with other car and when he reaches high rpm i could see that my car smokes a little bit, i think is oil cuz it was blue smoke, but its only in high rpm i think more that 5k. What you think guys could be the problem? Piston Rings? i performed last week a compression test and all the cylinders show aroun 185 - 190 psi so? someone could help me to decide what to change? thank you guys.

 

if it just smokes a little bit i wouldn't worry about it.

 

well its not a lot but you can see it from more than 6 cars even in the highway. And i think the engine dont have to burn any oil right?

 

please i really need help
