So shes been sitting in the garage for like 2 days...i cranked her up this morning to move it out...as soon as i cranked it..for like 5 seconds i kept on hearing..a loud knocking noise and blue smoke came out of my exhaust..then it stopped...and the exhaust gas was an unusual smell...and then it stopped...when i rev it up..it doesnt feel as strong and rpms drop down slow..and a ****load of smoke comes out..my car is under warranty tho..
im thinking something with the valves, pistons maybe..anyone had this problem?

 

Model year of Z car?

Mileage of Z car?

 

sorry...2004.5...29k

 

Are you the original owner?

Blue smoke = oil

Any mods on the engine?

 

Bad fuel?

 

yeah i am the original owner..i thought about fuel
but i drove on this tank for over half the tank...oil has been changed 3k miles ago with the new 15k mile synthetic fluid..i change it every 4-5k miles

 

intake, exhaust, plenum spacer...

 

Agree. Tow the car to the shop. You have oil in the combustion chamber.

 

that is covered under warranty..im sure..shes goin 2 nissan 1st thing 2morrow
