Well spraying on a rock solid stock motor is risky, so its expecially risky if your spraying on a motor that needs a rebuild.

what is blow by?
and how do u fix it?

blowby happens when your rings are worn, cylinder walls are worn, rings arnt seated properly, ect. It is exactly what it sounds like, its when air/fuel mixture escapes past the piston on the compression/exhast stroke and when oil escapes past the piston the other direction on intake/power stroke.

Textbook definatition is: Blowby: The unburned fuel and and products of combustion that leak past the piston rings and into the crankcase during the last part of the combustion stroke.


Potentially you could literaly blow your motor into pieces if nitrous/fuel escape past the rings and into the crank case and ignite.
