Engine Blow-By Condition

For engines that are experiencing heavy blow-by AND you have enough vertical clearance above the #6 valve cover, then you can add an extension that will greatly mitigate the engine blow-by. Typical length of the valve cover extension is between 4″ – 8″.

Extension Kit Information

If you have chosen to add an extension kit to your EnviroVent product to better mitigate your engine’s blow-by condition, please enter the length in inches that you have available above the #6 valve cover.
