What are the requirements for a crankcase ventilation system?
This section of the Application and Installation Guide generally describes wide-ranging requirements and options for the Crankcase Ventilation System on Cat® engines listed on the front of this section. Additional engine systems, components and dynamics are addressed in other sections of this Application and Installation Guide.
How does the mini crankcase air breather kit work?
This kit provides an internally baffled housing which enables the fuel pump port on the engine block to be used to vent the crankcase. The kit also includes fasteners and gaskets to mount the fitting but does not include a hose fitting and hose. The fitting is tapped to accept a 3/8-18 NPT fitting.
What does positive crankcase ventilation ( PCV ) do?
Enter the Positive Crankcase Ventilation system! PCV is really simple. It simply means pulling the unwanted and unclean gases out of your crankcase using the engine’s vacuum pressure. This very same system is being used today. Because the 216/235/261 engines were the last to not have PCV from the factory, it is not hard to adapt them.
Where is the breather hose on a crankcase?
First, all crankcase ventilation systems need to address the operating characteristics of the installation. In-line drives are usually “nose up” and therefore, it should be common sense to find an area towards the forward high part of the engine (valve cover, timing cover) to attach a breather hose.
What do you need to know about crankcase ventilation systems?
Crankcase Ventilation Systems Application and Installation Guide © 2015 Caterpillar All rights reserved. Page 1 Crankcase Ventilation Systems Crankcase ventilation systems are designed to control the balance of air pressure between the engine crankcase and atmospheric pressure while processing the accompanying fumes.

What happens when crankcase air pressure is too high?
Crankcase air pressures that are excessively above or below atmospheric pressure can have negative affects on component life, the lubricating oil system and overall engine emissions. Ventilating the engine crankcase is not a difficult process in itself.
Which is the best engine for PCV installation?
The third and recommended candidate (right) is the Standard Motor Products V-237. Get the Standard Motor Products one so you do not have barbs on both ends of the Valve. You want it to sit in the grommet with no barbs on the engine side. If your Valve comes with a plastic barb on one side that has two outlets, large and small]
