Efficient vacuum removes accumulated crankcase gases.

I used a 90 degree heater hose which is perfect for my application. The chrome valve covers vented oil through the OD into the valve covers where they were crimped together at the bottom (crimping wasn't very tight) and I had to caulk them with some Ultimate Black, but this system works great. I installed a channel on each side.

Pros
  • Reduce crankcase pressure for optimal piston ring sealing, reduced oil leakage and increased engine performance
Cons
  • Not sure

Revainrating 5 out of 5

Overwhelmed (or probably sucked)

So only 3/8ths of the rod at 45Β° to the flow creates a vacuum at idle, TAAAAAAAAA with oil in the inlet causing detonation and spark plug fouling, 10/10! Venturi, just in case.

Pros
  • Elegant design
Cons
  • The list will be long.

Efficient vacuum removes accumulated crankcase gases.

I used a 90 degree heated hose which is perfect for my application. The chrome valve cover breather leaked oil to the valve covers through the OD where they were crimped together on the underside (crimping wasn't very tight) and I had to seal them with some Ultimate Black but this system works great. I installed a channel on each side.

Pros
  • Great for me
Cons
  • No instructions
