Review on Allstar Crankcase Evacuation System - Weld-On, Universal Kit (Breathers, 🔧 Grommets, Check Valves, Nipples) - Requires 5/8 inch Hose - Steel by Jimmy Koroye

Revainrating 5 out of 5

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
