BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

The VTT B58/S58 Head Port Block-Off kit is designed to either seal off the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases, but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time. The Block-Off kit offered by VTT completely seals the factory head ports to prevent oil intrusion and unwanted vacuum leaks. This kit does NOT require any tapping, meaning no metal to get into the engine, etc. You simply tap the plugs into place. Key Features Eliminates oil draw-through into the intake manifold Prevents carbon buildup on intake valves Utilizes precision-machined plugs for boost sealing Fully reversible — Block-offs can be removed if needed No tapping is required. Easy install, by tapping the blocks into place.

The VTT B58 Head Port Check Valve Kit is designed to convert the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases, but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time. VTT's Billet Check Valve kit converts the head ports into a robust internal PCV system using precision-engineered check valves. These one-way valves allow vacuum to function as intended while blocking boost pressure from entering the crankcase or charge tract.
