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.

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 this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

An integral part of the emissions system, the PCV valve lets the crankcase breathe. This allows proper intake and exhaust flow, resulting in proper running and operation. When the crankcase vent valve fails it can cause excessive oil consumption, engine fault codes, and poor idle. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future.
