Vargas has developed a solution to problematic PCV systems! Stock diaphragms on the gen-1 B58 Valve cover are fragile and can crack or tear over time. This can cause loss of crankcase vacuum and smoking. The VTT PCV cap replaces the factory plastic cap with a billet aluminum piece which uses a Billet Banjo fitting, and VTT's Vaccum/Boost adapter to move vacuum directly from the head ports to the manifold. This cap will also allow you to run a catch can on the low side if desired. VTT Recommends using this cap alongside their High Side Catch Can and crankcase breather for maximum efficiency. Installation is as simple as popping the stock cap off, removing the diaphragm, and placing the VTT components in place. Kit Includes: One Billet PCV Cap One Billet Banjo Fitting One Vaccum/Boost adapter One line with built-in check valve

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 secondary air injection pump injects fresh air into the exhaust stream to help burn off harmful pollutants in the catalytic converter. If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the lower secondary air pipe, you may see water pour out. This is a sign that your pump is more than likely faulty. By simply replacing this pump, efficiency can be restored and there will be no worry about failing an emissions test.
