VTT B58/S58 Head Port Block-Off / Built Check Valve Kit
The VTT B58/S58 Head Port Block-Off / Check Valve Kit is designed to either seal off or 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.
This kit provides two configuration options:
-
Block-Off Version – Completely seals the factory head ports to prevent oil intrusion and unwanted vacuum leaks.
-
Billet Check Valve Version – 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.
By bypassing the factory PCV valve in the valve cover, the VTT kit replaces it with an improved three-valve internal system integrated directly into the cylinder head. This design improves reliability, simplifies plumbing, and ensures consistent crankcase pressure management — critical for both stock and high-performance B58/S58 applications. This kit does NOT require any tapping, meaning no metal to get into the engine etc. You simply tap the plugs or check valves into place.
Key Features
-
Eliminates oil draw-through into the intake manifold
-
Prevents carbon buildup on intake valves
-
Converts to an internal, head-integrated PCV system
-
Utilizes precision-machined check valves for boost sealing
-
Fully reversible — Block-offs or valves can be removed if needed
- No tapping is required. Easy install, by tapping the blocks or valve into place.

Looking to up your boost limit on just about any BMW vehicle that runs a 3 or 4-wire BMW map sensor including but not limited to S58, B58, N54, N55, S55, S63, B48, B47, B42, B57, B46? We were too, so we decided to make a very easy plug-and-play kit for 3, and 4-wire BMW map sensors. These kits will allow you to completely replace the 3-wire sensor with one of our sensors, leave your stock 4-wire in place for IAT sensing, and move the power, ground, and sensor signal from the factory sensor to our sensor. These sensors have the proper scaling which will allow your tuner to simply change your map sensor scaling in the tune, and the factory ECU will be able to utilize the sensor voltage with no problem. We are offering these in 5 bar (58 psi), and 6 bar (72 psi), and each comes with a plug-and-play harness, and optional fittings for ease of installation.
Note: For the S58/B58 our Factory style Pre-Throttle map sensor is also 5 bar, and will work fine coupled with the post throttle kit, but the scaling is different, if you want matching Voltages Pre/Post throttle you can run two of these.
A variety of install pics can be found below and - Here

Unsure of the state of your CHRA's, whether brand new from a questionable source or rebuilt? Don't install them without having a proper High-Speed balance done! This is the #1 most critical factor when building a turbocharger, and is even more important for performance turbochargers or small twins that see a LOT of RPM. We use a Turbo Technics VS3 balancer, and balance most units down to under .5G Not all turbos will be able to pass a high-speed balancing test for any number of reasons (usually poor assembly, bent shaft, etc), if they will not pass, we will send you the specs they are in, and as close as we could get them. We then will give you the option to send them back, or we can disassemble, and rebuild them in-house using our other balancing, and assembly tools to ensure a properly built/balanced unit. The service is for most turbos, and we have the capability to balance most units, NOT ALL. If sending in twins please choose TWO as the quantity
UNITS MUST BE SENT IN WITH NO HOUSINGS, AND IN A CONDITION READY TO BE BALANCED, IF YOU NEED TO SEND IN COMPLETE TURBOS, WE CAN DISASSEMBLE, AND BALANCE FOR YOU, BUT AN EXTRA CHARGE WILL APPLY. IF THE UNITS ARE SENT IN A CONDITION WHERE THEY CAN NOT BE BALANCED WE WILL LET YOU KNOW THE PRICE TO GET THEM TO A STATE WHERE THEY CAN BE
