Vacuum Check Valve – Black / White

Description

Mk1 Vacuum Check Valve

Upgrade your the EGR’s vacuum system with this Non Return Vacuum Check Valve for your Scirocco. This is the Genuine OES upgraded / superseded Porsche check valve. In conjunction with a new Power Brake Check Valve, it will improve and restore your vacuum system. These are used to keep the vacuum retained in the vacuum system until vacuum is needed. Even while the engine is off. Overtime these will wear out and stop holding pressure.

Diagnose a Your Check Valve

To check these valves, Check with a vacuum testing tool. If you are brave, simply suck tough each end. If pressure can be sucked though both sides, the valve is bad and needs replacement.

This is installs into the vacuum system and will control either the brake booster, HVAC or EVAP systems. If you have idle issues, this may also be faulty on your vehicle. Also check the vacuum connector hoses. Even if your line connectors look ‘ok’, they may still need replaced. Vacuum check the entire system, to determine if they are in fact leaking. We use a Mityvac MV8000 tool to test this.
