I have a question about the Check Valve between the block and the battery. what does that thing do?
Right the check valve keeps the boost from the gas tank while allowing the gas vapors to be pulled from the evap canister. The checkvalve needs to remain and the line needs to be connnected to a vaccuum source above the throttle body on the intake manifold. If you don't pull the vapors from the canister the PCM will give you a check engine light with a probable code of P0442.04TurboSRT said::WTF: there is no such thing :lol: did you mean the checkvalve on the vacuum lines running below the battery tray? that's so boost does not enter your gas tank
