Stops oil consumption caused by missing check valve. The new external check valve is easily accessible for cleaning, and can be replaced for $5-15 Solves boost leak, loss of power, poor fuel economy, and oil consumption caused by missing OEM check valve Solves for loss of crankcase vacuum caused by stuck/clogged OEM check valve. Eliminates boost leak caused by aged, worn, or clogged OEM check valve by replacing it with a high quality, high heat resistant cone-style check valve utilizing an NBR seat. This kit use only high end components with Made In the USA brass fittings and a high end check valve made in Italy that resists chemical degradation, gumming, and blockage while also being easy to clean if needed. To date, not one person has needed to service their check valve after installing this kit. Extremely robust, overbuilt components that ensure many miles of trouble-free operation. This solution offers you the opportunity to cleanly retrofit a durable, leak-free external check valve that can be serviced easily and replaced for $5-15 should the check valve itself ever fail. The OEM intake manifold check valve serves this function well, while it works, but the check valve stops sealing well after a few thousand miles, producing an audible boost leak, sometimes disappears altogether, or gets stuck and no longer produces vacuum on the crankcase. You need to allow gas to freely flow from the PCV chamber into the intake chamber when the engine is under vacuum (not producing boost), but block that flow of gas when the engine is producing boost. You have two chambers the intake downstream of the throttle body, and the PCV chamber. Read the first post on the following thread, which explains how our PCV system works and will help you understand the solution better: It is your repsonsibility to ensure that the components are clean (such as the check valve and the brake booster tee fitting on the V2 kit) to ensure there are no potential issues. It is your responsibility to ensure that the components are working correctly and remain in good operating condition to prevent any issues. This is a kit that is being offered for your convenience. Neither I nor nor accept any liability for what happens during or after the installation of this kit. To ensure a proper install, MAKE SURE YOU READ AND UNDERSTAND EVERYTHING IN THIS POST. The PCV fix kits are cheaper, more durable, and more easily serviceable than any existing designs.ĭISCLAIMER: This solution has been tested, proven, and is generally considered reliable. The Dorman intake reportedly has the same flawed design. There is no redesigned part for this (at the time of this post's writing), and new intake manifolds are still failing regularly. Out of warranty, it can cost more than $350 to replace. The 1.4L Turbo engine (LUJ/LUV) in the Chevy Cruze/Sonic/Trax and Buick Encore has a check valve in the intake manifold that has a 100% failure rate.
These fix kits apply to the following vehicles with the GM 1.4L Turbo LUJ/LUV/A14NET engine: Read this entire page before purchasing a PCV Fix Kit!!!
