    Cold air intake - bypass valve or not?

    I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e. g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one.

    Only version 1 of the AEM CAI's could even use the bypass valve. Version 2 will not work with this bypass. This bypass valve is pressure sensitive and set up to open if the air flow was blocked.

    Does ANYONE here know how to CLEAN intake valves?

    BMWs which have the fuel injector mounted in the intake port (ahead of the intake valve) often develop carbon deposits on the back side of the intake valves due to the fuel being, in effect, sprayed onto hot valves. The buil-up can affect the flow.

    To save a few pennies per gallon and to increase the competitive and/or profit margin of gasoline, some suppliers have cut back on the amount of detergent they add to their fuel or have switched to.

    Sticking Intake Valve?

    Model 28 B&S 12. 5 HP engine intake valve sticks. Please advise. When under a full load like tall grass, it runs great, but when the load is not as heavy, the intake valve sticks open, spewing gas back through the carb and mis-firing.

    Don't know anything about configuration of this model by number, but I can recommend you hit up your library for a copy of "How to Repair Briggs & Stratton Engines", by Paul Dempsey. I have 2nd.

    2001 Passat Broken Intake Valve $900?

    I am looking to buy a car and found a 2001 Passat online for $900. It has a broken intake valve and I was wondering how much it would cost to repair it.

    Don't buy it. Whoever gave the person the 900 dollar quote must not have any overhead. If it is just a broken intake valve. Which I seriously doubt. Intake valves don't just brake. The labor time.
