Does CRC GDI intake valve cleaner really work?
This product will indeed work, however in the process of expelling carbon from the intake valves the catalytic converter will get clogged and damaged. You’ll get an engine light with a P0421 error code in the computer. The only possible fix would be to replace the catalytic converter which is a very pricey repair.
How do you use a CRC intake valve cleaner?
Your assistant should rev the engine to keep it from stalling while spraying. Do not exceed 3,500 RPM. Have your helper keep the engine at 2,000 RPM, this is important so the engine does not stall. Spray CRC GDI IVD® Intake Valve & Turbo Cleaner directly into the throttle body in short bursts.
Can you use CRC intake valve cleaner on a diesel engine?
Answer: Absolutely DO NOT use CRC intake valve cleaner on any GDI vehicle. Especially on Ford EcoBoost or VW GDI engines.
How to use CRC GDI intake valve cleaner?
Have your helper keep the engine at 2,000 RPM, this is important so the engine does not stall. Spray CRC GDI IVD® Intake Valve & Turbo Cleaner directly into the throttle body in short bursts. Once the can is empty, rev the engine from idle to about 3,000 RPM (do not exceed 3,500!). Let the engine idle for 1 minute, and then the turn it off.
What’s the best way to clean an intake valve?
Then during the 10 minutes required to ‘rest’ I reassemble the intake, put tools away then take it for the ride to the shop. There’s a test somewhere where they used all the modern intake/valve cleaners on a GDI, and CRC was the clear winner. At least that’s how I remember it. .
Do you need to rebuild an intake valve?
Don’t worry too much, however, as this does not require rebuild. You just need to clean the inside of your engine with an intake valve cleaner. Unlike cleaners that you pour in your fuel tank, CRC GDI IVD® Intake Valve & Turbo Cleaner does not get diluted in the fuel.
Why is the intake valve cleaner in a direct injection engine?
This leads to uneven idle, poor acceleration, and lowered fuel economy. Direct-injected engines have an even higher rate of intake valve carbon buildup due to the fact that fuel never washes over the back of the valve to help clean the deposits. Carbon builds up much faster on GDI (Gasoline Direct Injection) engines.
