Sea Foam Motor Treatment and Sea Foam Spray will clean different parts of the engine. Sea Foam Motor Treatment will clean areas where the fuel flows (fuel injectors), while Sea Foam Spray through the air intake will clean and lubricate intake valves and chamber deposits where fuel can't reach.
Sea Foam Spray is used by inserting the included application hose and patented hook tool into the air intake just in front of the throttle plates in the throttle body. Then start engine and let it warm up to operating temperature. Increase idle speed to 2000 RPM and spray the contents of the container into the engine.
Make sure the valves are closed. Spray and fill up the intake port with cleaner. Let it soak for a while. Attack the valves with picks or use a bundle of zip tiles. vacuum out the gunk and repeat if necessary. It's not a fast process but you don't need any special equipment.
No. 'Seafoam' or any other chemical additive won't repair mechanical damage or wear. A burned valve has lost metal from its sealing surface.
Spray continuously until contents are empty (approx. 7 minutes), then shut off the engine and remove intake boot to recover Hook Guide and Tube.
I use sea foam and it works. Meh, believe what you want, but I've done my own testing with this stuff and it does work to a point. I scoped the cylinders in a 2000 Honda Accord I had, the Pistons were black with carbon, after running seafoam through it they were definitely cleaner.
Issues with intake valves can lead to poor combustion, compromising the proper operation of the vehicle over time and reducing its performance. The indicators of valve issues include noise (ticking), loss of power, any ignition difficulties, high fuel consumption, and excessive smoke from the exhaust.
A Better Way to Clean GDI Intake Valves
Cleaning is needed every 10,000 miles or at every oil change to prevent deposit buildup. An error occurred. Try watching this video on www.youtube.com, or enable JavaScript if it is disabled in your browser.
One of Sea Foam's negative effects, per AutoCareAids, is that it can dilute the oil in your vehicle. It's possible, especially if you don't use the correct amount of Sea Foam, to thin out the motor oil, which seems to be one of the most common complaints by Sea Foam users.
We do not recommend running Sea Foam Motor Treatment through a vacuum line due to the risk of hydrolocking the engine. Instead, use Sea Foam Spray through the air intake. It's easier, safer, and it disburses evenly to all cylinders.
With the engine running, insert Sea Foam Spray tube (cut to shorten if needed) into intake throat (if carburetor) or directly before throttle plate opening (if fuel injection). Spray a series of 3 to 5 bursts, then a final direct stream while shutting off engine.
Sea Foam Motor Treatment works well to clean fuel injectors. The idea is to add a small amount of fuel (2-4 gallons) and a whole 16 oz can of Sea Foam Motor Treatment. Then, drive until it's almost empty to give the Sea Foam a chance to clean.
Gumout® All-In-One® Complete Fuel System Cleaner uses P.E.A. (polyetheramine) to effectively remove carbon deposits other products can't for improved performance across the fuel system.
Locate the entry point of the intake manifold and remove any components obstructing access to it. Spray Intake Valve Cleaner: With access to the intake manifold, use the intake valve cleaner spray to apply a generous amount to the intake. This cleaner is formulated to dissolve carbon deposits on the valves.
Carbon deposits and buildup are a by-product of combustion in an engine that comes from incomplete fuel combustion. This black soot, similar to that which collects in a chimney, will harden on internal engine components such as injector nozzles, cylinder walls, intake valves, and more.
Apply Sea Foam Spray through fuel injection throttle bodies to clean harmful engine deposits from intake valves and combustion chamber areas. Use Sea Foam Spray to fog engines and coat spark plug cavities to protect your engine during storage.
Yes, adding Sea Foam through the spark plug hole and soaking it will help to clean things up. I recommend using Sea Foam Spray (which is simply the aerosol version of Sea Foam) through the spark plug hole and letting it sit for 10-12 hours.
Use Sea Foam® Spray to clean carbon deposits from the intake systems, intake valves, and combustion chambers of your engine. Use Sea Foam® Spray to clean all of these areas with the cleaning tube inserted into the sealed air intake system. Spray Sea Foam® Spray into the engine from the front of the throttle plate.
