What was the mileage on the engine since you last attempted to clean the valves?

[@NATESINTERACTIVEAUTO]

I try to always thousands of miles between test

[@adrianniemiec8669]

How many miles on that engine at the time of this video ? I also have GDI and am a bit worried.

[@libertatusinperpetuum2046]

The proper way to do this on a GDI engine is to start your engine and drive it until it gets to operating temperature. Than add the fluid in short bursts AFTER the throttle body and MAF sensor. The brake booster line right on the intake manifold is the best spot. Keep your throttle at 2000-2500 RPM while spraying short bursts into the engine. Drain the can dry, this takes a few minutes as there is quite a lot in a can. Rev your engine a couple of times to pull the rest of the liquid into the intake manifold. Shut your engine off and wait one hour while the liquid soaks into the hot carbon deposits on the intake valves and intake port areas. After the 1 hour time limit, start the car and drive it out on the highway for at least 15 minutes giving it a good "Italian Tune-up" running it hard through the gears. Bear in mind that when you drive and rev that engine in this way, those valves are screaming and knocking all of the built up crap off of them. You wont BELIEVE how much crappy soot that will come blasting out of your exhaust(s)! DO this at every other oil change, I make that at 10,000 miles. I use CRC and not Amsoil and I and my Lexus intake valves and ports are very, very happy.

[@CookieManCookies]

Very nice, but I heard the stealership can do the same thing, and only charge $200!

[@transam8607]

I like to do it the way you explained it but use 1/3 of the bottle at a time like the first time you get most of the billed up second time you get deeper to brake up more of the stubborn billed up and third time to panitrat more i feel like that's the better way to do it but it's going to take a good portion of the day to get it done.

[@kevingrantonic8812]

If you have a direct injection engine with a turbo, can doing this process screw up the turbo?

[@cindysue5474]

@@kevingrantonic8812 No.

[@roachmotel69]

The problem with this method is it does not address the large carbon buildup in the intake runners and that's what affects performance the most. Once carbon buildup is past a certain point manual cleaning is the only solution. This can be labor intensive on some vehicles. Just a byproduct of direct injection.

[@TheRichardF10]

I think using E85 fuel would make a great video NIA. Regarding this amsoil additive, it did clean up the shaft of the valve a little bit.

[@stephanvanderheijden4953]

[@4O4FileNotFound]

If tiny holes were drilled into the plastic intake manifold right over each intake valve then the foam could be sprayed right on one valve at a time and might get a better result. Plug holes afterward.

[@97kt69]

[@chansaechao79]

[@bomason8595]

I would be concerned with hardened chunks of carbon being removed damaging the valve seating surface although the only other option is to remove the intake manifold assembly and walnut blast the intake ports and valve tops. My opinion for what it is worth. Remove the throttle body and clean it beforehand . That engine is extremely dirty.

[@xstorm_8_shadowx]

[@tompeter7326]

For me only solution is, take it apart, remove head, wire brush all parts, piston heads, all valves and intake runners, new seals and put it together again. Just another proof that all this "highly developped emission control systems" just go to far and do in the long run more bad than good. All emissions saved will be null and void after the necessary repair.

[@acvn-hg9gy]

Same for me, i lap my valves every 2 to 3 oil changes, and clean the entire head while also replacing gaskets. But not everyone is able to do that. This foam thing is just for les mechanicaly enclined people to give them some piece of mind; as we could see, it didn't do that much.

Can it be sprayed into the combustion valve through the car's bulges and then pulled out by means of an aspirator?

[@HiTechOilCo]

@NATES INTERACTIVE AUTO - Directly from the AMSOIL Product Data Sheet for the Power Foam; "Directions 1. Protect painted surfaces and mass airflow sensors (MAF) from spray. 2. Ensure application is in a well-ventilated area. 3. Run engine to normal operating temperature and remove air cleaner assembly. 4. While engine is running, spray Power Foam directly into throttle body as fast as possible without stalling engine. It is common to have to rev the engine above idle to facilitate this process. It is also common to see white smoke coming out of your exhaust. ---> 5. Once the sound of the engine improves, spray enough Power Foam to choke out the engine. Shut off engine and allow to sit for 10-15 minutes.

So I've watched 3 of your videos using different products on those filthy intake valves each product cleaned very little, I'm just wondering how each time yo've done this how can the engine valves look the same before using these cleaners. Something doesn't add up here. Logic would say before each cleaning the valves would progressively look cleaner and cleaner but they don't. Either your engine really pumps a lot of recirculated engine blow by to look amazingly filthy before each cleaning product. What gives?

Most intake manifolds are plastic now. Why not drill and tap a threaded hole in each runner as close to the intake valve as possible. Install thread in bolts into the tapped holes. Then when it’s time to clean the valves the intake plug(s) for each cylinder can be removed individually so that the valve can get hit by the concentrated spray directly. Then shut the engine down and spray soak each valve and let them heat soak for a bit and then install plugs and drive it like you stole it.
