Cleaning dirty Intake Valves with Liqui Moly Pro Line Throttle Valve Cleaner?

Рет қаралды 59,846

Күн бұрын

This video shows my experience with cleaning dirty intake valves using Liqui Moly Pro Line Throttle Valve Cleaner. Cleaning intake valves on direct injection or GDI cars is must if you value efficiency. This is my 2nd product trying to clean dirty intake valves on this 2017 Honda Accord with GDI. Intake valve cleaning remains a necessity to reduce carbon buildup in these engines.

@@DIYAutoworksNGdid you do the one hour heat soak after spraying it? On every other video they let it set and soak into the carbon for a hour before driving it at highway speeds? I guess that is what allows the cleaner to soak into the carbon?

Hey man, love your videos as always. I just wanted to comment that you might be seeing the other sides of the valve stem, as they are designed to rotate in operation, just my opinion, maybe it's not in this case. Happy new year.

I've used it 4 times so far and I've noticed some difference, engine was quieter and the car was more responsive. Surprised it didn't clean anything, but I'm looking forward for you to test more intake spray products like this.

In all honesty, car feels more responsive actually and it idles better. My fuel trims are now also close to 0!. Will test more😂

@@DIYAutoworksNGI've watched multiple people do this and the ones who have success are using crc but the main thing is the 1 hour heat soak. They spray it in then shut the car off and let it soak into the carbon for a full hour. Then they take it out and drive for 10 min at highway speeds.

Great video, but I believe CRC's intake valve and turbo cleaner does a superior job particularly on GDI's.

@DIYAutoworksNG 4 ай бұрын

Yep. CRC intake cleaner did a better job. I had to rewatch my video on that to verify. Yet to test it through throttle body injection. My prior experiences were through the brake booster line, but someone said it does better through the throttle body.

@TheScares80 2 ай бұрын

For the valve cleaner you did 5 rounds with the liquid moly in the tanks of petrol... one could draw the conclusion... that perhaps you need another few goes....AND try to clean them the way you tried with the other product (CRC - through the brake line booster?)

@DIYAutoworksNG 2 ай бұрын

Interesting take. I still have one can left which I intend to use too. The instructions don't say to use it any other way, but I'll do some more digging about that use through the brake booster line. Thanks for suggesting!

Is this the car you used the valve cleaner in the fuel where you aftet a few cans and italian tune ups , cleaned it up...this car is very dirty and would you say really needs way more help?.hiw many miles does this one have and what kind of gas was used..also id it only city driving.

Same car. Gas quality is not the best. Premium gas is not available. But then, it's GDI, so those are expected of the intake valves...

@don.timeless4993 Ай бұрын

great video! this product is good. product that cleans those areas in slow way is better for the engine so it dont harm the engine or the catalyst converter. so the solution to make it clean with time is to keep using the product regularly every oil change. these new engine with all environment systems need this product. also it's very recommended to use catalyst converter cleaner (add to fuel version) after using this product to clean catalyst converter from deposits came from engine components

Direct Injection was a stupid idea & there fix was to add more injector that sometimes spray over the values to keep them clean. Sure you get more power with direct but building engines for everyday cars with di is so dumb.

Believe me, I feel that frustration. That said, I won't totally call it dumb, I think car makers should do it the way Toyota does it; the dual injection way. Best of both worlds.
