AUTOOL Walnut Blaster, Engine Intake Valve Cleaner Machine, Automotive Engine Carbon Remover, Sand Blaster for Carbon Cleaning with 2kg Walnut Sand

I bought this machine to remove the carbon build up on the intake valves from a 2015 Mustang Ecoboost 2.3L engine. I watched a lot of videos trying to decide how I was going to clean the valves. I saw that there were less expensive options by buying pressure blasters, gravity feed blasters, cleaning the valves by manually scraping them with screw drivers or even using a bunch of tie straps on a drill. In the end, I chose this machine because it is all contained into one unit and the videos showed how well it cleans the valves. I am completely satisfied with this unit. It comes packaged well in heavy foam and it includes two bags of walnut shells and even has a nice pair of safety goggles. It took about 5 minutes to get it ready to use. I hooked it up to my air compressor (80 gallon 120 psi) and it took less than a minute of operation to clean a valve. The vacuum is strong and while there were some walnut pieces that were blown out into the engine compartment, but by and large the vacuum sucked them up and returned them to the unit to be used again. I realize that this unit costs more than what you might be able to build yourself, but I have to say that the convenience of just turning on a switch and going to work was well worth the money you might save by going cheaper. This machine cleaned all the carbon out of the ports and what was on the valves in no time. The vehicle runs great. Overall, 5 stars from me.

I have a direct injection Honda CRV. Like all owners of direct injection engines, I had excessive carbon build up around the intake valves that was causing drivability issues. This was the only consumer grade machine on the market that I could find. I was initially concerned that it would be a typical low quality Chinese tool. Boy was I wrong! It is a really well engineered tool built with quality materials. This could be used on a daily basis and I expect it would hold up well. It comes with everything needed to perform the job including walnut media. You do need an air compressor capable of supplying a steady stream of air. The vacuum is very high quality and it performs the job expertly. It’s basically a sand blaster (using walnut shells) that sucks out the media and collects it for use again making for a dustless operation. Since the included walnut media is collected and reused It would probably do 10 cars before needing replacement.There are several good YouTube videos on how to do the cleaning. After I did the initial cleaning I soaked each chamber in Berryman’s for a few hours and then repeated the process and had terrific results.One other observation… A lot of the build up around the valves is from the oil vapor introduced into the intake manifold from the pcv valve. I installed a catch can between the pcv valve and the intake hoping to reduce this in the future.

I have been looking at this item for many months and finally decided to purchase. It arrived from post office with outer box rough shape but inner package carton perfect. Opened to verify items and was surprised to find 2 small packs of the walnut shell material. I used it on a 2015 Chevy Malibu with 2.0L engine with idling issues cold. I could see from cylinder view with borescope heavy carbon on back side of intake valve. Took apart intake and blasted the valves clean. Only issue I had is since intake on rear side towards firewall, there is limited room. I solved somewhat by using tubing Bender on longer tube to make a 45 degree bend showing better cleaning down by valve. Really cleaned then up to like new for about 4 to 5 minutes each cylinder. Some had to do 2-3 times cleaning when I took tool out and still saw some carbon. If you are thinking about this item, this is definitely worth for shop use.

Ruined my engine. Couldn't vacuum all the cleaning materials out as a result it damaged my cylinder walls. Vacuum not strong enough

Have used it on several customer cars. Easy to use and works great!

Works great at cleaning carbon off valves. Makes them like new again. Easy machine to set up and use

I have no words for how cool this thing is! It is so awesome. All the guys in the shop love it! But you have to get the 18 attachments either sold separately online or buy the $600 one which is crazy. But with a little hose clamps and new fittings to fit your needs it is great! Great purchase!

Blaster included walnut media and two different length wand tubes. Found the shortest too long for my application on gen 1 3.5 ecoboost, easy fix, just cut one down. Yellow silicone adapters really aren't needed, found it was easier to insert the vacuum hose down in the intake port.
