Walnut Blaster Kit for Carbon Cleaning, 1200W Engine Intake Valve Cleaner Machine, Automotive Engine Carbon Remover with 2kg Walnut Sand, Sand Blaster for Carbon Cleaning HTS558

purchased to clean the carbon build up off the intake valves on my 2015 F-150 3.5 ecoboost King Ranch. She has 164K on the ODO. Mind you I have cared for this truck meticulously, Oil Change She ran fine but started to feel "Kinda Sluggish" . So I cleaned all my sensors, replaced the Plugs and cleaned the throttle body. All of that helped a little but did not feel like it was actually fixed. None of that hurt it, but still did not seem right. Also I had lost fuel mileage. On the highway I was only getting 17.5 and I knew I used to get way better then that. After searching, found intake carbon build up is a real thing on all direct fuel injection style engines.So I then bought a 30 dollar endoscope with a light that works on my android phone, I used the Manifold Absolute Pressure (MAP) sensor hole in the top a the intake manifold and went through there to look at the back of my intake valves. To my horror there were big chunks and the stems on those valves were caked. . It could use all that but obviously the carbon build up I thought had to be the real culprit. I even called around to different shops, a Ford dealer service manager actually said "We offer a chemical clean treatment, for 180 dollars. I have never heard of walnut blasting" I hung up, on a direct injection engine just trying to shoot a cleaned through the throttle body is not going to do the job, may make things much much worse if all it does is loosen chunks of carbon. We live in a pretty good sized city in the Midwest and aside from a couple Foreign car specialty shops that did not want to do my Ford I found no one.I'm 66 and in no way in great physical shape, not bad but not a fitness freak, I only say this to let you know while yes this took me a while, it was not that physically hard to do. Way more time consuming then difficult. Hardest part is just getting up on top the engine in a way you can gain access and work comfortably.This machine worked flawlessly, seemed well built and I was surprised at the vacume strength of this. Just need to be very careful the valves your working on are closed, and the ones your not working on are taped of, these walnut shells go kinda everywhere even though most get sucked back up. You DO NEED AN AIR COMPRESSOR!! for this machine to work. I have a 150 psi 30 gallon craftsman, older one worked perfect.Took my time, but once done the back a the valves looked new. Then used a shop vac and a tube on the end to go in each hole with the endoscope and clean out as many left over shells as possible, even pulled the plugs to check the inside of the cylinders themselves. Were a few in some of the cylinders so I used the tube and vac to get those out. Sorry this so long. But re assembled, started very rough stalled , I restarted and it ran for 20 minutes all the time it was smoothing out. Walnut shells are hard enough to clean but soft enough to not hurt metal, also will not harm cylinder walls if a few are left and they just burn up. Test ran, Truck feels new, Disconnected battery for all this so PCM would relearn, Highway mileage was at 22.5 MPG. I'm beyond happy!

Works amazing. I’ve done a few valve cleaning job with this

Works great got most of the carbon off with minor help from a pick tool

A large 60 gallon air tank would make this thing work better than just my little 30 gallon one just can't keep up. Works great highly recommend.

I bought this machine to remove the carbon build up on the intake valves. 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. 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.

Muy bueno muy practico
