Thanks bro you gave me a great idea, I have an engine that I pulled out of my car and removed the intake manifold, I'm in a desert region in Southern Arizona so there's light debris and maybe light surface rust from moisture, I stored it outside for 2 years and ready to put it back in but wasn't sure about the best way to clean the valves and valve ports, thank you for this helpful information

Thank you Alimech!

I ended up trying to clean carbon off the intake valves on my 74 MGB and had minimal success with any trick until I ended up trying a can of Liqui Moly valve clean. I soaked the valves overnight with the head at an angle and the next day it flaked off like it was dandruff. Liqui Moly valve clean is the best product I tried yet, and it works best in the gas tank. Use it occasionally and your valves and pistons will remain carbon free.

Great video, I have a Mazda 6 with exactly that fault it’s in garage now being fixed .

[edwardanthony]

Do that often enough the engine should last forever!

You know what's sad you are the only person on YouTube that I found so far that point out that engine degreaser's the best degreaser it's better than all that other stuff they're talking about and honestly I think if it let it silk long enough you don't need to brush it at all engine degreasers that good that drove strip the numbers off your microwave door

Excellent experimentation and presentation, thanks.

Cheap harbor freight walnut blasters along with my small air compressor works perfect every time. From tear down to back up and running again only takes me about 3 hours. Using walnuts to blast carbon creates perfectly clean, brand new looking valve stems and cylinder head. Plus you don't get the gunky mess you get with chemical cleaning.

I use oven degrease product to soap n clean all that gunk out from intake manifold, works great!!!

I need to do this on my mazdaspeed 3. But I don't have any of the tools but this looks like it works well. I'll give it a shot before I go and get a media blaster. And deff +1 on making sure the valves you're cleaning are TDC.

Excelente excelente hermano ésto lo tengo que hacer yo también. Te felicito.

Non-chlorinated brake cleaner is okay to get into the piston chamber. Most of it will evaporate and the rest will burn out. Should you clear a lot of carbon then pull the fuel pump fuse, pull the spark plugs and crank the motor. It will spit out the stuff in the piston. Do not use brake cleaner on vinyl or neoprene gaskets like on throttle body. Chlorinated brake cleaner can damage piston rings.

A sand blaster from HarborFreight is like 10 bucks, some fine walnut media is like 25 bucks also from HarborFreight so for 40 bucks you can do it the way professionals do it and it is so much faster when you do walnut blasting then using chemicals and a brush. To top it off in the long run it’s cheaper using walnut you can do probably 20 four cylinder engines with the one box of walnut, when using chemicals it’s way more expensive plus it takes longer. Also some chemicals can swell the valve seals which will cause the valve seals to start leaking, obviously the chemicals aren’t in direct contact with the valve seals but you are using compressed air and the chemicals are on the valve stem so some will work it’s way up the stem. Anyways if you clean the valves up nice all you need to do to keep them clean is use a cleaner every 15k miles or once a year you want a chemical that sprays a light mist through the intake over a good 30-45 minutes I have a pressurized fuel injection kit that runs off compressed air and I have an attachment that sprays a very fine mist it’s so fine it’s almost like a fog and it run it before the throttle body I run it at a lowest pressure I can to where it’s still a very nice mist so it lasts as long as possible usually 30 mins or more and if u use a quality chemical it will clean the carbon deposits off the intake valve and the intake runner, if u do this every 15k or every year after the valves are clean it will keep them clean so u don’t need to do pull the intake to clean the valves. You can actually buy a pressurized fuel injection cleaning kit that comes with the same mist attachment that I’m talking about for 50-100 bucks on eBay. The kit I have is much more expensive but I use it every day and I’m sure the cheap ebay kit will work just fine for someone to use at home. If u have direct injection buy one of the kits and keep ur valves clean before you have a problem.

Love from morocoo my friend ❤ merry Christmas.

Excellent, good work. I have a question: Has the engine been washed with water?

[Jayo-vqdm]

Thank you brother. Very informative and great video.

Really good job and amazing results. Unfortunately it's necessary for a most of new engines with direct fuel injection (gasoline). Sometimes it mandatory for diesel due to EGR works. Thanks for sharing your knowledge and I wish you all the best in New Year.
