Most important place to get the carbon out is inside the top ring groove. If carbon is left in the top groove and new rings are installed in the rebuild the carbon will not allow the rings to compress properly. There goes your high dollar rebuild because your piston's top land broke.
That was very satisfying to watch. Yes, please to more videos like this.
Great work,love the long videos but also these short ones are great too.More than happy to watch any car videos you make and often watch your old videos again and again while waiting for new ones. Hope you have the best Xmas you can in these crappy times😷🎅👍
Yes Aaron. Bit to be honest I’m missing the rs turbo’s. I love it when you do this sort of video. Your so methodical with your tinkering. Would be great to see some more vids like this on the blue ovals. Keep up the great work pal
Every time you upload a vid I stop everything and have to watch it.
These are great tip fillers in between your main projects uploads
Great stuff 👍🏻
Another decent video fella keep up the good work and we all wanna see more videos so what ever video is going im happy to watch looking forward to your next video fella 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Your knowledge, attention to detail and professionalism are on another level. Anyone lucky enough to have you work on their engine knows they are getting the real deal 👍👌
Enjoy your Xmas! Great upload as per usual
awsome! lots of great stuff in here. i'm cleaning pistons right now and i might sand them now. thanks.
👌🏼 very helpful content as always Aaron 👌🏼
Satisfying to watch. Love the Step By Step Process Please Do More videos Like This
Yes definitely love these kinda videos! Keep up good content mate love your videos
Great video Aaron, beautiful work 👍👌😃
love you channel very educational and love your work and passion on cars 😎👍
Great tips for people ripping apart their engines 👍, I would love a quick video on different z20 setups you like and dislike and the ultimate z20 engine. For example different cam setups, intake manifolds for different builds/budgets, favourite turbo setups for daily/fast road/track/racing.. etc... making 400 on a k04/k06 setup?
Keep up the good work tho👏 love the vauxhall videos best guy on RUclips for them 👍
Fantastic results! Very well explained. I may be doing this on my 1997 Land Cruiser restoration soon.
I imagine you are still waiting for the right weekend?
@@Wavezone304 For mine? I am remodeling the first floor of our house. Trying to get that done before getting back on the Land Cruiser. Tile floors, cabinets, paint, base board, bathroom, vanity, etc... Taking a lot longer than I anticipated. Gotta get it done first to keep the wife happy 🙂
very good video , feels like im learning loads even though i havent a notion. cool video for sure post more
Thank you, Thank you that was great to watch and yes more videos like this please 🙏🏻
Will do!
Another fantastic video pistols look lush all polished top job
Yessss, more content 😎 keep it coming
Wow amazing work, very informative. Thank you. 😄
Great stuff to watch again
Purple scotch bright is the best. I even put it on the buffer for cleaning up steel parts but use the cloth wheels and compound for the aluminium.
Great vid. Try soaking for a few mins in EGR/Intake cleaner for the first step Aaron. That stuff just melts away the carbon. Also good for freeing up the ring packs.
Carb cleaner too
Perfect job ! You are a perfectionist, it's so satisfying 😜
Can you show us the result after 10k miles utilisation ?
Im extremely happy when theres more videos from you regardless of the length type But i would appreciate a video on z20let engine auxiliary water pump which is not working after car is switched off. I have changed mine and when the car is switched off it dont work but does work when car is first turned on and runs until just above around 80degrees , then it wont come on again ,untill another cold start. So essentially not acting as an after run pump but more of a heater matrix resource. Any advice would be greatly appreciated too
Aaron please,please show us how to do the hard cut limiter so we can all be happy
Keep up the good work!!!
Satisfying and in real time most probably 1hr 30mins of work if not 2 hrs so effective 👌
This was super informative. Im taking on my very first rebuild at the moment, lots of questions along the way! I ordered some new wossner forged pistons for my build but they didnt come mirror polished? :/ I suppose i will just have to do it myself using the steps you have provided!
More videos the better Aaron love all your content short or long 😎👌👊
Great work as always your work is always second to none I have a question for you and haven't come across the info i need am basically in the middle of a z18xe to a z20let convershion on my mk4 convertible and I cannot figure out where the extra fuel return line connects to the tank and if it can on my 1.8 tank any help I would massively appreciate your help or any info on a video if possible many thanks
Looking good I'm having issue with my car were coolent is blowing out of cap so I'm ripping of the head and fixing the gasket plus send of the head to get tested but all in all I'm defo going to do this to my pistons on my z let
Wicked video mate. 👍
I just read an SAE paper on mirror polishing piston and combustion chamber. Results in more torque and hp and improved fuel mileage.
Did you use a similar technique to get the block face cleaned for the new gasket?
Great video by the way
Beautiful job Sir
Loved that! Also love autosol! I use that on everything 🤣
I did the same when I rebuilt my ktm engine polished the top of piston and velves and the outside of the engine so it looked as good as factory if not better
Keep em coming 💪👍
Great tips! Thanks...
And just as start rebuilding my abarth engine! :D
Another guastion, what you use for painting cylinder Block and body transmission, how you prepare them to painting?? 😉What the material you use?
More videos the better fella, awesome channel 👍
Would like to see a arden blue gsi at some point 😉
Currently looking for one 👀
Hi fella I was just wondering if you build engines for your own cars or for people who would pay for your work. I love your attention to detail and if I wanted my engine done I’d like you to do it. Plus I could watch my engine being built on your channel.
Regards,paul
Mr muscle oven cleaner works a treat at getting rid of that carbon build up on the top of the pistons 👍🏻
Out of interest if you had a car with bad piston rings do you just replace the rings or would the block need machining or something?
Is there any worry that fluid could seep past the rings into the oil?
Very satisfying
I’m cleaning carbon off of a Yanmar Diesel engine. I’ve tried Wd-40, carb cleaner, acetone using a toothbrush, and a brass brush. The results are not that good. Even using a carbon scraper in flat areas. Is diesel carbon harder to get off?
Do the video about your tools(interesting dynamometric wrench) what the brand you use, how long you use them, how you calibration them, May be tell what better buy, from dynamometric wrenches? 😉
Nice job, but did you also remove carbon on the side of the piston?
Could I use something like neverdull for a polish?
Bro just a quick one do you do work for people if so how do I contact you in regards have a zafira vxr needs stem seals doing
Do more video we love it
brilliant,
Is there much point in cleaning the tops of pistons?
I can't see it personally
What exactly have you used to clean?
What liquid are you using in that spray bottle
Bonjour, quelle est le nom du produt que tu utilises pour la calamine avec le vaporisateur et le scotch britch? tes pistons sont en fer ou en aluminium? merci pour ta reponse
After our chat on Instagram and now I have this forever haha !
Hope it helps you mate 😎
So what's the magic potion in the 1st bottle?
Ola. Acompanho seu canal e vejo esses motores com preparação turbo original de fábrica e muito legal. Se no caso eu fosse compra um kit turbo desse todo original teria a possibilidade de me mandar o motor europeu e o mesmo motor brasileiro sendo que ele não é turbo eu gostei muito porque e tudo bem montado de fábrica. Valeu.
Can you reuse the piston rings? I imagine the recommendation is to replaced the piston rings. This is just another step for my learning experience.
Nice
If only I had the balls to strip my focus st this far, il stick to laying bricks and leave the technical stuff to you Aaron 🤣
Ye I would like Aaron to forge build my engine he is very good at the rebuilds I'd trust him more then most large companies
Yes please!
you ever worked on a vtec engine mate :)
Any chance of a video on the fiesta or is that 1 dead now
Working on finding a shell
Have you done a video for the earth mod?
Yes i have recently
This will make yr car some times little bit hard to start up. For me its good condition.. but if yo do this,,, yup yr car run so smooth and responsif... Use iridium spark after polish yr piston... Polagize with my bad english😵💫
I found contact cleaner melts carbons build up really easy.
I'd like to see a zlet find it was into a cosa B or c and see some custom work 😁
Absolutely! Corsa B gsi 🙌🏻
@@AaronUnknownPerformance Yea that would be a cracking project and enough poke to upset the golf r boys
“A couple of passes”
🤣🤣
Or use berryman chemdip carbon cleaner. Just let it soak awhile.

His "brake cleaner" is acetone just FYI.
Brass Hand brush is "soft" enough not the damage or leave any marks on the piston top.
And it cleans very well. Hand. Not machine.
Is there anything to back up the "more horspower" claim or is it just a clickbait or an assumption? (P.S. i did a little bit of skipping when watching so forgive me if I missed something)
OF COURSE...You should remove the rings for this whole procedure. Probably wrist pin too. Then clean it. Then clean it again. A tooth brush works fine. Whatever method you use...CLEAN IT.
So Nice 💘💘💘💘💘💘
Gasoline alone will dissolve all that carbon very quickly. If you add a fuel injector cleaner with PEA (polyetheramine). The carbon dissolved in minutes simply agitating with a soft brass bristle brush.
That’s it. I just did all 6 heavily encrusted pistons from a 240z and it took less than 30 minutes.
Nice. Did you do a fully mirror finish polish like this? What kind of performance difference did you notice?
I like to see Rebuilding a turbo core instead of buying a whole new turbo rebuilding it....would be good
Shiny
You could have a shave in that Aaron 😎
where are you ??? they do not sell these in the USA... and i just use a wire wheel on the crown of the piston and have done many hundreds of them...
Do you rap in your free time by any chance?
after using a laser I'll never go back to cleaning like this
A lot
Satisfying to watch, yes. But is this going to get you somewhere? Probably not, this super slight carbon buildup on there will be back in no time and does not matter at all.
I tryed the "tranny fluid and acetone" trick.
Nah.
Regular carb cleaner is the best. Melts it
This is a good option fo cleaning, but have once more option cleaning-try buy medical preperation, the name is DIMEXID(only liquid), he cleaning without a big Mechanical effort, very, very easy, but he freezing when temp will be low 20C, more effective if he will be Hot, but you must use Rubber gloves and Premises must be have a good ventilation,because he smells very bad and Harmful...
But if you try to use DIMEXID, guaranted you, you will be surprise how thay can cleaning.I use them My self. 😉
Good luck!! 👍👍
U wouldn't even know they r used pistons,they clean up very well seeing they were black!!
Detergents cost $150 , and new piston cost $75 ... good job!
DO NOT POLISH THE TOP.
"the coating helps shield the rings from heat caused by improper burn of the fuel which creates hot spots."
I just watch with sound off
I think if you left them soaking in gas youd have a much easier time
First😁
Nearly
Stick the whole thing in a tub of Coca Cola 👍
And leave over night
Too shiny for piston
You know you just could have used gasoline
This guy6
is using gloves he has used multiple times.
