DIY Injector Cleaning In 60 Seconds! How To Test And Clean Fuel Injectors At Home  

No it's a Subaru. Move on to big boy rides ;)

@@dennismaddy5706 LOL what a silly comment. Not like Subarus have won countless races or endured some of the toughest competitions in the world or anything. I think you need some old-timer advice. If you don't have anything nice to say, better to not say anything at all. Wonder how many of your "big boy" rides would beat my Subaru down a dirt back road.

It's a swap right? I've never heard of a v10 impreza. either way turbos make everything better so I say as manny and as big as possible 😂

@@NomminOnRam3n haha, yes it is a completely custom swap by me! Thank you.

@@NomminOnRam3n Oh, and yes I already have two big turbos to go on the car!

Haha it's a cheeky self advertisement for my V10 Impreza build, but this applies to most injectors.

I was like HANG ON A SECOND! Nice car btw

I thought it was a sin to engine swap any subaru

Jack your name is a big like what moment

@@rustypotatos how

Hehehe 💪😤

Lmao I did I was like wtf is he talking about imprezas don't have v10s🤣

3 times and a pause

Literally any car person

I thought he put a Ford V10 in it 😅

Hahaha check out the TikTok for many vids of it running the full series will be on RU-vid coming soon.

@@802Garage Hey Man, cool video. Where abouts in the 802 are you at? I grew up in Franklin County.

@@markmalaney5224 NEK near Lyndonville!

@@802Garage Right on

Hahahaha yesss.

helpful. I was just about to use the non-flammable one

Wouldn’t it dry way before ever being able to ignite? Like while you’re finishing the next injector the others should dry off on their own and nothing really left to ignite?

@@michaelmichaelmotorcycle2174 You're running it through the injector there's a likelyhood of it sticking around inside the injector where it won't readily evaporate.

This would have been useful. I sprayed this into my fuel pump housing to clean all the gunk out. I used a blow gun to push air inside to dry it all out. You think I'm fine?

@@seahawksforever9504 If it's still off the vehicle I'd leave it sit to dry for several hours and maybe blow it out again after that just to be sure it all evaporated

😂😂😂 Holy crap that's a hell of a first comment.

Your wife must be one happy camper.

🤣🤣🤣🤣💀☠💀

did you back-flush first?

😂😂😂😂😂 Reminds me of a demostration test to see how far a man can ejeculate. Youd be astonished at the results 💀

Yeah I think I'm gonna take the rest of the injectors for this engine, clean them off, let them soak in some water based degreaser for a bit, the give them each a quick flush like this. Good luck!

I'm just stoked to hear the V10 Impreza is getting worked on at all!

@@wilsonoberholzer2771 Oh it definitely is. Getting pretty close to driving and the full build will still be going up here.

@@802Garage I just giggled like a little girl watching that video of it running

Hahaha thank you! Obviously you can modify the process to your needs or just build off of the ideas, but I just wanted to be helpful and give people a cheap way to clean a sticky or poor flowing injector. It worked very well for me!

Yeah I agree brake parts cleaner is not the ideal solvent, but it does work. I'm not sure I agree that carb cleaner has any lubricating properties, but it is probably a bit less harsh. Either way it worked!

Thanks a ton! I will have the full build series soon. Check out the pinned comment if you haven't.

Check out the pinned comment!

Yes, add a couple v10 stickers to your car and youll acheive your N4S desires.

Thanks! I'm sure there are better options than O'Reilly brake cleaner, but it's what I had on hand. 😂

Thank you very much! Means a lot especially since I tried to condense it into a short format.

Eyyy! Thanks a lot. Can't wait to actually put the series on RU-vid it has just been so much work to get here.

@@802Garage Trust me im sure that works gonna satisfy you and your viewers haha

Yuhhhhhh

I always appreciate some good reuse!

Haha thanks so much! There will be many more videos coming to the channel. For now check out the pinned comment!

Well that's what duty cycle is. Injectors can be held open when they are at 100% duty cycle. I have never seen any proof or evidence that holding an injector open will harm it. It's a simple solenoid it's either on or off. Seems to me turning it on and off hundreds of times per second with countless in rush and cut off current spikes would be much harder on it than simply holding it open anyways. It will only ever draw as much current as it needs to remain open. At any rate, not trying to be a jerk at all, I just hear this all the time yet I have never seen it substantiated in any way. I will probably do a video on it at some point just to test. I agree with you for sure on properly cleaning and flow testing. This is just a DIY at home method. :)

@@802Garage I've seen injectors melt and lock up at 100% duty cycle. The coil in that solenoid is TINY. I agree that you probably won't hurt it during the short duration of a cleaning, but I feel it's wise personally. I think driving an injector at it's duty cycle limit is probably worse than a continuous hold. I hear what you're saying about the rush current but at the same time, solenoids don't work properly outside of a specific rush current range, suggesting to me that they are designed for the abuse. Having said all of this, I'm not an electrical engineer lol

I'll probably do a testing video later. Find it very hard to believe a solenoid drawing a low current is going to melt itself even if you hold it open for a minute. A few seconds at a time certainly isn't going to kill it. If anyone can actually show me proof I am wrong, I will gladly admit it. So far no amount of comments or research on my part have shown evidence or proof of such. I'm not trying to be stubborn or anything BTW and I used to think exactly the same thing having read it multiple places. I just don't have any evidence to support the claim. Hence why I want to do some of my own testing sometime. I'm not an electrical engineer either, though I do know a thing or two. I suspect a bigger problem with holding injectors open may actually be with the injector drivers in an ECU, but I could be wrong.

Hahaha gotta love all the people in the comments who say this doesn't work who clearly do a lot more talking than doing. :) Works great. It's not a professional cleaning, but that's not the point.

Yep pretty similar! You can also buy an extra plug or get some better alligator clips and a momentary switch. :)

Hahaha it was a tight fit!

It likely has to do with cars which sit for long periods of time with ethanol in the fuel, yes. Almost all gas in the USA is up to 10% ethanol now, and while it causes no issues and has some benefits initially, when cars sit for a long time it can cause issues.

Yes. Your gas is much cleaner.

We don't actually have many clogged injectors. I've never seen one in my 50 years.

The environmental benefits are lies, it's actually terrible. I believe it also increases carbon build up - but that's just a thought I haven't read or confirmed it.@@802Garage

Haha very few comments so far! If you want to see the V10 running it's on TikTok and Instagram.

You're a legend. 🙌

Yes I do! Check out the pinned comment.

Bahahahaha I'm pretty confident yours will still do a better job! :D

@@802Garage I’m not so sure now. I think I got screwed😂😂

Thank you means a lot! The internet has a short memory, as we know. You were highlighting a pompous French streamer nobody cares about. Just address your mistake and carry on with your work. This nonsense will be over with quickly. :)

Great setup! Nice work.

Hahahahaha OMG that's facts.

I wish! I do want to make an H8 and H12 someday.

That would be so amazing to see

@@aamonsterbear989 I've long thought a twin turbo 5.0L H8 based on two STI engines stuck together in a BRZ to compete with something like a Mercedes AMG would just be insane.

I’m subbing, you sir are creative and I want to see more of your stuff

@@aamonsterbear989 Haha thank you very much! We did just rotary swap a BRZ and that series will be going up soon, then the V10 Impreza build.

Hahaha I generally love boxer engines, but I do get you!

Hehehe check out the pinned comment!

Yes I did. check out the pinned comment.

Thanks that was the goal hahaha.

🥺 Thank you so much. It means a lot. I am definitely going hard on Shorts right now, and I have gained quite a following on TikTok and I'm doing well on Instagram. However, I have a ton of long form content lined up for RU-vid as well, including the full V10 Impreza build series. It has just been a long road to sustain the business and get enough work done to really make an impact. I don't plan on stopping! :D

@@802Garage that's good to hear! I'm glad you haven't stopped especially on the V10 that was sick, I hope you don't stop making content it's always been a dream of mine as well and hopefully soon I'll get around to it but to see your channel go from I think like 90 subs at the time to like 30k+ is amazing in only a few years! Keep it up I believe as long as you don't stop no matter how hard it is youll never stop growing!

@@calumward1192 Don't have any plans to stop. Only make more. I really appreciate the support. Always happy to have an OG around!

Depends on condition. In general though, I agree. Luckily, I was able to reuse all 20 with no leaks. 😁

Oh and thank you very much! Big things coming.

Hahaha you're welcome.

We love to see it.

Check out the pinned comment too. :)

This is a heck of a lot cheaper if you just need to revive some injectors that have been sitting or clogged up. :D

@@802Garage great advice for someone who can't afford to just replace them.

@@antoniomartinez7993 Thank you!

Sure thing thanks for the comment!

I actually bought one awhile ago, still need to do a video on it haha.

Because I put it there. :D

@@802Garage love to see it

@@91CQM Haha thanks thanks. :D

Incorrect.

Hahaha check out the pinned comment!

Funny because I get comments saying "JUST REPLACE THEM!" and I'm just like... You gonna pay for 'em? Then everyone else saying "THIS ISN'T A PROFESSIONAL CLEANING!" and I'm like... Did you read the title? Haha. Thanks.

Cleaned 4 Yamaha injectors in my outboard 150 hp. It helped both times I took them out, and bench cleaned them, but rpms would drop after a few miles on the water. Bought 4 new Yamaha injectors( 600.00 , ouch) , back up to 5600 rpm, all day long. The old ones probably opened and closed billions of times. They do go bad.

I agree! Super fun. :D

Thanks so much! Merry Christmas and HNY to you too! I'm doing pretty well. I know I constantly say the same thing, but there really are big things coming to the channel soon. Thanks for everything. 😁

Nothing if you're careful. I literally did it to 10 injectors and never caught anything on fire. The one bit of advice I'll give is it's smarter to touch the connector to the battery side than the injector side.

Cool idea. They also sell fairly affordable testers. I'll probably make a video on one at some point.

Thanks fam! Hope you're well.

@@802Garage thanks man. All good here, how about you?

@@InitialDIYmods Winter was very rough, but I think it's gonna be a good year.

Yes, but the air doesn't have any cleaning solution to help break up deposits and gunk. It could help to pop a stuck injector though or you could fill a hose with solvent that clamps onto the Schrader valve with another at the other end to attach air and blow it through at a specified pressure. A lot of effort though.

Hahaha thank you so much! Check out the pinned comment and there is a ton more coming soon along with the rotary swap BRZ build. ;)

Def a great option!

Nope doesn't make a difference.

The quick answer is that if they are functioning properly and you have no leaks or issues, there is no reason to rebuild. That said, after 100-200K miles and especially if high quality fuel or fuel system cleaners aren't used much at all, the injectors could def use a cleaning. Mostly it will restore a proper spray pattern and more efficiently atomize the fuel, regaining some power and fuel economy. Fuel injectors are incredibly reliable though and as long as you drive the car regularly, they can last hundreds of thousands of miles. Running fuel system cleaners and some premium fuel a few times a year can go a long way.

Generally, I agree. Just was out, hahaha.

It's what I do hahaha. Full build series coming soon!

Great idea! I do actually have quite a few around because I used to work for a medical company. I use the big ones for brake bleeding. Makes it much easier with one person.

@@802Garage so find one that the plunger barrel is close to the injector oring you removed. You used the o ring for the seal on the syringe. The delivery end of the syringe can be modified to slip the red tube inside and use some double wall shrink tube to seal it. You can actually get a good little charge inside the syringe like this and quickly do many injectors. Cheers!

Thank you!

Hahaha there will be a full build series and in the mean time check out the pinned comment!

Yes I did! Check out the pinned comment. :D

Thank you!

Didn't seem to melt or dissolve to me, even the adhesive. It's a good point though. Best to keep the tape behind the tip of the straw.

I totally hear you people just gotta use their discretion I'm not OSHA. ;) I do try to show only safe methods, but in this case the worst some brake clean will do is make a tiny fire. Thanks for the comment!

Car, but you could possibly make either work, not sure.

Good info! Haha.

That's not how a solenoid works... If that was true then relays would all stick on, for example. You need to learn some electronics principles before you try to educate.

These definitely did. When I first started the engine only 6 or 7 out if 10 injectors were even firing and the 10th one never wole up until I manually cleaned it. It mostly happens from sitting long term, especially if the fuel system is exposed to air and there was ethanol fuel.

@802 Garage oh OK yea I periodically start my cars thier and here even if it's been sitting for a year or 2

@@ryuken7452 Yeah I do the same, but I bought this engine after it had been sitting in the corner of a shop for quite some time!

That is correct. Look at my Short about twin turbos and also check out my TikTok!

It should if they are a standard 12V injector.

Always a good choice. PEA cleaners apparently work even better.

Holy crap haha. Yeah it worked well for me! Injectors started our with a straight squirt or trickling and now make a nice mist.

@@802Garage mine were barely a mist the jeep wouldn't go over 30mph and for the life of me couldn't figure out what was going on and so I did this and it fixed it

@@TheCustomEverythingChannel Nice! I had rarely encountered dirty injectors in the past, but now I had this and I have an 04 WRX I've narrowed it down to the injectors. Hoping it works.

@@802Garage yea man well glad it worked out for ya

@@TheCustomEverythingChannel Thank you too!

If you use the closed captions you should be able to auto translate? If not, let me know and I'll add some official English subtitles which should allow it.

Good method for sure, just don't have one. This is more of a cheapest DIY. :)
