[EP5] Golf GTI MK5 Intake Valve Clean - Golf GTI Mk5 Build
HTML-код
- Опубликовано: 7 сен 2024
- In this episode I manually clean the intake valves by removing the inlet manifold and cleaning them with tools and a wire brush. The inlet manifold gasket injector seals are replaced as well.
Throughout this series I will carry out a variety of common mechanical repairs on this vehicle before a host of performance upgrades in preparation for some serious boost. As always my series will have no tragic humour, no fancy editing, and no advertising, just a strong focus on DIY work and building things on a strict budget in your own shed.

A few more tips with refitting the injectors:
1. The little white seal at 12:29 is impossible to get on with your fingers. The only way I could get it on was to soften it with a heat gun (or warm/hot water), lay it flat on the table, then push the injector down on to it. Even then it took a couple of attempts, the first attempt stretched it out a little, then managed to get it on on the second or third attempt.
2. The injectors are really snug and I couldn't push them in with my bare hands. So I pressed each of them in using a small flat metal plate resting against them so I could get more weight behind them.
3. The retainer at 13:28 was also tricky to push on. Once you've got it under the clips, you can use a 16mm deep socket on an extension to push it on evenly and around the injector.
Thanks again for all the help. Just finished the job today, and couldn't have done it without this video.
Great tips, we’re all here to learn. Glad it went well.
I did this myself. Thanks for the helpful vid. Its a def a diy, as long as you have the correct tools. Def get the injector replacement kit, because the original plastic things will brake. I changed the injectors too. A bit expensive, but worth it. I found the throttle body screws the hardest. The so called demon bolt is actually easy of you remove the dipstick and have a thin triple square 10 mm. Other than that, is not even that hard.
Edit: what helps is first scraping it off while still dry, vacuüm out, and then use the chemicals for the last bits.
You can remove the dipstick tube for more clearance by going under the car and hitting the lip of the dipstick tube up towards the sky. Make sure you have something flat when hitting it so that you don’t chip the plastic off and make sure you’re lightly tapping it until you hear it come loose. Hope this helps!
Thanks, was having trouble getting it off.
I suspected that was the case but was afraid to break it. Thanks for the tip.
So glad I got rid of mine! Between the 30 tubes and hoses and 5 different kinds of bolt heads.... could they have made this any more complicated?!
Superb tutorial, cheers mate, have to tackle this job on my edition 30. Thank you 🙏🏻
Another great how-to, keep ‘em coming!
For the Satan bolt you can get it off by jamming in a long 8mm round-head allen key.
The dipstick was the way for me and I wasn't sure how to remove it without breaking it, and it got in the the way off the triple square socket.
The allen key was thin enough to get between all the pipes, and the bolt isn't on terribly tight so if you jam it in hard enough it shouldn't round out the bolt (too much).
Add a box spanner to the other end of the allen key to give you some extra leverage when cracking it off.
Thanks for the great tutorial.
Thanks for the good input, I’ll have another one soon
I’m def going to perform this on my ‘06 tfsi. It should be running excellent after , since I already did the timing chain myself and everuthijg
Get your injectors flow tested while they’re out. Wishing I did so, one was a bit tired.
great series mate!!
what is a number of injector orings?
blast it
Were you not tempted to remove the swirl flaps?
Nope, they are there for a reason.
Is that a metal brush you used? Also how hard was placing the seal on those injectors?
Yeah metal brush, the o-ring isn’t hard. The little plastic seal is a bit of a pain.
Great video. Can you leave those flaps out.
Some people do, but they promote good air fuel mixture.
Can you make a video on that oil catch can
Yep got one coming
Where did you buy those seal kit?
VW Dealer
What do those plastic seats do for the injector,bcs i broke my today..?
Assist holding them, I think you will be ok without them. New version are metal.
@@cheapthrillsgarage i saw the new version,am planing to fit them without them,it would be good if it would work bcs i can't find those plastic peaces in my country
good work /and not so easy/ , the reason for carb is overused pcv -oil separator - you should replace it asap otherwise carb will appear on the intake, valves quickly
So did the oil catch can work, when was it installed?
Not really, so I went back to the factory PCV. It used a lot more oil as well because it’s not returned to the sump. The valve cover actually has a pretty good built in catchcan that returns the oil to the sump.
just manually cleaned my 3.5 ecoboost and im about to install catch can still researcjhing though
Why didnt you do swirl flap delete kit ?
They’re there for a reason
@cheapthrillsgarage yes of course. Can you tell me what problems you can get when these are removed thanks deano
@@deansteanson3481 They are there to promote better mixing of the air and fuel. Poor could lead to an improper burn, detonation etc etc I would think.
Hey mate I just brought a mk5 gti-v 2006. I brought it as a project car and was just wondering what you thought would be the best thing for me to do to it straight away as a preventative maintenance move cheers
My next video is going to be a 200,000Km service plus all the preventative maintenance items needed on the Mk5 GTI. Should release it by the end of the week hopefully.
@@cheapthrillsgarage awesome man, Been looking for an Aussie version of a mk5 project build and you just tick all the boxes, thanks man keep it up
@@cheapthrillsgarage how’s the vid coming along?
I have just acquired a Mk5 GTI, 08 plate, 120,000 miles, love the car so far 😎
Top things to do.... or check.
1. Cam follower for High pressure fuel pump - easy replacement.
2. Oil leaking from valve cover/ vacuum pump - another easy and cheap fix.
3. Thermostat temp check - common failure point.
I'm looking to do an intake clean myself as I dont want to afford the price a garage will charge.
No grease is needed
And no one should ever spray shit into this engines. Avoid that all at costs!!
Valves are closed
Valves are not closed at 17.16 when the engine is running. This does nothing for these engines. It's better to throw that shit in the bin than spray it into the intake manifold when the engine is running
@@bigeater1310 Spraying it in when the engine is running is just fine, the same as fuel being injected. It will assist cleaning out light oiling before it turns to carbon and sludge overtime. As I mentioned, you need to clean it properly like I did here to remove hard carbon.
