Inlet manifold de-coke (2 Cars done)
- Thread starter simontown
- Start date
Thank you Jon for correcting me....I'm no technical expert....but the engine is definitely running better...more power....and less noise especially under load...guess that's when the noise increases on most engines. Given what we cleared out its obvious that performance will improve....bit like a lung transplant !Jon_G said:
Be interested to hear TypeR's experience....or any one else who takes the plunge....perhaps we should have a competition to see who can get the most gunk out of their manifold !
Thanks again for the feedback.

well i'm doing this on the weekend hopefully. Looking forward to it tbh. Just worried about these fuel rails and getting leaks after
Give yourself plenty of time believe me that junk took one hell of a lot of cleaning out!TypeR said:
Re the fuel pipes be careful not to over tighten them....if they don't seal first time take back off and try to reseat.
Make sure you take some pictures!

Don't worry too much about those high pressure pipes, just keep the ends clean and give joints a good wipe with clean kitchen roll as you reassemble them.
I'm interested in hearing about the economy improvements you might be getting.

For sure mate, plenty of pics. My car has 108k on it so thinking it will have some gunk in there.Simon1602 said:
Not too worried about of the fuel lines now after what you said. Any other tips?
Thanks for that Jon, like i said thats my only concern. Other than that I can strip it down.Jon_G said:
Well hoping to strip down on Saturday evening and then leave it overnight for a soak in some coke
Carefully scrape out as much as you can with a long screwdriverTypeR said:
Plenty of brushes....tooth brushes x 3, a cheap stiff wheel brush small and large if you can for ports
Latex gloves a plenty
Selection of cleaning agents....solvents and degreasers I used neat G101
Hose connected to a hot water supply....the hotter the better
I think if I did again I might try overnight soak in petrol rather than coke.....with perhaps a few hours in the coke before.
I used a large painters bucket to soak the manifold....make sure you have one big enough and also enough fluid to cover the manifold fully
Brake cleaner x 3 cans for swirl valve, sensor etc
Old microfibres as many as you have
Take care cleaning the ports on the engine side
Good luck buddy!
Thanks for the list dude. Not a had a chance today as my brother has had the car all day. Looking like it will be next week now unless I get time tomorrow.Simon1602 said:
Don't worry will definitely be doing this as i'm sure the Accord will benefit from it
What do you think to this for cleaning?

Nothing wrong with the Mr Muscle as far as I can see....soak over night in petrol, pressure or hose out....hot water....then see what you are left with....perhaps try oven cleaner next?
Not to keen on the extreme method though

So how has the Accord been since the clean?
Fast, smooth and quiet....very pleased with it...like a new car.....always wanted a sleeper and that's exactly what it is
Longer run tomorrow which will be more revealing.
Only trouble is it needs a clean on the outside now

[SIZE=10.5pt]So I had a bit of time today and decided to take this on. First up a snap shot of the engine as is:[/SIZE]

[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]One set of fuel lines removed:[/SIZE]

[SIZE=10.5pt]The cleaning begins:[/SIZE]
[SIZE=10.5pt]Scraped out with a screw driver[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]So to clean the actual inlet manifold I decided to use Mr muscle over cleaner:[/SIZE]

[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]Beginning to take effect[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]Throttle was quite dirty too:[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]Everything now just sitting there and the over cleaner taking its affect. I did this process 3 times and used my pressure washer to actually blast the dirt out[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]
[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]Ports now cleaned out, used a screw driver and a vacuum cleaner to ensure no bits fell through.[/SIZE]

[SIZE=10.5pt]Once all cleaned I used my air tools to dry off and then used a hair dryer to be safe. Once reassembled I was dreading the process of starting it.

[SIZE=10.5pt]Took the car on a long run and have noticed it does drive better and sounds nicer too. Hoping no air left in the system but overall really impressed with this job.

The Mr Muscle option was really good and only really took me about an hour to do. Not 100% clean but definitely better than what was there.

Good job buddy...interesting to see Mr Muscle finding a new use....anticipating a runTypeR said:
Just keep an eye on the fuel pipes I left the engine cover off and checked a few times...all seems well now so will refit.
Took mine on a run today and running well...no issues from the swirl valve which I did have..and good all round performance.
Yes think fuel lines ok, took it for an initial run and then checked all lines and all was fine.
Do see an improvement, car just feels smoother on the mways and pulls better. Held it in some gears to ensure the air has passed through the rail.
The bottom botls were a pain to get to, didnt realise there is a water line connected, just needed to push the bottom cooler down slighly to get to the bolts

Also i just moved my fuel rail to the side, didn't unhook. Did try to but it wasn't budging so just moved it softly.
Simon thank you for this writeup and hope more members use. Recommend everyone just adds to this
Edited the ***le also, will continue to do this each time a member does this

Shab excellent work!
Funnily enough we did my dads hyundai i20 last night.. didn't leave the garage till 530am!! But what a job.
We took out 5 years of inlet muck and blanked off the egr so it never happens again.
I didn't tell dad what we did.. He drove it today and said what the hell has happened to the car it's like a new car it's so fast
Shab bring it over one day I have new laser cut blanking plates now we can manually blank off the egr to guarantee this stays clean forever.

Thanks Fahad, it was a labor intensive job but well worth it.
Wow, 5.30am not had one of them for a long time. I totally agree it makes such a difference cleaning all the dirt out of the system. Bet your dad thought you'd super charged it or something
Definitely pop over some time and we can tinker with the Accord.
BTW picked the beemer up from Captain today, as ever an amazing job on the paintwork. Even had the fog lamps sanded/compounded and re lacquered, just makes the car look so much better.

Nice work fella!
It's cleaning the inlet ports that would worry me the most, as it must be tough to get out all the loose bits afterwards?

use a vaccum cleaner when cleaning them, it sucks all dirt out of the port.Jon_G said:
So whos the next member to take this on.
To give you an update, car has been fine and has been driving fine since. Have noticed better and smoother power delivery and pulls better at lower revs. Overall well worth it for me. Thinking about taking on my Sisters Civic diesel and doing this.

Sounds similar to me, especially the lower revs element....cruising on the motorway in 5th the pick up when you accelerate is significantly improved....
Next job new rear tyres, plus front headlights....can't believe how poor oem are....

After, say, 1500 miles or so I recommend taking off the engine cover and checking the high pressure injector pipework for signs of weeping... I had a look at mine in the week and I had a slight issue on one of the connections onto an injector. I pulled the connector up a tad tighter and wiped the fuel stain off, but I'll have to check it again in a month or so.
