Since you already show the picture and obviously you already can tell how many work has to be done lmao

This is why I'm saying not working for gasoline direct injection since the injection are straight to chamber and is not typical people can do it when needed remove so many things haha

Any fuel cleaning additives add into fuel tank only work for port injector

Which mean the fuel spray into intake vavle clean the intake vavle and all the unburned things will burn at combustion chamber

Malaysia I don't see yet maybe have or I don't know but there are other way to clean direct injection by blasting similar wood Ash more hassle

This is why there are newly technology multi port injector when running eco using port when performance needed direct injection

the liquid added to fuel line won't be able to clean intake valve that much in GDI system but that's is where the spray will do it's magic.

if you know what you doing like to DIY ok lah when come to typical people which really hard for them , sent to foreman i guess rm30 labor charge no one want to do it , rm100? 150? 200? meh i don't know is this service include intake manifold gasket ? or just a silicone sealant etc , some intake manifold with water passage if typical people no idea what they doing block the water way GG then ....

if typical people no idea what they doing better sent to foreman , my logic no matter sea foam blah other liquid chemical agent when cleaning intake valve still need a proper experience like have to close the valve only you start cleaning which have to turn the crank pulley until the valve closed 1234 or 1432 no way allowed the big whole chunk just drop inside combustion chamber

still need air gun blow the remaining or clean up out of the intake valve any remaining cleaning agent residue etc , a lot good product out there still need proper way to proceed like the picture you show not a easy task

Seafoam for engine and tank works, for intake use Amsoil powerfoam,
Effect It’s most noticeable on older cars or cars that’s have neglected fuel RON rating and turbo cars leaking oil into manifold or NA cars leaking oil from breather or PCV valve. Good for yearly maintenance for throttle response and fuel consumption n smoothness fixing. Alternative take ur manifold and injectors apart and clean by hand 😂😂😂 😅😅😅😅

This is easier

DI need too do wallnut blasting or dissamble all clean by hand. Wall nut blast cheaper... n mechanic provide this service

haiyo, seafoam out of stocks....who go sapu all lah

park

i bought liao last year till now also not yet use lol.

Those old car need to be careful when use SeaFoam, as it's clean all the carbon in the valve might cause valve seal to leak...

the most practical way is to go above 140kmh or more on the highway when you go outstation. The longer you hold on to this speed the more carbon built-ups will be burned.

not only carbon, but also it cleans the injectors too.
it has got 2 product, one is clean intake, carbons, throttle body
the second liquid is poured into crankcase and fuel tank.
both cleans different parts

the liquid after pouring can immediately feel it, which i think my injectors are a bit dirty, now press a bit the car can move d.
so i'd recommend to use both.

actually liqui moly also have same range of stuff, one for air intake, one for crankcase, the other for fuel tank.
so it's already known that those 3 places need some chemicals to go in and clean them. revving alone cant clean fuel track and injectors system

There are these local made carbon cleaner (not sure but the packaging looks cheesy) that does the same thing like Seafoam but it is more expensive!

So anyway..where can get Seafoam? I don't think I saw it at Ace Hardware when I went there a month ago.

The liquid can be used to clean fuel line together with clean intake. I saw some ppl apply intake via hose after mass airflow sensor. So one can of seafoam can cover most of things.

Ace there sold out d I think. Hunt for it at 3 outlets only found one can.
I'll keep a few bottles next time when they're on sale

the liquid form is/was available in the melawati branch.

Is Vios 1st gen 2005 DI or FI?

if an old car (14 years) going through this method and might cause gasket and valve leakages, would it be wise to do it at the workshop and ask the guy to change gasket at the same time?

Better change cuz it's 14years old.

Or since it's leaking just do seafoam before sending over to mech

no leaking found yet, and I haven't start doing this treatment yet, i just found this thread this morning and still reading. Should I just do the oil change, run for awhile and see, if found leaking then only change the gasket?

Just to share...the other product with similar outcome is ThreeBond. There is no best, both Seaform and ThreeBond works pretty much the same. Individual preference.

Use liquid and spray.
Then go service.

If no leaking then just continue driving.
Just your car is very old, I'm afraid after removing gunk from engine might leak.

The one pour into engine is kinda like a engine flush
