so this is a video about cleaning EGR valves in particular the 1.6HDi engine
do you need to dismantle it in order to clean it and use carb cleaner
something like this you have to scrub it pour carb cleaner scrub it and then put it back together
but can you actually use these egr cleaners that you can buy anywhere i'm not affiliated with with
any of these i just bought it with my own money and you just spray it in the intake and cleans
your egr valve but how good is this i'll have a pre and after how it has cleaned it so it's
uh it shows a picture of quite dirty EGR valve and then after quite clean EGR valve and it says that
cleans the air intake system air flow sensor inlet valves and and egr system if you want
to see that stay tuned so this is my 1.6HDi Peugeot Partner, 2007 roughly about 106 000 miles
and i have a video that you can view here cleaning the EGR valve manually which is the best method
but you always see these videos where somebody sprays into the intake system and and claims
that it has cleaned the egr valve and i agree that would be really quick and easy way to do
if if that's possible i i don't know haven't seen a video of the egr valve before uh spraying this
into the engine and and after so this is a video taking the egr valve off showing how dirty it is
before spraying then putting it back on spraying this EGR diesel egr cleaner and taking it off again
and see how dirty it is or how much it has cleaned it as compared to manual cleaning i mean i suspect
the manual cleaning always be better but if this does well to some extent that that would be all
right to spray it from time to time so i'm not really gonna this is a 1.6 HDi engine i have
an oil catch can if you want to see the video here how i've installed it so I'll remove those so
yours will be slightly different there will be a black hole here or for the tdci engines will
will go along there so I'll dismantle those, this will be on speed mode to take out the egr valve
and then show you how clogged it is and then is the procedure of spraying in putting it
back on see how how clean this is so first of all is to remove all these components enjoy
so here is the EGR valve out um it's fairly clean there is a bit of a carbon around here but
otherwise it's fairly clean I'll have my torch so you can kind of see it hopefully
that's visible on the camera there is a bit of a carbon um that is um kind of fine dust everywhere
has covered it pretty uniformly i mean hopefully you can kind of see the valve down there it's not
too covered i try not to shake it so you you would see how there is quite a bit of a carbon uh here
and there but it's not really too badly clogged so I'll open the top to see how how is is there inside
so let's see how it's inside may need a bit of a shaking to get opened
yeah there is a let's first see this
yeah there is a bit of a carbon quite a bit of carbon here and there
it's like a powder i mean i'm not too sure you can see there is a bit of a
powder uh kind of everywhere around here some flakes that are bigger but let's
let me that is how it looks uh like that inside
also that part let's have a look at this quite carbonated throughout it's a lot of carbon in here
so I'll leave it like that not to disturb it put it back together and put it on the engine
well that's it i put the EGR valve back together everything put together apart from air intake
pipes from there to to to the bottom of the engine so it will suck a bit of a air from the warmer side
of the engine but but that's fine next thing is to get the engine pretty warm i'll have a 40 minute
drive and then I'll take off the air filter and start spraying with the with the EGR valve cleaner so i
got the engine pretty hot roughly about 30 40 minutes driving city driving plus some motorway
so it is pretty hot uh what it says on the egr cleaner on the description is to get the engine
to uh operating temperature remove air filter from the air intake system let engine run idle then
when engine is operating temperatures spray the product into the air intake manifold spray with
short intervals less than maximum one second and then the rpms will increase due to the air
ratio then let the engine idle for five minutes stop the engine reconnect everything of course
stun the engine drive to 10 to 15 kilometers do not exceed 3000 rpm and that's it first
taking the air box out disconnect the maf sensor and run it and start spraying
so I switched it off let it tick over for five minutes now is to put back air filter and go
for for a short drive roughly about five ten kilometers i think it's on the on the wynns
bottle 5 to 10 kilometers but do not exceed 3000 rpm there is a bit you can probably hear
it it's just on the bottom there's just enough not enough air to push it so next the air filter box
so i drove roughly about 5 miles or approximately eight kilometers
and no i didn't give it uh too much rpms maximum was 2200 rpm that was my maximum
drove it around for half an hour it has stood overnight at home so now to take the air filter
and egr valve and let's see if the wynns diesel egr cleaner has cleaned the egr valve
so EGR valve is out of the car so let's see how this looks like
hopefully i can have the same shots as before
it has literally done nothing as far as i can see it is literally nothing let's see that side
yeah that's i had a bit of a crud carbon on this side and still there and it's pretty
much the same um fine carbon everywhere next thing is undo that one see what what's inside
let's see how is this inside
let's see first here
i mean the same the same particles the same carbon is up there he hasn't really cleaned anything
and this
this is also the same carbonated it hasn't really cleaned
uh anything on that side as well what is next left is to do this manually
clean it carb cleaner and see how good it looks after cleaning it manually
and here the results with just 10 minutes with a toothbrush and a dishwasher liquid
just nothing literally just scrubbing it with a dishwasher liquid here how it looks like
i mean it's so shiny that i don't need the torch that much when i can do it it's
quite good so i feel let's turn it around so if you look
how shiny it is literally everywhere even the valve i can't reach that far but this is uh
quite clean uh throughout as well as here you can see how um clean it's everywhere
let's have a look at that part i haven't yet dried it up and still a bit on the on the wet
side so i have to dry it up and then put it on the car okay some shots before and after and this is
i've taken these shots screenshots from from the actual video i just put them next to each other
before and after this is the EGR valve before cleaning with the egr cleaner and you can see
there is quite a bit of carbon so after i mean i literally cannot see any difference between the
two i mean i tried to find exact same shot exact same position but i couldn't i did my best but
i should have thought about this and positioned them but you can see how carbon is
really everywhere here as well these are just imperfections from the egr valve itself it's not
it's not carbon buildup but you can see how these are really exactly the same and i have one that is
after uh manual cleaning i mean i couldn't really get the camera to to focus because it's so shiny
so clean but you can see what the difference is like how clean this surface is compared to
this i mean this is just before and after with the manual cleaning with just a toothbrush and
dishwasher liquid so another another one of these so you have quite a quite a bit of carbon uh
around here and as well here and this is after the literally the same amount of carbon this is just
an imperfection from the egr valve but literally the carbon buildup is is exactly the same
and this is after i mean you can see i've i could have i only spent 10 minutes with a toothbrush i
could have made it even more shinier but you can see how these are just imperfections but
they're covered with quite a lot of carbon where here these imperfections look like imperfections
rather than here covered completely with with carbon here is quite shiny because they managed to
stick the toothbrush in there so this is before and after on top where the shaft is for the egr
above and you can see quite a lot of carbon here got literally the same amount of carbon after the
egr cleaner here it's quite carbonated you can see the same amount of carbon uh so this is after
a manual cleaning you can see how shiny it is i mean literally the the light is bouncing off the
the surface so i cannot really get maybe just too much light but compared to this the rod
spotless here is completely spotless over here is still uh quite a lot of quite a lot of carbon
and i think last of these so you can see how uh this is the electronic part the top part there
is quite a bit of carbon buildup around here it's literally the same amount of carbon that is built
here i mean i saw these four dots here and exactly the same four dots here of kind of carbon buildup
this is a bit shiny because it from the taken in and out i've basically scraped the carbon
and this is with the manual uh cleaning i mean you can see how i mean there is still a bit of
water because i just cleaned it with a toothbrush with water it hasn't evaporated but it
you can see how clean this is as compared to that one and so final words and to answer the
question can you clean the egr valve with just spraying an egr cleaner in the intake
and the EGR valve will be clean uh the answer is absolutely no you cannot clean the egr without
using one of these sprays and you can see the evidence in the video i mean there's literally
no difference i mean they could be better cleaners that you can spray and they will work
but this was the one that i could buy from the shop just picked one i mean the others but i'm
not going to repeat that experiment because i mean i sincerely doubt that you can clean it
manual is just the best see that video for cleaning the egr valve
and unfortunately you have to do it manually thank you very much indeed for watching
let me know for any comments in the comment section thank you very much indeed for watching
well dropped the gasket, dropped the gasket down there hopefully it's dropped on the floor rather than
somewhere in the engine jesus christ i was lucky dropped down on the floor rather than somewhere
down the engine so that's a bit difficult to put together with egr valve let me see again
nice
I know not to pull this too hard that's what happens when you pull it too hard
