Hi...decided to change the breather which has a small crack in it with a new one...you should see the crack where it
connects to the rocker cover

Posted Image

But stealership prices stopped me...asking 19 euros just for the front hose...and not in stock..so went second hand..found this for 5 euros

Posted Image

Asked would there be a problem...guy reckons no but the difference in the holes seen here...DID

Posted Image

Vacuum holes are different, so I wanted to monitor what might happen...

Put the replacement hose on....waited no difference in water temp...good...oil pressure, nah same crap 1 point
something...so I took it for a spin....

What have I done...well amazingly that pedal response is awesome!!!
Car reacts as if cold and just goes...still have this wooshing sound at high revs as if the auto is going to slip...but nope....it doesn't....car just accelerates..

Now I live in a very steep hill area...so coming back up I got the shock of my life.
Car now starts in 1st when hot and pedal pressed half way down.
WOW, this is totally a different car now, so I stop, still going uphill...pressed the pedal only a 1/4 down...2nd gear start...but with no hassles...car still has the power to go!
Last testing...stop again...press the gas slowly..then a little lower, and 1st goes in WITHOUT the kickdown.
Water temp still hot 85 ish... so I decided to let it cool down for a few hours...

Cold-warm...she starts in 2nd but goes...press kickdown 1st goes in....as for when hot, well same thing 1/2 pedal down first goes in and just drives off like a dream...

So please could someone tell me WHAT I HAVE DONE...is this just plain lucky OR will I be damaging anything?

sometimes its better to bite the bullit and buy new, my 16v rear breather pipe from rocker
runs metal pipe through it, this I replaced new at £60..

second hand aint worth the hassle plus there's no guarantee on the part..

While your correct to point out that there is no warranty, part would have come after ?? days from germany!
Plus to drive out to muma merc is a good 30-5 km...second hand is just 4-5 km away, has another 10 of those hoses...
Do the maths, it's not like I'm going to be changing them frequently.

Anyway if you look at the 2 long hoses closely you'll see that there isn't that much difference,I was going to put a hole in
the second one IF car wouldn't work, cause that was the ONLY difference...but I opted to change the back one also with the
other one with the results that I got... amazingly to the better...

By blocking it's nose mate... :lol:
My query is this just a fluke, or did that little crack do that much difference.
Where does the back hose go to, cause that's the part that has been blocked off.


Anyone got a diagram of the vaccum hoses...ruski site not available...

Anyone know the name of it, In Northern Ireland 190E's are a rarity and even getting a hose like this is difficult!

Mines from a w124 2.0 litre...as for yours... your air filter housing is also different

It would normally be called a crankcase vent hose, not sure on the merc but if you say that they should know what you mean. Its common to go as the fumes cause the rubber to go hard over time and the vibration then cracks it.

Would it affect the car in any way of performance having a cracked one?

I changed this item on my car a few months back, didn't notice a huge difference if any at all in the performance of the car. It cost £5 or less. If it was really expensive I'd have remembered. Shall check as I'm sure I have the receipt from the dealers somewhere.

It will slightly effect it but I wouldnt have thought massively. You never know though. I am actually replacing mine as you often get a bit of oil leaking out of cracks that goes all manky.

It will suck a bit of air into the filter box that may effect the temp of the air overall. I would expect it to be slight but warmer air means less power.

The main effect would probably be on the vacuum system and all the devices that monitor it. I would expect this pretty minor as well but its very hard to tell.

Probably merc dealer only but if you can get the part number you can use mercedes-benz-parts.co.uk , dont forget we get an extra discount.

Mine is second hand and would be a different part number anyway.

One other thing I forgot to mention is the very thin hose was halved in size.
Could this also affect performance?

Isn't that hose part of the 'Emission Control System' and it has a metal 'cooling' pipe running through it,

that's why it is so expensive to buy, I don't know for sure whether it is the same on all the 190 engines,

I would advise a visit to the MB stealership and check your model and price before committing

yourself to buying new. ;)

Dig deep stuu lmao

Did you ask the price before ordering.

Mostly it's three pipes in one to change

as if one is gone the other two will be well on the way.

I think total price around the £40.

It came to £12 including p&p. It's not the same hose as the one arkudos got.

Yes stuu I think it was the 'rocker box breather' that you got,

But the 'crankcase breather hose' is the other one which comes dearer.

it has a metal cooling pipe running through it.

I'm not sure if it is of the same design fitted on all models .

Oh right, what does the crankcase breather hose do? Where is it located as I'd like to have a look at mine and see if its in good condition

If you have a 'Haynes' number 3450, have a read of pages 4D.2 and 4D.3

it's all to do with the 'emission control' to reduce the unburnt carbons etc.

from the crankcase being released into the atmosphere, they are sucked or

blown into the inlet manifold to be burnt.

Does anyone have a diagram or pic where the crankcase breather hose is located? I checked the haynes manual, it does mention it but no idea of location or picture.

I changed all if the vacuum hoses on my first 190 and it fixed all of its running problems and transformed the way the car drove completely.

When the hose starts to crack, its common for people to try to tighten it with a metal jubilee clip as in the earlier pictures but this tends to mis-shape and distort the hose around its fixing and can make the problem worse.

For a small cost, a replacement is a better option.

You only need to look at any thin plastic piping coming off the inlet manifold, which is where the vacuum is generated. There's quite a few, any of which can cause vacuum problems if they are leaking.
