Crank Case Breather Fitted Today

Only ordered the thing yesterday so delivery was super fast. ITG are always great quality and this was no exception. Great moulding, good strong foam outer with wound metal inner.

All I wanted was something easy to clean and more importantly something to stop the oil recurculating into the inlet and rest of the breather pipes - not my ideal solution (which was the catch tank) but an easier one and cheaper one.

note ive blanked the breather inlet on top of the air filter housing with a rubber grommit.

looks good, but wont this mean that the sticky oil mess will just be spread around your engine bay instead?

Yeah, they do leave a small oily residue in the engine bay - my VTR used to love leaving oil around that area for me

The oil vapours in the drivers area can cause MOT issues too...

I ran a pipercross item (one that semtex brought off me) for 3 years on the S1 (longer than anyone I know on here) and not a drop of oil escaped - thats the whole idea - the mesh and foam retail the oil and allow the air to escape.

I think from memory I cleaned the pipercross on the S1 once or twice in those 3 years.

This is far better than the piperscross ones as it has the foam outer layer aswell as the mesh.

cant say ive ever had any fumes either????? you get the odd wiff of oil when you lift the bonnet but thats about it.

As for MOT problems it wont be a problem - its an easy 10 second job to change it back to the OE pipe, and thats if the MOT pick up on it - which they never have before.

Fingers crossed should work well.

Some oily crap does indeed come out of th erocker breathers, and deffo some fumes get into to cabin, you have to be careful I have felt sick a few times and can only really say it started happening more after I did this.

At the moment I have more oil coming out my dipstick tube though...

As I mentioned earlier, I never seemed to have any problems with 3 years of use on the S1, hence why I would use a rocker breather again now on the S2.

I expect everyones had their own experiences of them which is fine - mine have always been good !

No oil came out or no fumes entered the cabin.

to me 99% of engine bays smell of oil/dirt/petrol/grease anyway.

on another note, i forgot to mention I was thinking of using the breather hose I had brought for a tank to relocate the breather elsewwhere, but it seemed a bit pointless adding extra bulky tubing to the engine bay so I left it on the rocker - opinions welcomed whether to move it using the extra metre of tubing I now have.

I have one of those on my hybrid temp engine and it spits oil out left right and centre. I'd have gone for a catch tank, then mount that filter on to that to let it breath.

Yeah I would go that way too if I could be bothered, I have a nice pool of oil on teh inlet manifold finger and my blue HT leads are not oily brown.

Still it's better than that crap getting into the inlet manifold and gumming up the vacuum pipes etc as it was doing.

What was wrong with the o/e pipe that you felt the need to fit this breather thing?

Mine dumped a lot of oil into the airbox. Hence it still dumps a lot of oil but now onto the rocker and inlet manifold. I was forever having MAP sensor troubles with blocked vacuum tubes.

Looks fancy, not sure if I'll be doing the same tho. Haven't had problems with the OE system, just give it a clean out every so often and its happy as larry.

More tempted to get a proper catch tank/breather thing on the go.

Question

Have i missed something? but what difference does it make? if you filter it or draw it into the air box?

The difference is I dont want my inlet and breather pipes full of shit.

The pipe from the rocker takes oil and oil fumes into the air box lid and through another pipe into the manifold as per any modern car (emmisions regulations)

Trouble is the inlet and pipes are thusly full of this gunk - so the breather still allows the crankcase to breath yet doesnt send all its shit into my inlet and breather pipes.

I was getting sick and tired of everytime I was doing a job around the air box or mani that involved taking the breather pipes off getting covered in manky oil. Plus i can see how blocked breather and crud going into the mani helps effeciencly TBH.

As I mentioned I managed to run one successfully for a few years, hopefully this will be the same.

When I actually did a job in the S1 taking the throttle off the inlet and throttle were full of oily sludge and the inley mani had a mini lake of oil in - cant be good for the running of your car can it.

It may even help with performance slightly, as having hot oil fumes going into the intake is not going to be doing any good! Surely you want cold air with lots of oxygen, not nasty oil...

Hey I commented positively, just there are negative points aswell but IMO I will not be removing my rocker filter as I had serious running issues with all the oil in the inlet.

Same problem with the standard setup too!
Now I have a open setup with a green filter. Works much better and no more messy fluids in the airbox!

if anyones interested I have moved the breather towards the front of the car as this way IF any fumes or oil were to cause problems it will be in a nice open space.

ive made up a zinc plated bracket and the filter is secured using a mixtue of stainless jubilee clip and cable tie.

The breather hose now runs from the rocker down the side of teh battery and to the front of the car and filter - easy to remove and doesnt get in anything elses way should I need to fix anything.

Plus it was getting cluttered around the rocker area with the strut brace now there.

Very tidy, I like it!

Would it be okay for a cheapskate to just have the tube dangling down without the filter?

cheers, probably best not to just have an open tube. The oil and fumes (emissions basically) are suposed to be re-circulated not open vented at all, so atleast the filter stops oil frrm being dumped everywhere and stops alot of oil fumes. For an MOT it shoud be a recirculating system but no where ever notices, its not exactly noticeable - and if it is its 10 seconds to put the OE tube back on. It will never get pulled up in an MOT - id be amazed if it did.
