DIY Induction - Oil Breather?

Danny133 · Mar 31, 2014

Okay everyone is making them .. but where does the oil breather pipe go once you loose the standard hoses?

What do you attach it too and how? Sizes and guides?

Midnight · Mar 31, 2014

The one behind the engine that goes to the plastic filter elbow?

Either put a small 'oil breather' on the end or put it to an oil catch tank depending on what you're after.

Danny133 · Mar 31, 2014

What size breather would I need and where do I attach it so it's not flopping about like a rag doll? - don't know what a catch tank is so I won't even attempts it

172Ben · Mar 31, 2014

about 14mm should be fine

Midnight · Mar 31, 2014

And attach anywhere higher than the outlet itself I was told.

MartinR · Mar 31, 2014

Catch tank is the best option imo.

Or as said slightly above the outlet hight. Don't just wack a breather on the end of it as it will clog and drip on the exhaust manifold

Danny133 · Mar 31, 2014

What's a catch tank and how is that fitted?

For the hassle.. just buy a proper hose, or buy a hose joiner where you drill a hole in the hose itself and insert the nipple and use a nut to secure it on the inside

Not an oil breather which seems to be a 5 second job?

Catch tanks are easy! Fit your DIY induction kit (I'm contemplating one, routing it down to behind the front N/S wheel!) and then run a hose from the rocker cover oil breather nipple to the catch can, and then fit the oil breather filter to the other catch can hole! See my paint diagram!

Oil Breathers fitted to the rocker cover clog up with crap and go all horrible! Catch Cans means you can empty that crap out!

Damn, hoping you were going to say it was available to buy off the shelf.

Looks great though, really impressed with that!

That's just a breather yeah? No catch tank?

Midnight · Mar 31, 2014

It has a sight glass underneath just before the filter. Nice bit of kit!

Awesome that is Pat. Great bit of work!!

I want.

This is mine, the catch tank is now located between the pas reservoir and the coolant bottle. Looks alot tidier now (need to get an up to date picture)

Midnight · Mar 31, 2014

I've been looking all day for something like it. Think I'm going to DIY one with a 'test tube'. Will not be as good as Pat's but will cost less that £5 and serve as an extremely small catch tank.

imprezaworks · Mar 31, 2014

Looks great. Maybe pat could make a couple more?

Yes, Yes, Yes I'd have one!

imprezaworks · Mar 31, 2014

Pat 182 get it sorted

Pat 182 · Mar 31, 2014

Wasn't planning on doing another let alone afew more??!! lol

The machines I use at me dads are tied up for a while making bits for old motorbikes?! Sorry

My dad make twin leading shoe front brake plates for BSA GOLDSTAR'S

Pat

Pat 182 · Mar 31, 2014

Here's some pic's of them

rerly are very good
Cheers Pat

Midnight · Mar 31, 2014

Booooo Pat, I really do like the oil breather set up. Best one I've seen!

Pat 182 · Mar 31, 2014

Never say never mate

the one on mine took forever?! May have alook at some less machined jobbies??!!

The brake plates above have so much machining on them and it takes a lot of time!!

Here's my tank mounted on the ECU bracket.

Hose joiner is a 5 second job.. cheaper than buying filters/catch cans/additional hoses IMO

Just all seems a bit pikey and trying to save pennys when another £40 or so could get you a samco that would save all the hassle over an oil breather pipe problem

Whole idea is to get rid of the oil returning back into the inlet which in turn makes performance worse.

ThomasBrentnall · Mar 31, 2014

Pat 182 you could start a business here!

Your mate hasn't text me yet btw!!

Jules172 · Mar 31, 2014

I need someone to come and discard a few hoses and unessersary hoses etc on my 172, pat that looks awesome

I hear what your saying but honestly chasing performance on these cars is a complete waste of money IMO

Danny133 · Mar 31, 2014

I'll buy one

172Ben · Mar 31, 2014

This was mine

Its not really chasing figures. These cars are not getting any younger so it's just trying to maximise the OEM power really. Older/worn engines tend to use more oil and this oil goes back into the inlet in turn decreasing the fuel RON in turn loosing FREE power...

Danny133 · Apr 1, 2014

Sounds easier just to fit an oil breather on the end of the pipe tbh and cable tie it higher than the intake .. no fancy bracket but it will work

Pat 182 · Apr 1, 2014

It will indeed Danny

BUT if you have a heavy breathing engine it will soon block up and spray crap allover without a tank to catch it

My can/tank as caught nowt as we speak its like a copper lol must have nice engine??!! plus it looks right:approve:

Pat

Danny133 · Apr 1, 2014

I don't know how to pipe a catch tank not where to sight one unfortunately

so a breather seems like a better option for me!
