just about to purchase a breather for my saff 4x4 as the standard set up isnt coping with stage 3 and is chucking oil, everywhere under the engine bay.

was thinking pro alloy, as they do good service on here and as far as i am aware it has 4 pipes.

1. top one to fitting under turbo (17mm hex, can have this machined at work) (instead of drilling cam cover???)
2. other top one to kidney box fitting, do i remove the red plastic part.?
3. small pipe to oil drain to sump(where do i find this fitting?)
4. vent to atmos under car, via long pipe?

also does having a/c complicate things as i have the large pipes running over the inlet, and where does the actual breather unit bolt to?

would i be better off with the mirror image one?

any help with this much appreciated

cheers

1. Sorted
2. Yes remove the red plastic rubbish above the kidney box.
3. You can buy goodridge fittings (adaptor and hose tail), to fit return into the sump plug hole (unscrew return pipe to drain oil).
4. Sorted
This is exactly how i fitted the breather to my old 3dr.

Breather normally bolted to bulkhead plastic stuff next to battery.
Mirror image tanks are coslty IMHO.

The mirror image is alot easier with air con mate...

Yes you remove the red part off the kidney box and blank the inlet plenum.

The drain to the sump is under the turbo , the knock sensor wiring harness mounts to the plug in the block, remove the harness bolt and then you will see the erm 19mm it think plug under it.

Buy a fitting kit from whoever you get the tank from, and they come with all connections and pipes and instructions.

 

ahh if you are using the drain plug as a second vent instead of the rocker cover, think you will need to mod the sump to allow a drain back under the oil level.....

 

cheers for the help guys. i am a little confused now.

why do i have to use a different returno to sump if i use the different breather on the top?

surely they are both crankcase pressure?

 

Normally the second breather is in the cam cover, but you would rather use the blanking plug under the turbo in the block (good idea).
However, normally this is used for the oil return hose.

So instead use some fittings to plumb the oil return hose into the sump plug hole, as this is the ideal location below oil level, so there is no crank pressure blowing the oil return back up the pipe into the breather tank.

Hope it makes sense.
If not speak to GGR, i got the advice from them.

 

oil return from where? is this at oil pressure? or just carry oil vapour?

dont really get this bit. so you cant blow crankcase pressure into the breather? so why fit the breather at this point?

cheers for the help

 

the return is to let the oil go back to the sump, this cannot happen when it is at crankcase pressure.... it would only happen when you switch the engine off, so they put the retern below oil level so it can retern all the time when engine is running as it is not seeing the crankcase pressure.

 

normally you would have...

one hose to the rocker cover (breather)
One hose to the kidney box (breather)
One hose to the bung under the turbo (drain back)
One hose to atmosphere (air release)


But to make the system work better ,

One hose to the bung under the turbo (breather now)
One hose to the kidney box (breather)
One hose to the sump bung (retern under oil level not at crankcase pressure)
One hose to atmosphere (air release)

 

As above

 

cheers guys

now all i need is a decent return to under oil level, any pics or ideas of fittings? have heard the 4x4 sump is a pain to remove, no probs making a fitting, just getting it off

 

use the sump drain bung.... you can buy an attachment i think... ferk taking the sump off thats almost engine out mate.....

 

This may be a stupid question but is it the same for a 2wd

 

Hi,

I cant begin to imagine cranckase pressure high enough to prevent the oil draining back through the normal route for aftermarket breathers!!! Not unless of course your engine is totally shot causing a serious amount of blowby, you will be needing more than a breather kit to sort that

A four cylinder engine (even turbocharged) keeps the very slight cranckase pressure fairly even throughout the engine so this should not be an issue. Also some aftermarket oil temp gauges need the sump plug adapted for the sender units

I reckon it is wise to get a breather in the top of the engine, A lot of condensation gathers here and creates that mayo crap.

I had a billet alloy oil filler cap made up with a swivel coupling and take off pipe for the breather as I didn't want to drill out my cam cover, this works very well, and mayo is not an issue in my engine

The swivel coupling allows me to remove the filler cap to top up oil without disconnecting the breather pipe.

dig up an old thread on this subject. stu explains this breathing return problem....
