Looking for some top tips guys!

Is it common that when you replace the standard breather set up with the Bailey Breather, that the car won't idle and needs adjusting?

It is commented on in the S2 FAQ/Tips document that you might have to do it.

Second hand Bailey Breather, Brand new hoses.

Changed as a result of the dip stick/oil filler cap being blown off on high boost, and not idling.

On normal idle, removal of the dip stick/ filler cap would result in the car stalling as expected, indicating a potential blocked standard breather and not rings!

This is why I upgraded the breather.

Any and all rst (on mfi) will stall if you remove the dip stick, so your breather was fine, don't give the car full boost for the sec as it will be running lean.

I will look though some old pics of mine, but make sure every thing is connected to something and nothing is sucking in air, ie no big leaks into the system.

The one that goes to the bottom of the breather?

Or the one that used to got to "R" of the removed AMAL valve?

The bottom breather hose goes to the crank case breather hole,

Not sure whats going on with a hose from the amal valve????

the one that comes out the side of the metering head.think it is to the amal valve which you know about.

Breather Top Left - Rocker LHS
Breather Top Right - Rocker RHS
Breather Straight Down - Block Oil Return Beside Filter
Breather Angled Down - Meetering unit.

As the AMAL is completely removed (Bleed Valve), The hose from the front of the metering beside the breather hose that would have went to 'R' is going to atmosphere!

Did you blank off the one on the inlet

are you sure the one thats going to atmosphere is meant to be.i thought it was meant to be blocked off.or am i thinking of the breather hose on the metering head.i havent done one in ages so my memories a bit vague.

T28 RST

The one from the bottom of the breather can be blocked off from the metering unit, have you done this correctly

Oranoco

KE Jetronic can't go to atmosphere as the system see's it as an air leak and it won't idle/run

JamboRS

yes it can
block the return to metering head and it will run fine

the breather cant unless metering unit side is blocked but the amal valve can allthough i would not use a bleed valve as they are shit and provide a poor boost curve whearas a properly set up re jetted amal valve can work perfectly

Oranoco

There's nothing wrong with a bleed valve providing it's fitted and set up right and then, crucialy, not fucked about with. Sure it's crude but it does work

JamboRS

there a echo in here

my boost curve was the same with amal and bleed valve,if the actuator pre load is set correct you can bleed off the boost using a bleed valve just the same as an amal valve,its easier to fine tune a bleed vlave on the rollers thoug it takes away the safety that the amal valve gives.

The LHS side of the inlet had 2 x t-pieces cut into it.

To remove one of the t-pieces, the LHS now has the boost gauge and the dump valve off it with 1 x t-piece and the RHS one now has the OEM hose that came from the LHS!

I will get a bolt from work tomorrow and block it off, but what is strange is that I never touched it and only noticed it when I was replacing the metering-breather hose.

brand new hose from the breather to the metering.

Cool

As above I will get a bolt from work tomorrow and see what happens.

Thanks again for all your help!

Thanks guys for all your hints/tips & advice, idling issues all sorted tonight.

Bolt and jubilee clip into the redundant amal valve hose to the metering and a twidle with the idle screw got the idle set at about 950rpm.

Job done!
