what do I do with the pipes which go to the oil seperator if I put a breather on the rocker cover and take away the oil seperator??

do I put a filter on the tube inlet manifold also and block the big plastic pipe to the metering head or am I meant to do something else with them?

any views appreciated

 

are you on mfi ? if you are i dont think you can put breathers to atmosphere as it will cause problems with running and starting ect

The breather system needs to be sealed on mfi

 

oh yeah I am on mfi, when the hose is disconnect from the rocker cover but still has the oil seperator on it runs well but if its all connected it stalls!!

the black oil seperator isn't blocked as I have soaked it in petrol and can blow through it very easily! what problem is this showing then??

 

Something else along the breather system could be blocked, have you checked the breather pipe that runs along the back? think its a hard plastic pipe

 

yeah I can blow through that really easy also! none of it seemed to be blocked or sludged but I broke the one way valve when taking that off to try see what was wrong!

could the valve cause it to stall if it wasn't working properly?? I can blow through it but its hard and won't let me suck air through.

really confusing, can't find any air leaks though

 

could be that valve, u even checked the breather down the back from rocker cover to crank case?

 

yeah te one which goes to crank case is rubber and is good, the big plastic one goes to the metering unit but also looks good!

its confusing lol

 

it can only be a air leak as it only happens when the breather is on, the flap isnt stuck on the metering unit is it?

 

no checked that also, is really free, I can pull it up by the nut and the car will stall! the pipe at the inlet manifold which I disconnected from the oil seperator is sucking really hard and cuts out if I cover it up!

is there any tests I can do which will help my situation??

 

if you rev it up and block the pipe off does it still stall?

 

no it revs like normal but if I let off the accelerator when the pipe is blocked it stalls

 

have you checked the hole inside the throttle body is not blocked and is the inside of the throttle body clean where the flap sits?

 

just checked and hole is clear but flap is little dirty round bottom edge but doesn't look like it would affect anything

 

still could be something to do with that one way valve matey, is must be on there for a reason

if you connect that pipe and run it without the oil filler cap will it run then?

 

no it still cuts out with filler cap off, it will run wih the cap off if the hose is disconnected though??

do you think it could be something to do with metering unit?? I'm really confused cause checking everything and cleaning it also

 

so its need air to run, so it compensating for something else thats not doing its job ie metering unit, could be

 

try open flap more on metering unit with breather system closed, then start it, if you got enough hands

 

or thats why i said make sure the throttle body flap is clean cos im sure there surpose to be a tiny bit open and if any crap is around the edge if will block the air flow

 

if i push the flap a tiny bit it stalls. i have cleaned the flap in the throttle body but the gap still look tiny, surely the hole lets in air before the flap into the engine though??

my metering flap doesnt really look as if its open! when the engine is off it has no resistance to this point which its at when the engine is on then it has the same pressure if i push it all the way down.

I feel like leaving the hose off and selling

 

get rid of the standard breather system.

block the pipe that goes into the metering head off with something then have the breather hoses from the rocker cover venting to atmosphere.

 

dave_y - if i block the hose going to the metering head it stalls

All hoses checked and on tight and nearly new sfs ones so no splits

What about sump gasket? would that cause this? I'm thinking of anything now lol

 

dave_y - sorry missread - i was thinking inlet manifold pipe.

 

if i blocked them all does that mean what ever is wrong will get worse or just wont notice it?

Also would the inlet manifold pipe need to be filtered as its sucking in alot of air! its sucking so much it sounds like a compressed air gun blowing

 

oh yeah and block the little pipe off that goes to the inlet manifold....

 

then it stalls if the inlet maniflod pipe is blocked. its sucking proper hard and only runs like that at the mo

 

here is my setup.

the rocker cover pipes go into the catch tank which then vents to atmosphere.

the little pipe on inlet manifold and the pipe going into the metering head have been blocked off...

 

i would do something like your setup but the top small pipe on the inlet manifold which you have blocked off, mine cant be at the moment so something is wrong somewhere on my car.

I can block and unblock the other pipes and the car doesnt mind but as soon as the top hose is blocked or put on the breather system it stalls. its should beable to still suck something through the breather as i can suck air with my mouth but it doesnt seem to be enough. its like the car is running from that tiny hole
