The Ford RS Forums.

Hi.
I am new here and I am pleased to be here in your RS Cosworth forum. I have recently bought a Sierra RS Cosworth with YB engine and I am now working on it. I have stage3 injectors (Light Blue) and stage3 MAP (EPROM)
I hope to have nice time here as well in my Cossie!

I would appreciate your help on few things I am having problems with:

My engine is getting to much of fuel, smells af gas and gas in the engine oil. Does anyone now how to fix this? Is it the Fuel Pressure Regulator valve? See picture 1. I opend it and it was rusty inside, so I put some lubrication/oil in it from the top where it is adjustable, but I am not sure what do do.

Should the Blow Off valve take air in? Picture 1 to the right of the Fuel Pressure regulator valve. I am wondering if it is broken because when in idle it seems to take air in..?

Sensor? For oil? Where is it located/should be?

There is one tube missing here, do anyone know where it should go?

Thanks!

PS:Where is Idle Speed Control Valve? Function?
- the engine is running unstable on idle (up and down in rpm) could it be this valve?

Is there no AirFlowMass meter? If yes, where is it located?

Is there no Lambda sensor (O2)? If yes, where is it located?
