I went 2 check my engine oil, (944 S) unscrewed the cap 2 top it up and noticed a thin cable I had never seen b4. As I took hold off it it came more free. Iv read that the ideal control valve stabliser can come free from removing the oil cap. It had a small blue clineder about the size off a pound coin and a about 20-30 mm tall. It had come unplugged from a tube that sits behind the oil caps neck. Was a right pain 2 plug back in due 2 the lack off space 2 hold the tube while it was push fitted. There's a branch then a similar if not same size tube which plugs in 2 a larger canster thing on the fule rail. That then came free, so I undone the main hose 2 the oil caps neck plug them both back in. Much easyer then before.

Sorry 4 my lack off knowage. I'm just wondering what these are? And there persouse. I'm guess there vacuum lines?

Is there anyway 2 ensure a tighter fit?

It sounds like vacuum lines and the one way valve. Have a look at the diagrams on Lindsey Racing's site for the vacuum tube diagrams.

I think the blue valve you mention is the one at the top of the diagrams that appears to go nowhere.

So iv it was 2 come parted again unnoticed what would berth results?

Thank you very much, this is all a bit new 4 me.

From what you're describing it sounds like the valve on the brake servo as that's the only small blue cylinder I can think of. Not too familiary with the vacuum layout on the S though so can't be too sure.

Your heater will be stuck on Hot if this one way valve is disconnected.

There's a 3 way connection before it and the left branches over though the fire wall 2 the black bullet shaped thing, I think it's a vacuum. Are get a picture.

So is it really possible 2 deconext the ivs when removing the oil cap?
