:K: Thx a million!! I just replaced my front and rear brakes and find that the pedal pressure returned after bleeding the brakes; HOWEVER as soon as I turned the engine on the pedal became super-soft again.

I was told the booster may be bad and I logged in to find out more info. Thanks to you I NOW KNOW where the booster is!!!

My PCV hose (the one that runs toward the front of the car) tore in half as I discovered last night, I couldn't tell you how long it's been like that.

Just wondering the potential troubles (if any) I could be facing with that hose just hanging open for the past few weeks (I estimate).

That line returns oil vapours to the cylinders to be reburned as a emission control. Everything around that could get oily (Including your belts), dirty air could get in the crack and get into cylinders, and you could experience a mildy off idle. I would just fix it.

Thanks for the diagram! I keep getting the camshaft position sensor code and needed to be sure it connected to the distributor! AND that Crankcase ventilation hose you speak of, MCROW, may have messed my timing up! THANKS!

What is the blue object between 9 and 10, and to the left of 21? I only ask because the tube leading into mine has been cut and "sealed off" with a screw by a previous owner..

 

[mcrow]

Its just a vacuum hose that leads up near the wiper motor, not to sure where it goes actually. It should be fine if its sealed.

Yeah the consensus I've received so far from about 4 people is it's nothing to worry about, but nobody seems to know what it is haha. My buddy has an Mk4 golf and I think he said his was cut too or something like that.

Help me identify please (Jetta 1996 GL)

I need to identify the Camshaft position sensor on my Jetta 1996 GL. I am confused because sometimes I see that some pictures shows it inside the distributor and sometimes they say that it is next to the engine. All I know is that the sensor in the distributor is called distributor sensor. Am I right?

Please help me to confirm is the distributor sensor is the same as the Camshaft sensor.
Thanks.

 

[mcrow]

Its always on the side of the distributer on these cars, and its also called the hall sender.

coolant

There is no radiator cap. You add it into the coolant reservoir (the blue cap next to number 22 on Mcrow's diagram).

thats badass

[mcrow]

You probably didnt get all the air out of the lines.

 

[JettaSetta]

The radiator doesn't have a cap. You add coolant through the reserve tank. Its the white plastic round tank in the right rear corner of the engine compartment. Don't attempt to open the cap unless the engine is cool.
