Default Squishy brakes, dingy intake valve, and bubbles in my oil

Multiple ?'s here (sorry)

1) Is there specific patternt to bleeding brakes. I have the bleeder valve open while someone steps on the pedal (car running) and I tighten once fluid comes out. My brake pedalhas a lot of travel in it before it grabs. Am I doing it wrong? New front rotors and pads, and new shoes in back.

2) I took my intake off and noticed the valve in the intake manifold has a thin coating of oil residue. Is this normal for a 116k mi car?

3) little bubbles in oil = new headgaskets...right? Are they easier to service fomr UNDER the car?

I can only help you with the first question... Your procedure for bleeding the brakes is *slightly* wrong. What you want to do is (with the car off).. push on the brakes and HOLD the pedal. While holding the pedal open the bleeder screw, fluid will gush out.

With the person still holding the pedal, close the bleeder screw and repeat. You want to repeat this untill new fluid is being pumped out before moving off to the next wheel. I just did it the other day with my '03 TS and it took me just a tad over 1L of brake fluid (I had plenty of fluid tho so I made sure everything was flushed well).

Looks here for
instructions.http://forums.nasioc.com/forums/showthread.php?t=882153

Unhappy

As jonney_boy said, you don't need to run the engine while doing this. The pedal will feel a little different this way but that's okay. You might be closing the bleeder screw too quickly as the fluid comes out - this will require more iterations to bleed the brakes. Just make sure the pedal does not come up before you close the screw.

For the intake, there will be crud in there from the PCV - this is how emissions work, by collecting the stuff blowing around the crankcase and sending it back through the intake. You might want to check you PCV since my 135,000 mile one looked like this:


Finally, on the headgasket....I think I am in your hell too. I haven't had a chance to check out the water pump to make sure it is spinning at all. Check your coolant hoses at temperature. If the top one is hot but the bottom is cold, you are in my hell.
To really scare yourself about this, check out this thread.

I just bleed my brakes by opening the screw, tell the person to steo on the pedal. Have them tell me when it's all the way down, then I tighten it and repeat till fluid is clear with no bubbles. Just make sure the fluid doesn't get too low resevior. refill as necessary. and if your bleeding all 4 wheels, start with pass front, driver rear, driver front, pass rear.

You may have gotten air in the master cylinder and might need to bleed them for a while before the bubbles get out.

It should be noted though that i bleed my brakes really often so the fluid is always in good shape (I race a lot) and there's never many bubbles or debris.

I recently started using thread tape on my bleeders threads. It keeps air out during bleeding.

I used to use a piece of clear tubing and a jar. You attach the tubing to the bleeder and open the bleeder. set the other end of the tubing in the jar and pour enough fluid in there to cover the end of the tube. This will keep air from going back up the tube. Then all you do is pump the brakes slowly until there are no more bubbles in the line.

You can also just open the bleeder and let gravity do it's job.

I recently bought a mityvac. I really like it. Pretty versatile tool.
