Replacing the Head Gasket

WITH PICTURE 

Starting Procedures:

• Open Hood.
• Disconnect the battery.
• Drain coolant.
• Remove airbox assembly - unbolt from rear of head.
• Unplug wiring harness and strap it out of the way.
• Remove the coil pack and wires.
• Remove ground strap from head.
• loosen and disconnect EGR valve from head. Actual removal from
  engine bay unnecessary.
• Unbolt intake manifold from head.
• Remove spark plugs from head.
• Unhook Fuel Injection Assembly from fuel line.
• Remove Fuel Injection rail/fuel injectors from head. Note:
  Was informed, not a necessary step
• Remove alternator belt.
• Remove valve cover.
• Unbolt exhaust from exhaust manifold. [Beth Boose wrote: "do not
  unbolt exhaust from head- after everything else is removed, place a
  jack (with a block of wood on top) beneath the catalytic converter and
  slowly jack the cat up, this will pop head free- no need to pry the
  head up. Then unbolt the exhaust from the cat - it's easier to remove
  the exhaust bolts with the head off the car.]

I might have left a few things out, but you basically remove
everything and kep track of where it all goes. I take pictures. I have
a digital camera, but a Polaroid will do.

Now we start getting to the fun part:

• Jack the right side of car til the tire is off the ground and
  support it.
• Remove the front tire.
• If you replaced the engine cover, remove it again.
• Loosen air conditioning compressor, then remove belt.
• Remove power steering pump/belt if applicabe.
• Remove crank bolt.
• Using the puller, remove the crank damper/pulley.
  • Removing this can be a real pain. Fortunately for me, mine came
    off easily. We had one that was very difficult at first. We actually
    broke one pulley. We then spayed it heavily with some PB Blast (there
    are other penetrating oils available) and let it sit overnight.
    Probably wouldn't hurt to hit the crank damper/pulley with a rubber
    mallet to help the oil penetrate. Other people have used a torch to
    heat up the pulley. There is a puller specific for the Chrysler
    2.0/2.4. This
    is the one SnapOn sells.
• Remove front timing belt cover.
• Place floor jack with wooden block under the oil pan. Raise jack
  til block touches the pan. You can use the floorjack to raise/lower
  motor to help with clearances.
• Unbolt/remove engine mount.
• Rotate the crank until the timing marks on the gears line up with
  the cover.
• Remove tensioner.
• Remove timing belt.
• remove timing gear from head/camshaft.
• Remove rear timing cover - if you plan on changing the water
  pump.

Now, since so far, we have done all the procedures to remove a
timing belt, it would make sense to use a new belt, so we don't have to
do the labor twice when unnecessary. The timing belt's recommended
change interval is 105,000 miles. I changed mine at 127,000 miles when
I did my head gasket.

On another note, you have to go through these procedures to get to
the water pump. Usually, they would charge another 1/2 hour labor to do
the change the water pump. A water pump's life expectancy is not much
greater than 100,000 miles.

Some say you should remove the cam from the head. If you want to
examine the cam lobes and actuators, you can remove the cam. I didn't
when I did mine. If you have a DOHC motor, you need to remove the cams
to have adequate clearance to reach and remove the headbolts.

• Remove thermostat housing.
• Remove headbolts.
• Loosen the head from the block by rocking and careful use of a
  prybar.
• Lift the head with the exhaust manifold and remove from the car.
• Clean all surfaces - block, head, intake ports.
• Check surfaces for warpage - check specs in service manual.

The assembly is pretty much the reverse of disassembly. A few notes:

• Use new head bolts if you are worried or the originals are
  stretched. (Some people recommend simply always using new head
  bolts since they do not cost very much.)
• Make sure you tighten the bolts to specs in the correct order.
  Refer to the manual.
• Replace the rubber grommets in the valve cover.
• Replace the tensioner with a new one. It might not be necessary.
  I have 170k miles on mine. But a friend of mine, his Breeze's tensioner
  broke about 3k miles after his headgasket replacement. So, you might
  want to be safe than sorry. (Editor's note: if you use the old one,
  make sure you reset it.)

How to Crack a Wi-Fi Network’s WEP Password with BackTrack

— You already know that if you want to lock down your Wi-Fi network, you should opt for WPA encryption because WEP is easy to crack. But did you know how easy? Take a look.

Originally published last year, we wanted to revisit Gina's awesome guide to cracking Wi-Fi WEP passwords for Evil Week. Alternatively, if you're not in a reading mood, check out the video version.

Today we're going to run down, step-by-step, how to crack a Wi-Fi network with WEP security turned on. But first, a word: Knowledge is power, but power doesn't mean you should be a jerk, or do anything illegal. Knowing how to pick a lock doesn't make you a thief. Consider this post educational, or a proof-of-concept intellectual exercise.

Dozens of tutorials on how to crack WEP are already all over the internet using this method. Seriously—Google it. This ain't what you'd call "news." But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes.

What You'll Need

Unless you're a computer security and networking ninja, chances are you don't have all the tools on hand to get this job done. Here's what you'll need:

• A compatible wireless adapter—This is the biggest requirement. You'll need a wireless adapter that's capable of packet injection, and chances are the one in your computer is not. After consulting with my friendly neighborhood security expert, I purchased an Alfa AWUS050NH USB adapter, pictured here, and it set me back about $50 on Amazon. Update: Don't do what I did. Get the Alfa AWUS036H, not the US050NH, instead. The guy in this video below is using a $12 model he bought on Ebay (and is even selling his router of choice). There are plenty of resources on getting aircrack-compatible adapters out there.
• A BackTrack 3 Live CD. We already took you on a full screenshot tour of how to install and use BackTrack 3, the Linux Live CD that lets you do all sorts of security testing and tasks. Download yourself a copy of the CD and burn it, or load it up in VMware to get started. (I tried the BackTrack 4 pre-release, and it didn't work as well as BT3. Do yourself a favor and stick with BackTrack 3 for now.)
• A nearby WEP-enabled Wi-Fi network. The signal should be strong and ideally people are using it, connecting and disconnecting their devices from it. The more use it gets while you collect the data you need to run your crack, the better your chances of success.
• Patience with the command line. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient.

Crack That WEP

To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.

First run the following to get a list of your network interfaces:

airmon-ng

The only one I've got there is labeled ra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).

Now, run the following four commands. See the output that I got for them in the screenshot below.


airmon-ng stop (interface)
ifconfig (interface) down
macchanger --mac 00:11:22:33:44:55 (interface)
airmon-ng start (interface)

If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully "faked" a new MAC address on your network interface, 00:11:22:33:44:55.

Now it's time to pick your network. Run:

airodump-ng (interface)

To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else.

Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands.

Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:

airodump-ng -c (channel) -w (file name) --bssid (bssid) (interface)

Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose "yoyo," which is the network's name I'm cracking.

You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:

aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) (interface)

Here the ESSID is the access point's SSID name, which in my case is yoyo. What you want to get after this command is the reassuring "Association successful" message with that smiley face.

You're almost there. Now it's time for:

aireplay-ng -3 -b (bssid) -h 00:11:22:33:44:55 (interface)

Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the yoyo network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the "#Data" column—you want it to go above 10,000. (Pictured below it's only at 854.)

Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the yoyo AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many.

Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:

aircrack-ng -b (bssid) (file name-01.cap)

Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.

If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:

The WEP key appears next to "KEY FOUND." Drop the colons and enter it to log onto the network.

Problems Along the Way

With this article I set out to prove that cracking WEP is a relatively "easy" process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.

So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline.
