  1. There are three valves that control the evap system. One vent valve on the charcoal can, one on the fuel filler and one above the alternator in the engine compartment. Under certain conditions the evap system is tested for leaks. Something like, fuel between 1/4 to 3/4 full, engine at operating temp,etc... The two vent valves are closed and the engine mounted purge valve is opened to build vacuum in the system. Purge valve closed monitor vacuum. If leak detected throw a code.

    I would check the valves first as they are moving parts that wear. Of those the purge valve on the engine is the most active. Also If you do a search for 996 vent valve you will see a tutorial on the fuel filler mounted vent. That seems to be the one most folks change first.

    "Porsche 996 fuel vent valve" on Pelican parts tech articles. Good luck, don't forget to tell us what fixed it for you.

  2. Get a Bentley Service Manual before you take any more of the engine apart.

    http://www.amazon.com/Porsche-Carrera-Type-Service-Manual/dp/0837617103/ref=sr_1_3?s=books&ie=UTF8&qid=1437413883&sr=1-3&keywords=bentley+manual+Porsche

     

    The valve covers are also 1/2 of the cam bearings.  If you pull a valve cover you need to support the cams with "clamps" that hold them in place.  To check valve timing you remove the green plugs on the ends of the cam covers (without removing the valve covers) and check the "slots" in the ends of the cams while the flywheel is at top dead center. 

     

    The $300 set is more complete.  You might end up needing both tool sets.

  3. Sir Tools "Sir P 254 Engine Support Bar"  http://www.sirtools.com/stuttgart_05_page_2.pdf

     

    This tool is very helpful when you need to support the engine when you remove the transmission. 

     

    It makes pulling the trans much easier. Beats using a floor mounted screw jack. You can tilt the engine/trans to get clearance to pull the brackets out and replace them, move the lift up and down for bolt and slave cyl access etc. Also enables engine tilt to match trans during installation.

  4. These two tool sets make changing coils and spark plugs much easier.

     

    1. Kobalt "24 piece right angle bit driver set. #0338552"  SKU #09919852324

     

    2. Service Kits "3 piece spark plug service kit #41740"

     

     

    The small ratcheting handle in the driver kit allows you to remove the coil bolts with a lot less aggravation.

     

    The magnetic spark plug sockets are permanently attached to the extensions so you don't lose them in the plug wells. And the short extensions are perfect for the job.

  5. Make sure to put the mounting bolts back in the right places.  If you put a long bolt in the wrong spot you can break pieces of the engine casting.

     

    There is also a fancy tool that supports the engine while the trans is removed. It has an adjustable saddle that helps with lining up the trans input shaft. SIR Tools SIR-P 254 http://www.sirtools.com/stuttgart_05_page_2.pdf

    If you search they can sometimes be found for under $200.  I got a lightly used one for ~$100

     

    You can remove the slave cylinder from the trans and tie it aside so that you don't have to bled the clutch system.  You need to drop the trans a little to get to the top bolt.

  6. So after I donated this year my account was semi locked because emails sent to me were bouncing, old email was still in system?

      Now email is corrected.  Still get "fix email" popup window after every thread change, also at login.  Try to correct by filling out popup and get "That email is in use"  Well no S--t Sherlock it's mine.  How to get this straight?

    Thank You,

    Sorry this should have been a new thread.

  8. Sounds like a failed wheel bearing cage.

    The bearing is a double ball bearing. One side can fail and allow the balls to gather together and click like billiard balls while the other holds together for awhile. At Watkins Glen my garage mate had one (rear on an air-cooled 911) that was loose and he re-torqued it. It seized and spun in the carrier 2 sessions later.
