With some trepidation I approached the heads..
|
|
|
|
First I set the crank to 45deg after TDC. Just in case the cams moved while I was removing them.
|
|
|
|
I'm not sure what this is called..
|
|
|
|
I loosened the belt tentioner so I could take the cam gears off.
|
|
|
|
The cam gears actually came off very easily.
|
|
|
|
Underneath the cam gear is a thin plate which I removed also.
|
|
Underneath that is a triangular shaped thing. I'm starting to feel like an Archealogist!
|
|
|
|
Whew.
|
|
Then I removed the cam seal retainers.
|
|
I'm not really sure how effective they are since they're just plastic arms that seem to have some amount of flex..
|
|
|

Porsche recommends using a special tool to hold down the cams as you unbolt them since they under a bit of spring tension from the tappets beneath them. Since I didn't have this tool and it costs over $200, I took Susan @ Devek's suggestion and loosened each bolt on the top of the head by 45degrees working in a spiral pattern similar to the one used to loosen the head bolts.
|
|
After I had gotten all the bolts almost loose, I tightened the left-most and right-most cam bearings about 1/4 way down and then removed all the others.
|
|
|
|
Here's the cams removed - cam chain is still in place.
|
|
I next removed the cam chain oiler.
|
|
Then the Cam chain tensioner.
|
|
Finally the cam seals.
|
|
In order to lock the cam from moving when I undid the cam bolt, I had to create a slightly odd contraption.. (I actually had to do this for the passenger side too but I didn't take picture)
|
|
|
|
Both sets of cams removed.
|
|
I next removed the headbolts in the order specified in the manual.
|
|
At last! You can see the piston heads.
|
|
Same on the passenger side.
|
|
More pistons! We're getting somewhere now..
|
|
The incredible shrinking engine..
|
|
Next I removed the oil strainer thing..
|
|
|
|
Here's all the parts semi-neatly organized and baggied.
|
|
You can see the passenger's side head here.

|
Closeup of the valves.
|
|
Another..
|
|
Closeup of the cylinder - I'm not sure if that's corrosion or just gasket junk.
