Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm going to be giving a mate a hand changing the tappets in his car, this will be on bank 2. The car has an intermittent knocking at idle but clears when the revs lift, I posted about this previously.
Is there any guides on this, Mainly for timing the car up and I'm also going to need something for locking the cams, and info would be much appreciated
996 manuals can be downloaded here ..

An idea of the tools needed but this is more than you need so just a suggestion for you to search ..

It depends on the year as to what kit you need .
Thanks for the links deMort, the car is a 1999 C4
Are we better going to Porsche for the lifters also is there anything else you would advise we do when we've got it timed up etc.
Thanks again
Tappet replacement is pretty straight forward .. not the easiest of jobs though .. be VERY carefull sealing the cam cover .. not too much sealent .. the grooves around the cam cover green bungs .. you DONT want sealent to block these .
I put the sealent on then use a ruler to spread it out and wipe off any excess sealent .
lifters .. anywhere you can get them , they are all the same as far as im aware .
Im not sure the year of your car .. if its vario cam plus then easy , just vario cam and you have to align the chain on the cams .. instructions though are on the download .
Road test the car .. 10 miles then inspect .. if a problem then you will have oil leaks at that point ... im thinking too much sealent and the green bungs get pushed out for this check .
EDIT ..
Read and understand the instructions BEFORE you do this job .
Second Edit .. align the chain as per instructions on the download . you have a chain linking the cams . .. if the slippers are worn then replace .
As Demort says, you'll definitely want to stick a new set of cam chain guide pads in.
The head ones get the most stick due to the size and profile of them.
Inexpensive and a total no-brainer while you're in there. They can start wearing from as early as 50k miles.
Here are mine after 65k.
