DIY - Cam Chain and Tensioner Guide
whitemoredooor:
Ok folks, just stripped down the cam chain cover to find a tenstioner in bits ! also someone has already had a go at this job and the cam adjuster bolt has a very rounded head and i cant get anything on it to remove, can anyone help at all as the tensioner fell to bits and i cant get this back in without removing adjuster, tensioner was glued together !!! whoever was in this before me needs a slap !

Depending on how mangeled the bolt head is... youll either have to try and use the OEM tool. or drill the bolt out

Got the bolt out with the use of a drill, when re-assembling i needed to rotate the intake cam very slightly, when you did it as i notice on your post that your intake cam was in a different position from when you started, did you have to make any adjustment prior to finishing the job? i have a very slight difference between the marks i made on the cams albeit very little.
Thanks in advance

Is it all back together @whitemoredooor ?
You can check your timing via VCDS:
Block 91 or in advanced measuring blocks 91-3 & 91-4. These are camshaft adjustment REQUESTED and camshaft adjustment ACTUAL
if AXX - you should see 24KW requested, and +/- 1kw of the requested for actual so 23-25 kw
If BWA and some others (needs checking) - you should see 28KW requested, and +/- 1kw of the requested for actual so 27-29 kw

Providing both cams have rotated by the same amount then it should be fine.
If in doubt turn the engine over twice by hand with a long ratchet on the crank bolt.
