I’ve put it all back together with the new pads. Car feels slightly different and the deviation is slightly better but still between -7, -8.
Timing does advance but very slowly. Looks like the variocam assembly is faulty. I tested the variocam on the bench with compressed are and 12v activating the solenoid. It worked as expected but obviously in the car. Doesn’t have enough pressure. I suspect my inner variocam green seals are done. If I recall I did see some green rubber in the filter on a previous oil change.
Anyone know now how the cheapest is for a variocam assembly ?

Yes came out like that. I’ve re-shaped it.
No O’rings at all. It feels a bit loose in its home. Are there meant to be O’rings ?
About to pull the cams out.

Thanks Ahsai. I’m going to pull the green plugs and check the physical timing today.
Im also not trusting of the Autel. Certainly when I activate bank 2 at idle the engine stumbles however the data shows
no movement in cam angle. This doesn’t make any sense to me as when I do the same on bank 1 it moves 25 degrees per the data...and makes the same change in engine note

Hi from Down Under (Aussie). In an attempt to ensure I can efficiently chase Kangaroos down the street and also avoid "drop bears" I conducted a health check on my 2000 2.7ltr 986. The results weren't so great....
Diag Tool: Autel AP200
Readings:
Camshaft Deviation Bank 1: -9.45 (best I saw was -8.3)
Camshaft Deviation Bank 2: No Reading available on my tool
Camshaft Actual Position Bank 1: Happily goes from 0 - 25 - 0 as the Variocam activates and deactivates
Camshaft Actual Position Bank 2: Starts around 0. Doesn't change on activation. Slowly goes up to 20 at max rpm(at Max rpm it should be 0ish)...not Solenoid activation affected
Fault Codes: No Fault Codes
Tests:
Bank 1 Solenoid Resistance: 13.7 Ohm
Bank 2 Solenoid Resistance: 15.2 Ohm
Bank 1 & 2 Sol Current Draw: 0.770A
Bank 1&2 Solenoid 12v at idle: Both Change engine note substantially
DME output to Bank 1 & 2: Both 13.06v on activation
12v direct to Bank 2: Nil effect to Actual Cam timing however clicking can be heard and engine note does change at idle. At rpm I can feel a difference
Disconnected Bank 1 & 2: Couldn't notice too much difference to power or delivery
I've changed one of the variocam pads on the right hand side of the engine(looking from the back of the car) My diag tool tells me that is bank 1....which has huge deviation for which it shouldn't. I do have a reasonable chain rattle at start up... always thought this was normal.
So......Do I actually have an issue? is my Autel scan tool leading me up the garden path ?? All physical tests point to all fine. Scan tool tells me other wise.
A little stumped, Help Please

Air Box Removal
in 986 Series (Boxster, Boxster S)
Posted · Edited by BoostDR
To add the airbox won’t come out with above instructions. I removed the 3 10mm bolts and split the airbox in half with a chisel at the join. Came out in 5 minutes and can be glued back together and used again if required.
also the lower bolt is accessible from the engine back. You can’t access it from the snorkel side
