My Indy just did my 996 last week and we went through this. Everything at tdc. Cams have to be locked on bank 1-3. Crank lock tool needs to be inserted. 1-3 chain tensioner removed and ims chain tensioner removed. On 3 chain motors you also have to lock bank 4-6 cam (intake iirc) to keep it from moving with the slackness of the chain. You can then remove the ims but you have to note if there is any side movement if the ims shaft. If there is then you have to also take out the bank 4-6 tensioner (hence the locking of the cams on that bank as well). I will,try to have my Indy post tomorrow for you. I am sure that jfp can guide you better, but thought I would try to help as the 3chain motors are a bit more involved than the five chain motors.
