Good luck with your repairs.

Did you have any symptoms of failing seals in the engine? Was there any difference after the replacement? I replaced mine in December with the Beisian double VANOS kit just for kicks (150,000 km) but did not notice any changes at all though my pistons were loose like your video shows and then tightened up with the new seals like your 'after' video.

Just did this with 97k I feel a difference in low range tq but after the motor gets heat soaked it's back to the same old slow 330.

Actually right after doing this and cleaning the icv and throttle body the car felt like an effin rocket, especially in 3rd then after a night of hard driving it's back to the same. I don't know if this is common or I messed something up but it was incredible the first ride I took. Felt way way faster

The noise of the loose pistons is gone and part throttle response improved.

Is your DISA Valve making the rattling noise?

Sorry, I should have stated that I had no symptoms or problems at all (read: no rattles). Based on recommendations on these boards I thought I'd replace the VANOS seals just for kicks and as an excuse to get a bit more intimate with my engine since I hadn't ever had to touch it before.
