Yes, I did remove the tensioners, but I think the issue was that the Intermediate Shaft was not locked well enough. I tightened the set screws before removing the IMS cover but then when the cover was out the screws were loose, so it might has slipped while removing the cover.
Now the problem I have is that I can only find info on re-timing the earlier 996 engine, but I could not find anything for my engine '02 996 VarioCam Plus. I read some post stating that the procedure is different, but not explaining how to do it. maybe Porsche52 can jumped in!!!
Thanks for your input
