1999 Saab 9-5 1999 saab 9-5 se v6 turbo bad timing tensione

Hi i just bought a 1999 saab 9-5 se v6 turbo.The man i bought it from said he was at a red light and it just stopped,he thought it was a broken timing belt so this morn i removed the timing belt cover to find the timing belt tensioner was toast,bearings gone looked bad!After doing some research ive heard that if it was at idle the heads "might" be ok.Is there a way to check the valves without pulling the heads? If i just set timing and tried it could i hurt anything else?I know i still have to fish the bearings out of the oil pan too.Last thing i cant find a service manual for this car only for the 4 cyl 9-5.Any help sure would be great.Thanks![img:a9fed165bc]http://www.2carpros.com/forum/automotive_pictures/535744_CIMG0176_2.jpg[/img:a9fed165bc]
