Subject: Timing chain replacement woes. Help!


Have the head off my '87 9000T ( blew the headgasket at 235,000 Ks) and I'm thinking maybe it's a good idea to renew the chain whilst I'm there. Problem is, the engine is still in the car, how the ##%&*!! do I get off the crankpulley and oilpump ETC so I can release the chain from the bottom of the engine? My Saab manual says to use a special tool which locks the flywheel, that's because they remove the engine from the car and then split off the tranny. I tried using the wheelbrakes with the trans in 4th gear, no good, gonna break something...and if I decide to replace the guides too, then I HAVE to get the blasted timing cover off. I know there is a chain available with a removable link, is this as good quality a chain as the original Saab chain, and will it run thru the guides OK? My chain was running noise-free, what is the reasonable life of this thing? What is the overall experience of people here, please advise.The local dealer is no help, mech says he's never seen one break. And speaking of "while I'm here" what is recommended for the head? How much will a valve job/seals and guides replacement going to cost moi? Should the head need planing? I drove about 20 kilometers on 3 cylinders, with a large chunk of headgasket material sticking out!
