The easy way I find for the sake of a hour is to R & I head first. It can be done without but the h/gsk is normally damaged on fitment of the timing cover.
R & I all ancillaries from the timing cover.R & I Timing cover. The layout is quite straight forward as you look at it. Note on the balance shaft bearings there is a I & E Inlet and Exhaust.Make sure the Inlet on the gear lines up with the I and the Exhaust with the E. Ideally change the Timing chain ( one piece ) at the same time and the guides and tensioner.
Change the gears on the balance shafts and the idler + tensioner.
Pay attention to the crankshaft gear as this can round off which may have caused the chain to slip.
I will post a diagram of the layout and the part no:- etc if you can wait a day.
The cost from a dealer would be with about 8hrs labour £1500-2000 Inc of parts + vat.
There are many good Saab specialist around the area/country that would help you with advice, and do it for less.
I would say if you have the confidence , do it. All its going to cost you is the parts + your weekend.
Thanks for the advice ScottD, a layout drawing and part numbers would be swell. Not sure if I will attempt it myself but as they say in Dr. Pepper ad. "what's the worst that can happen?". No answers needed thankyou!
I don't know where you are in the West Midlands but I've just had my timing chains + rest done, I can recommend a specialist in Leicester and have the name of someone in Rugby. I paid £450 ish to get it done by a specialist, and I think it is money well spent.
Looks like a piglet of a job to me, if it takes someone who knows what he is doing 7hrs how long is it going to take you ?
