I have bought two used Saabs, an 87 900S 16V and my 87 9000S. The pre-buy inspection showed no more than a 5 psi difference between cylinders. While 1 & 2 are consistent, that 15 psi jump to 145 in 3 & 4 is cause for concern. Time to check the valves and head gasket....How many miles on the car and does it use or burn any oil? Questions that should be answered before you buy, if you buy. Ken Washington 87 9000S 87 900S 83 900T
