Hello, I'm new to the 9000s. I picked up a nice but beaten up 1988 9000 turbo and I was going through it tonight. The previous owner had a family friend do a head gasket job done on it and they had left the distributor untightened, so the engine ran on three cylinders. They also left the head cover bolts hand tight.
I adjusted the timing to ear but the engine still didn't run smoothly. Fearing the worst, I took off the valve cover and found that the timing marks on the cams were at the 10 o'clock position when the engine was at TDC. Frankly I'm amazed the engine ran at all. Shouldn't the valve be toast?
I'm new to the 9000s but this engine, at least as far as the ignition timing parts go, is much like the 900 era 16 valve engines. And I don't have any sort of shop manual for this car. But I have many years of taking apart and servicing 16v engines in SAAB 900s. I want to make sure I correctly set the timing of the head to the TDC. Measure twice, cut once sort of thing.
On the transmission I saw two notches which look like iron sights on a rifle. Is this the timing mark?
I want to get the TDC on the cams and the flywheel to be dead on. Does it work the same as it does on 900 era 16 valve engines? Where you line it the cams with the hash marks on the caps at the far end of the head?
Based on these rookie mistakes I've found so far, I'm concerned that they didn't tighten everything like it should be. I don't want this thing to come apart on the road. Aside from the head bolts, and the intake and exhaust bolts, what else should I check?
Would it be a good thing if I loosened the head bolts and tightened them like the 900 shop manual suggests? (in the three stages)
