If you've been around the SAAB community for any length of time, you have heard that the V6 in the NG900 (1994-98 model) models was to be avoided like the plague. Not having owned or ever driven one, I always wondered what the deal was. Why was the engine problematic? I found the answer at www.thesaabsite.com in their overview of the NG900.
V6 Engine: The 2.5 liter engine was available from 1994-97. Contrary to what some may think the engine itself was an excellent engine. The real problem with the engine was the pulley configuration for the timing area. The timing cover seal would get pulled into the belt area and cause the engine to jump time. Because the engine is an interference engine the valves would get bent and in some cases the ring lands would get crushed meaning the engine would need to be replaced because you could never get it to stop smoking after a rebuild. When a problem occurs with this V6 engine we highly recommend replacing the 2.5 liter engine with a 3.2 Opel engine that we offer. The timing area pulley configuration is much better and makes for a much more reliable V6.

As GI Joe said quite often, "Knowing is half the battle." He was right.
