Thread: Indestructible, the saab B series engine...

Some here know we work on lots of non lr vehicles too, saab, volvo, subaru, etc etc. recently had a 9000 turbo saab turn up, fans going, smelling hot... Heater core leaking. Engine oil was fairly bubbling on the dipstick, hasn't been oil changed for 26,000 km, either. New heater core, flush filthy cooling system, full service and good as new. These engines, B202 (2 litre), B234t (2.3 litre)etc have some of the hardest valve seats and valves known to mankind, have had heads of them at 450k, and bear in mind these are turbocharged engines, and almost no valve recession, or guide wear. Bores usually are still as new, too. The volvo B series engines are also like this. Have seen many a neglected boiled dry tapping 2.3 240 series volvo here, revived it and sent on its merry way..

I would say they are the 4bd1 of european 4 cyl petrol engines! :-)

The valves don't fair too well when the timing chain breaks...

My son bought a sedan to fit the engine from his rolled 2.3 Aero.
