Disadvantages of the Saab B234R engine
- This is a very reliable motor, most breakdowns occur at high mileage.
- The block of balancers delivers the bulk of the trouble, many simply remove it.
- If the spark plugs are changed infrequently, the ignition cassette may burn out.
- Timing chain stretching or oil pump wear occurs only after 250,000 km.
- Rare cases of engine failure due to unscrewed connecting rod caps were recorded.
