Disadvantages of the VW BZB engine
- This motor is prone to oil consumption only if the crankcase ventilation system is clogged.
- The timing chain here is quickly pulled out and can jump after parking in gear.
- Ignition coils do not serve here for long, usually they are destroyed by bad or old candles.
- The reason for floating engine speeds is most often in soot on the intake valves.
- Also, swirl flaps in the intake manifold get dirty and stick from soot.
