Disadvantages of the VW BZB engine
Only when the crankcase ventilation system is clogged is this motor vulnerable to oil consumption.
Here, the timing chain can jump after parking in gear and is swiftly removed.
Here, ignition coils don’t last long because old or defective candles usually destroy them.
The most common cause of floating engine speeds is soot on the intake valves.
Additionally, soot causes the swirl flaps in the intake manifold to become dirty and adhere.
