Disadvantages of the Renault V4Y engine
- This unit does not tolerate bad fuel or operation with faulty spark plugs.
- For this reason, catalysts are destroyed, and their crumbs enter the engine cylinders.
- Another weak point is the oil channel gaskets under the front cover.
- The timing chain does not have a large resource and often needs to be replaced by 200,000 km.
- Like all aluminum motors, it does not like overheating, and the pump here is short-lived.
