Problem with a VAUXHALL ASTRA 1.4 16v Twinport 2006 89k

Excessive noise from hydraulic valve lifters and timing chain noisy. Suspect fault due to heavily contaminated oil from lack of servicing.

The fault was cured by adding Forté New Generation Engine Flush and flushing the engine for 2 ½ hours and adding Forté Top End Treatment and Forté Oil System Protector to the new oil.

The vehicle was taken on an extended road test, the engine noise had gone and the customer was very impressed with the results.
