Problem with a BMW Z4 2.5L 2004 50k

Top end noisy, suspect noise due to contamination build-up in the hydraulic valve lifters.

The fault was cured by carrying out a 2 hour Forté Advanced Formula Motor Flush and adding Forté Top End Treatment to the new oil.

Thanks to Gerry at Evergreen Garage Crowfield Ltd in Ipswich, Suffolk.
