Jeep Information

Hi all :-)

Does someone have an advice for the following symptom?

A light but clearly audible knocking (sounds like clicking on a computer mouse) appears if the engine is warm on idle rpm or if you ease off the accelerator and the rpm is decreasing. It varies with engine rpm. The engine got new head gaskets and new valves on cyl 5&6 about 1500 km ago. Oil new, quality and quantity is as it should be. Engine was build in 2002 and has a bit more than 200000 km on the clock. The specialist at the Engine Shop said the engine is in above standard conditions for his age and mileage and the light knocking is nothing to worry about, that would be quite common.

What is your opinion?

Many thanks in advance!
