My 406 with XU10 engine has developed it's first ever mechanical problem. One of the lifters is sometimes slow to prime and is very noisy.
Other than replacing it which is a fairly major task has anyone had experience with the various additive which are available? Does anyone use engine flush?
The oil has been changed every 10.000 km's since the car was new, so I doubt sludge is an issue. It has now done 335,000 km's.
Thanks
