Is performance impacted?
Customer: replied 3 months ago.
Does not seem to be impacted...just noisey
Customer: replied 3 months ago.
Its not all the time...perhaps its a bit worse when the car has been stood for a day....its better after a good run for a day or so.
Expert:  Steve replied 3 months ago.
This is likely just the lifters tapping. It's a known issue. It does not impact engine durability or performance. You can try revving the engine in neutral to 4000 rpm for a few min, this may help a bit. Otherwise the lifters need to be replaced which is very expensive. Most people just deal with the annoyance. Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
