1995-2002 Range Rover P38A
I have a 2003 4.4 with about 98k miles mostly highway. For the last 20k miles I have noticed a valve knock upon acceleration after the car is warmed up - about 15 minutes into driving. Is this just the quality of gas in Miami or is the car telling me it needs a valve job? I don’t notice any loss of power or smoke issues - just this crazy knocking upon harder acceleration. Any thoughts are appreciated.
