I have a very nice 2001 4.6 Rangie. It has never been very fast but drives very smoothly, quietly and sedately.
Having had various Rover engined TVRs with loads more power I am wondering if like TVRs is camshaft wear a problem with these engines? My experience is that 70–100 K miles is about the limit for a camshaft. Wear is hard to detect due to the hydraulic tappets so my question is: is this a common occurrence with the 4.0 –4.6 L engines?
Symptoms: when you plant your right foot, the car accelerates but seems very slightly hesitant and very slow for the revs to rise. On my private airfield, I clocked a maximum of 100 miles an hour and that took a while to achieve!
Car has done a genuine 80K
Of course it could be something else but I am at a loss as to what it could be.
Any ideas would be great!
