Are the 4.0 motors reliable and tire/lift ??

[They call me Pete]

I found a 96 RR with 140k on it. Should I be worried about the motor ? I know it all depends on maintenance but do they have a good track record ? Also can I put bigger tires on it without rubbing issues. I won't be off roading it hard but want to get rid of the grocery getter look. Can I put a 2" lift on it without lengthening anything ? Hopefully I can take this one home

i have a 00' 4.6 HSE and it has 90k on it and never had any trouble. knock on wood. i am putting a 2" rovetym coil on and will be running a 31.5" tire. my research basically concludes no rubbing. good luck.

I had a 4.0 in a '97 disco that went 170k with no major issues (had to replace the water pump). However, by about 165k it had developed a bottom end knock and some valvetrain noise. I am pretty certain the bottom end noise was an endplay issue, and the valve train noise, was likely due to the some cam lobes wearing. My wife drove that Rover and she really babied it, so between regular maintenance and her kind driving that 4.0 went a long ways. I had a spare motor and just didn't want to deal with putting it in, so I sold it with just over 170k on the clock. We owned it since it 76k on the odo and prior to that it had always been serviced at the dealer. So it had regular maintenance it's whole life. It never got hot and I think that is one thing that really extended it's life. It still ran pretty strong, even with the bottom end noise...
