4.0 - 4.6 good advice.

Hi,
A while back I rebuilt and stripped a few 4.0 and 4.6 V8s and saw many of the regular problems - I have just put my web site back up again now that I have returned from working in the Oil industry and some time www.ajmac.co.uk it has lots of the later Rover V8s.

Anyway, if you serious about keeping the car, I would strip your engine and get 'top hat liners' fitted, it's expensive (700ukp - ish) then rebuild your 4.6 internals back up inside it, you will have a bomb proof engine.
