[ROVERNET - UK] symptoms of a dropped cylinder liner

Do you know if top hat liners were used? If so they cannot drop. Dropped
liners are usually a result of a cracked block which also involves
coolant loss and steam cleaning effect on the cracked bore/piston. More
generally occurs on 4.6/4.0 RP38 Range Rovers with the increased bore
and thinner walls. Take the plugs out to see if any are unusually clean
before resorting to pressure testing the block.

Hi Netters,

I have a V8 3.5 litre that has been re-linered to 3.0 litres. 

The new engine has done 10,000 km.

It has developed a squeaky noise that I would put down to a fan felt or
a pulley bearing, except that it sounds as though it is coming from the
rear of the engine.

If it is a dropped liner, this will be one scrapped Rover!

Can netters please advise?

I will of course be visiting a mechanic asap!
