    I have a friend who has a 2002 F250 that has lost compression in No3 cylinder,the thought is that there is a hole in the piston as there is severe fuming and the sump oil has a high soot content.we're not sure if the engine has liners thereby making it easier to repair as the other option is a rebuilt replacement engine costing 20,000 dollars Australian.I would appreciate honest sensible answers please.

    If it is the 7.3 diesel it is a "wet sleeve" engine. The sleeve can be pressed out and a new one installed--not cheap, but makes it just like new.

    Never heard of a factory wet sleeve 7.3 They can be bored out and sleeves put in, but why waste the money. Go with a remanufactured engine. Sounds like a injector went south and as a result of prolong driving this way, the cylinder wall was washed of oil. The result is a galled piston skirt and cylinder wall.

    once you get it apart, and if it has a hole in the piston. Something caused it. That cylinder had to lean out getting really hot. If you just put a liner and new piston in it will do it again. Birdtracker

    Could be that the air filter was ineffective and the cylinders were trashed as a result. Any particulates bypassing the air filter will cause trouble over time. Save a buck on a filter and spend a few grand on an engine and turbo. If it's a turbo, look at the turbo impellers and see if there is any wear. That could be an indicator of abrasive dirt entering the cylinders. That will wipe out an engine in short order, along with tghe turbo. A new or remanufactured engine is usually the best route if there is internal damage or excessive wear. Either way, it isn't inexpensive.
