Land Rover Discovery and Range Rover Bosch 4.0L and 4.6L Engine Problem Repair

• 
  
  You may have heard that there are problems with the 1999-2002 Range Rover and the 1999-2004 Land Rover Discovery Bosch 4.0L and 4.6L engines. These engines are not all affected by the manufacturing problems but be careful when looking for one of these vehicles or one of the engine used in these Land Rovers. Have a professional check out the Rover before making a deal. Personally, I have been running a 2001 Disco for three years with no problem at all; this is my wife’s Rover. I thought many of you out there might be interested in our repair of these engines with the fault.  These are some pictures of the problem: this photo at the top left is what the engine looked like before removing the cylinder liners, no noticeable problem. We tested the engine and found that the second cylinder down had been leaking. The reports of micro fractures in the water jackets are a real problem. The repair for this is to replace the cylinder liners with the Top Hat style. This is a permanent repair. The first step is to cut out the old liners, this proved to not be the end of the problem. Once these liners were removed we could readily see that the engine block had too thin of a water jacket. The photo on the right shows what this looks like; the tan area is where it has collapsed causing a water leak inside the engine.This area was too bad to make the repairs. Two holes exist in this area and a track from where the water was leaking behind the collapsed liner goes all the way into the crankcase. Unfortunately because of this problem this engine cannot be used, so another one was found. The problem with this is that you can’t tell if a block will be useable until after cutting out the old liners. So after choosing another engine block we went forward with the project. It was looking OK and the new Top Hat liners were installed. Now I want to note here that a ceramic coating is injected into the water jackets to permanently seal them with the new liners. The photo on the bottom left shows the finished product. This engine will last much longer without any leaking. The photo below is of three engine blocks used in the project, the one on the left was a back up and shows what the original used engine cylinder looks like. The center engine block is the bad block with the cylinder liners removed and machined. The engine block on the right is the finished engine ready to go for many years of service. This is not an inexpensive repair, so much thought should be given to this repair before starting this project.
