We have discovered a flaw in a key component of the engine whilst rebuilding the engine of our SS100.

The Distance Piece is allocated near the front ofย crankshaft and is one of the intricate pieces that the oil seal runs on. At some point in its life this particular piece has been machined.

This is not an uncommon task to perform, especially due to the rarity of the part but unfortunately, on this occasion, it has been machined too much. This has created an irreversible problem.

The lip at the top of these images is where the issue lies. The lip shows the original size of the distance piece and on a perfect part this lip should not be there at all.

With the piece turned over you can see the lip at the bottom now.

We are currently on the look out for a new Distance Piece which will not be an easy task. This piece is no longer manufactured and therefore suppliers have no stock availability.

Over our many years of working on or with classic Jaguars we have some very useful contacts in the industry that we are hoping can help us with our quest to find the missing piece to our puzzle.
