I am pleased to report that we have now completed the re-trimming of your E Type and installed the new canvas convertible top.

 |
 |
Lots of progress in the CJ trim room.

re-trimmed |

Both seat backs and headrest have now been
trimmed, seat bottoms in process |
Over the next few weeks we will be installing a complete Suffolk & Turley interior kit into our 74 roadster project.
 |
 |
| Original interior trim is in poor condition
and will be replaced |
|
 |
 |
| Dash top and sun visors will also be
replaced |
Convertible top frame removed, stripping
the covering from the rear bulkhead |

We now have your engine rebuild well underway and have already found several serious issues. One of the cylinder heads had some minor corrosion and two separate cracks, and the second cylinder head had some very significant corrosion on the deck surface. There are areas of the engine block deck that have been damaged when someone has attempted to force the head off by wedging something (chisel, screw driver, etc) between the seized head and the block.
As a result of all this damage, both heads, and the engine block itself, will be spending some time in the Coachworks for weld repairs, although we are confident that we can save all the damaged components.

I am very pleased to have this exciting project underway! Last week we performed a compression and leak down test on your engine and recorded virtually zero compression in cylinder B4. Further investigation soon revealed significant shrapnel within that cylinder, and impact damage to the top of the piston. In the short video clip below, you can actually see debris wedged between the piston rings and the cylinder wall. The shiny areas on top of the piston are where something has broken loose and impacted the piston.

Video shows damage and debris in cylinder B4 - major surgery required |
