Hi Martine,
Indeed a loud engine sound. If the valves are okay, perhaps the wrong size pistons, creating a piston clapping or slapping. But I suppose the wrong size pistons would create high oil consumption and low compression.
Concerning the rear windows, there are 2 options:
1) H-type seal where the windows sits in just like your front window.
2) Later (and also described like this in the build manual) is a bigger type window that is bonded on. On the edge of the glassfibre comes a U-type seal (or a S-type cut in half as the manual says), then a black stripe has to be painted on the window and then it's glued in with Sikaflex. The manual says to make a black edge by smearing sealant on the window. This is wrong and the reason why your windows are taped in. The UV light damages the Sikaflex (it becomes brown) and lets loose. So you have to make an edge with special etching primer. The best way is to go to a Glass fitter like Carglass or Autototaalglas and ask/buy a small amount of etching paint since it is expensive and you only need a bit. It's best to have the fitter bond the window in to prevent leakage afterwards.
Because with my first Gold I had to work on the streets on the windows and body edge and had to close the car every time, I had made perspex windows that just bolt in.

Margo van Vooren has now the glass windows fitted again. If you fancy these "racing style" windows you maybe can buy them from her.
