<VV> serious problem with my turbo engine

[Ulli Dittmar]

Hi folks,

it started about 2 month ago. the engine was running worse and worser.
I went to a friend and we tested the compression. All cylinders show a reading of 10 except no. 5 (the right side, last cylinder view from back) only gives us a 2.1 reading.
I took off the head cover today and the inlet valve spring is more than lose, I can turn it around by hand and can even push it (compress it) by hand.
Since it is the first time I am working on a Vair engine I am really not sure what to do - please help - I am confused.
What can cause this problem and can it be a fallen/loose seat. The spring also is much longer than all the others.

Any help is appreciated

Regards
Ulli the Ba-Vair-ian
