I just tore down a FI 2 Liter Bus engine with 10kmiles on it.
Turned out to have the piston rings installed the wrong way arond on one
piston. Happend to be Cofap. Do you know how much work it is to do this
in a Bus? This really shouldn't be necesary. Didn't use any oil though,
developed only a low compression.
