turbo woes

[serendipity123]

ok i have turbo problems.

the two parts of the turbo appear to be loose, if you look at the youutube videos you can see the intake is loose and not connected to the exhurst side tightly, this is also letting gas'es escape from the join.

now i've taken it off and it looks like its a twist fit ?
