Code po440,small leak in evap,.. And..

[flmont]

GM Gent's I have a few questions about my 02' 2.7 boxster,..1. that 440 code says small leak in the Evap system, can I assume that that's a fuel system leak of some sort.
2. lately after a gear change and clutch fully released I get a little hesitation,could that be a result of probably needing new chain guide pad's my last Deviation number's are 3.75 and 8.75,..and I do have that nasty startup noise,.very briefly but very noticeable.

Now for the curious question's,.is it impossible to install the 6sp trans from a 2000' Box S into my 2.7,..and can I also use the Mo30 suspension system from that same car,.?? I have the car with a blown engine,..or is it better to install another engine and put the car back on the road,.?? Thank's Very much for any info that you would share..Frank
