Sooo  my= thoughts.
 
Maybe #2 is going lean?
Clo= gged injector?
Maybe an air leak in the intake tube, also leaning= out the mixture?
What did the EGT show for that cylinder?
 
A bit of= a long shot, but you could have a spark plug with a cracked insulator caus= ing detonation. That would raise CHT= and Oil both..  Cirrus and Champion went back and forth recent= ly about cracked plugs causing total engine failure, but those were turbo'd.  Think what you want, = but I personally saw a cracked plug and a Cirrus with a hole in the piston.=   Just sayin  Champions positi= on on it can be found here:
 
You are correct though, could be a probe, and swapping would be the = quickest check that I can think of.
 
Hey! I just = noticed who this is. haha&nbs= p; Should have just emailed direct, oh well, already done.  Let me kno= w if I can help.
