Rob,

 

Sorry this has taken so long to get back to = you.

 

My #5 cylinder does not have a crack!  It was = the baffling vibrating on the forward part of the barrel fins that “made” = fine aluminum dust that looked just like exhaust residue.

My engine roughness during leaning was due to clogged injector/s.
