OK. Well, it's the middle of the work day but I work from home...
I snuck out to the garage to peer in the intake ports with the dollar store borescope. It may be terrible quality but it still gets into places I can't with the phone.
So, the places where leakage is occurring aren't that hard to see. I guess the bigger question will be how my sleeving failed to seal them off. But again I think I can do a much btter job of that with the heads off...
