Hello everyone!

Doing an inspection to my 3300 Jabiru Engine, with 426h, I have seen soot in the zone, between the intake of the manifold to the cylinder number 3 and the exhaust pipe outlet of cylinder number 5. I checked the bolts but it seems to be properly tightened. 

I checked the interior of the cylinders with an endoscope but they look normal. 

Could anyone tell me any idea of the cause? 

I have pictures but I don't know the way to upload them here. 

I'll appreciate any help.

The first thing I would do is to remove the exhaust pipe and check for signs of leaking on the sealing faces.
