This is a new engine (IO-360 parallel valve, standard compression, vetterman exhaust) put together by Aero Sport Power (65 hours so far). I have noticed some seepage on the number 2 cylinder through 1) the hole where EGT probe is installed and 2) The exhaust joint downstream that exhaust pipe assembly.
The stuff is almost semi-solid / rubbery and it took a little bit of effort to clean it up with a screw driver.
Checked the compression on the engine on that cylinder and its 79/80. Spark plugs looked clean. Oil consumption is pretty stable: one qt every 15-20 hours.
Here are some photos:
This is the EGT probe location with the seepage (cyl 2):
This is the exhaust joint downstream the exhaust pipe (cyl 2):
This is how the seepage manifests on the interior of the cowl:
All this accumulation is over 27 hours of tach time.
Any ideas / suggestions?
