I found my borescope today and investigated into the spark plug holes of each cylinder, the front one may be hitting onto a valve as there is a silver/ligher circular area on top of the piston.
The rear one is just heavily carbonized, but no detectable contact. Here is a short video of.
Not sure what to do, the second hand motors I am looking at apparently have no history.
