No, it is a lean burn/lack of oil, etc .
I see this all the time and have very good success with my piston build/clearances.
I have proven specs for a few different ratio's and can bore any size needed.
Most use 8.5:1 between 93-95mm bore, but can go as large as 96mm(only as a last salvage attempt).
I try to keep the bore around 2.6L with the 8.5:1 pistons and high torque cam.
Makes for a dependable improvement/upgrade and leaves room (thickness)for future serviceing.

I should mention that I bought my Arias pistons through Jim and had him take care of the related machine shop work. The result is perfect success. Go that route vs. trial and error if you want it done right.
My engine was a Haflinger, just a scaled-down version of the Pinzgauer. I also own a Pinzgauer and have worked on it myself over the years.
