[Pseudotropheus]

As I do "Engines" this quarter in school. I decided to bring the Beetle in the shop and run a ton of tests.
I am going through about 1 qt of oil every 400-500 miles.

Yet, its not shooting out the tail end. I dont have a leak or any signs of dripping. I ran a compression test on all cylinders. Getting about 105-110 PSI on 1 crank, and as high as 190-200 PSI on 4 cranks.

I decided to do a Cylinder leakage test. I am running about 25%to 31%. There is supposed to be about 20% leakage. So its a little higher, however, it is no where near the danger zone.

With the slightly higher readings I was thinking Piston Rings. However, I would venture to guess that these readings, should not be a cause for concern.

I did run a Bore scope on all cylinders, and noticed a very excessive amount of "carbon" build up on the walls and atop of the pistons. I am gonna run some B&G 44K on it with some "Supreme-o" gasoline. See if this burns it away.

Still, how can I be chewing up this much oil. This baffles me... I cannot figure out where it is going...
