The engine had very low mileage and was a converted VW industrial engine
The pictures show why this happened.......
This is how the camshaft looks when the "Muppets" installed an oil pump that doesn`t fit.
Here was a 3-bolt oilpump installed instead of a oilpump for a 4 rivet dished camshaft
The chips and chunks came into the oil circuit and that`s it.
