Took my cam gears off and to my surprise they did not wear evenly . About 1/2 of each gear
Still have some coating on them and other half showing bad wear. I know PO had to deal with tb jumping a few teeth and bending a few valves. Heads were done ,quality of work is questionable ? Could camshaft be bend ? Will post pictures next

Because they are made of soft alloy with an uneven spray on coating.
That is why Porsche changes the design.
