are any of these small cracks or micro-fractures an issue for reliability if I use this cover? or should it not have any cracks? I engraved a shit ton on it and then cleaned it up a bit and found these...…..I need to take my old cover off to check my clutch anyway for it having trouble finding neutral when engine is hot. SO I thought I could put the new cover on after all that. Is the engraving too deep? I really want to know if I can use this or not, I can take more pictures.
