Too quiet here ....

I guess to my boss "comp cams suck ****" is controversial, he actually took it personally because I asked him since we've had to rebuild 3 engines in 12 months because of flat cams, why do you keep using them? And before he answered I said you can atleast measure the f'n lobes to make sure they aren't machined incorrect. He turned red and got quite lol.
I'm a machinist not the assembly guy by the way
