Ever gotten money back from a machine shop?

had a motor that i bought , wnt through a bunch of dizzys in . finally i pulledn it down to the cam and lifters . everything checked out in good shape putting the cam back with the new double rololer chain . i looked there was no bushing in the block for the intermedit shaft . so closer inspection shows signs of that shaft gear getting bashed around . new bushing new shaft and all back together again . runs way better now , lol . and no more timing issues , lol .
