I was out doing some testing and tuning the other night and all went wel. Until I came home and shut her down, after the ignition was off as the engine stopped I heard some sort nasty metallic banging. Made the same sound while cranking but went away once it lit off and was idleing. Everything sounds normal at idle and reving. Oil pressure is about 14 psi hot, right where it has always been. I'm thinking I tore up a motor/trans mount or the TC may have loosened up. Has anyone else had this happen?
