think their was something in the road as it was complete flat tarmac
and yea it was the very mount, made a error in cutting a square angular line out of it, needs to be a curve to take the stress
maybe it gave way meaning the engine hit the floor or the sump did ? who knows, luckily the break wedged together so movement was only around 1CM
lucky ? probably
all good now tho, new braket has been subject to a correct strength and shock test
