Vibrations...

-89 318 & A500 & the engine has been out & put back in again at some time. So does that mean it's a cast crank then?
I can drive for about 5-10 minits before it starts & it's in the whole car, it's a rumbeling shaking vibrationbut nothing in the steeringwheel or brakes, it rolls good when put in neutral & when it has started it continues...
