I recently acquired a 250sx, not running. the previous owner said its got a bad head. I got the thongs stripped down but am having trouble figuring out how to get the engine out of the frame and onto the bench. With this size engine there seems to be very little wiggle room. got all the mounts undone, just can't figure how to disengage the drive shaft and pull the motor out the right side. Anybody got a good trick for that?
