A Toyota engine one of my employees assembled back in the late 1970's had an improperly packed set of piston rings in the overhaul kit. The oil rings were .75 MM smaller diameter than the compression rings. It burned massive amounts of oil from day one. He had neglected to notice that the pistons would drop into the cylinders past the oil rings without using a ring compressor. The guy had moved on to another job before we discovered the cause for the problem, so I ended up redoing the engine rebuild for free!
