Check engine light illuminated and there was no power to the vehicle. At highway speeds there was a severe vibration in the steering wheel.

There was another incident where there was a puff of smoke and a lost of power down to 25 mph on the road. The engine had a #3 valve go through the piston and run up and down the crankshaft. The engine was replaced along with another injector system and fuel pump was added. Several weeks later, a high pressure oil line broke from the weld and spewed oil everywhere. The axle assembly and the transmission slave cylinder were replaced as well.
