I have a honda civic 2000 with a d16 engine believe is from a 99 civic si. Is turbo and i was driving 120 just for fun and it stalled on me i took it down to 80 and was driving all of the sudden saw white smoke through my mirror put it on neutral and when i was heading for the ignition it was already off. Also changed the valve cover gasket the ruber because it spit the oil through the back of the engine above the manifold. The car don't want to start it has little compression but it tries to start. Check timing belt everything is on point changed ECU's checked spark plugs for spark. Checked oil it didnt mixed and checked coolant also didnt mixed or lost it. Im not a 100% mechanic but all i can think of is blown piston but even though it would start but making a horible noise.
