I’ve had the car for a few months now, haven’t had any issues other than recently. The service engine soon light came on not too long ago throwing me P0300 and P0021, random or multiple misfire and camshaft position actuator respectively. Yesterday, I noticed a lot of white smoke, as I drove home the smoke intensified and eventually I lost power at the gas I was about 100 yards from home after traveling a few miles. Any pressure on the pedal gave a “ratatatata” noise. Power steering went out, battery and oil light came on.

Ended up finding a broken connection on a coolant hose that connected to the firewall, fixed the hose and refilled the antifreeze, it seemed to have lost all of it. I suppose that explains the smoke, but now when we go to start the car it cranks but not start. The noise is that of a constant “whirr.” Read the codes again and was thrown the same as before, P0300 and P0021, but also P1217 level 3, engine coolant over temp.

Any ideas would be great, thank you

 

Pull all your spark plugs, if any are wet you cooked the engine. If they still look ok then do a compression test and a leakdown test to make sure you didn't warp the heads.

If it pegged on the high mark of the temp gauge you probably cooked it.
