In october 2019 my car needed to have extensive work done on its timing chains, variable valve timing solenoids, intake variable engine variable timing solenoid, variable valve timing sprocket, heated oxygen sensor, timing cover gasket set, valve cover gasket set, iridium spark plugs, water pump, engine oil filters, synthetic dexos motor oil, coolant. Then in july 2020 the timing chains collapsed on me while I was on my way home from work. The entire engine had to be replaced.
