Another engine repair brought to you by cylinder deactivation… everyone’s favorite fuel-saving mystery feature. 😂🔧
In theory, cylinder deactivation is supposed to help improve fuel economy by shutting down certain cylinders when they’re not needed.
In reality? We keep seeing engines come in with damaged lifters, worn camshafts, bent pushrods, and a repair bill that makes everyone wonder how much fuel we were actually saving here.
This one had some serious internal damage, and the parts tell the story pretty clearly. When these systems fail, they don’t always fail quietly.
At SDC Automotive, we’re not here to argue with the engineers… but we do spend a lot of time cleaning up after some of their “great ideas.” 😂
If your engine has a tick, misfire, rough running, or warning light, don’t ignore it. Catching it early can make a big difference.
