Troubleshooting Uncontrollable Acceleration in Cat 226b Skid Steer

Question:

Experiencing issues with your Cat 226b skid steer? Three times it has suddenly accelerated uncontrollably, with the foot pedal having no effect. On the latest occurrence, it even continued running for 10-15 seconds after turning the key off. Despite a recent tune-up and visual inspection of the engine compartment, the problem persists. Any suggestions or advice would be greatly valued.

I'm certain there will be many inquiries, but here are the first couple: Is it necessary to regularly add large amounts of oil to the engine? After stopping the engine when it ran uncontrollably last time, did you inspect the oil level before restarting to see if it was low?

If your car has a turbocharger, it's possible that the seals may be failing, causing oil to enter the intake system. In some cases, the engine may not shut off at all. In such a situation, it is imperative to block off the air intake immediately. This issue, if left unchecked, can lead to further mechanical problems.

The oil level showed a slight increase before and after, but within normal limits. It remains consistently unchanged between services. Is it possible that a malfunctioning injector caused this issue by remaining open? Upon inspection today, I observed a ticking sound coming from the head of a cylinder, leading me to believe that a valve may have been struck by the piston during high revving.
