Has 277,000 miles, shop diagnosed oil control replace as cure for catastrophic misfire thus putting the car into safe mode.
estimate was to replace timing belt, water pump, OCV $1200

Would replacing the OCV only correct the issue? and what is cost to replace OCV?

thanks

I cant tell exactly but at Toyota they are usually $150 range and could be installed yourself most of the time. The problem with an OCV failure with mileage that high is a good chance that there is engine sludge causing some VVT-I issues with oil flow. If it continually has issues related to VVT-I and it does exhibit engine sludge it would need a new engine more than likely.
