If the timing jump do you need a new motor?

PLEASE list the engine size when asking about an engine problem.

The engines used in this model use a timing chain so it's uncommon for them to jump time. The engines are not listed as "interference" engines. If they were, incorrect camshaft timing results in bent valves and the need for a valve job. Replacing the entire engine is way overkill.
