This is the quick easy "fix" but is also an incorrect way to solve the problem. Fully constraining your parts is crucial in a complex assembly. It is a good practice to be practicing the right way to do things. Before teaching I worked in the CAD department for Parker Hannifin, and when modeling complex manifolds there was always a lot of part overlap with other assemblies. It was very common for another designer to take a complete assembly and remove individual components and replace them with customer requests. When constraints are done properly (using datum axis and planes when possible) this is a quick task. When done through the method you describe it makes other people's days more difficult.

To the OP, re-constrain the whole thing, if nothing else it is 15 minutes of good practice.
