If the motor had coolant in the oil and the motor had overheated I would recommned pulling the engine down completely. You may not have damaged the seals on the liners but the bearings could be wiped out. Coolant in the oil makes for a terrible lubricant. At the very least you just put more labor and a few more seals into the job. Better than doing half a job and having to tear it all down again because you didn't go deep enough the first time!
