Narrative:

Find the source and stop the leaks. On descent into ZZZ; base to final; we had an extremely strong odor of engine oil in the cockpit. It smelled like sour dirty socks. It was so intense; almost 'thick' if you will. We donned our masks; turned off the packs; opened the ram air valve; and landed as we were approaching the final approach fix. No passenger reported any smell. The aft flight attendant reported a short faint smell.
