Yes, a full pressure system ( 1933-1954) with all bearing inserts. No external oil filter. A filtering patented system oil screen which is meant to be cleaned after a engine rebuild. Or about 100,000 miles. This filter was about a cup in size until 1941, then it was made larger and held about a quart of oil. Some people and dealers installed what is known as a bypass oil filter, but the factory said the engine didn't need it.
