I finally got around to changing the oil and filter on my '65 Rambler that's equipped with the 196-cu-in OHV inline-six engine. The old oil filter was a NAPA 1049 without an anti-drainback valve The new filter is a NAPA 1258 equipped with an ADV. The old filter is about 5 inches tall; the new filter is about 4 inches tall.
When I removed the old oil filter, I found a tube -- about 4 inches long -- that protrudes from the oil-filter mount and extends into the oil filter when the filter is installed. There was room to accommodate the tube within the old 5-inch-tall filter, but the tube bottoms out inside the new 4-inch-tall filter. Thus, I am unable to install the new NAPA 1258 filter which "should" fit according to multiple sources.
Is it possible the tube on the filter mount exists to ensure oil doesn't drain from the filter when the engine isn't running? If that's the case, can I continue to use the taller NAPA 1049 filter that doesn't have an ADV?
