The odd thing about 216's is the "drain hose" actually is plumbed into the pressure galley that supplies oil to the dipper nozzles.
Oil almost never flows through the filter except at an idle when dipper nozzles bleed off the pressure at that area.
The fact is an oil filter on a 216 almost does nothing but look good.
Good info.
re. pressure to the filter. I know one time when I changed the element on my 216's bypass filter and didn't get the top tightened down enough, oil was squirting everywhere until I cranked it tight.
After shutdown it takes up to 20 minutes for the filter to drain down. I have to wait that long in order to get an accurate reading on the dipstick.
I often wonder if I could gain a psi or 2 by just removing the filter and capping the ports off....
