Gary - K7GLD said:A given filter can only absorb and hold just so much crud - and when that capacity is reached, it might clog, or simply start to "channel" and begin to allow contaminated oil to pass on thru.
On my engine, down low on the block just above the pan flange, there are some openings that are blocked off with caps resembling freeze plugs. Some guys have reported removing one of those plugs - apparently used as dipstick openings on some applications - and using them as an oil return.
thats another way to do it, just use the right one!!!
