I'm having difficulty getting at an oil filter on a 1987 B2000 pickup, the filter is on the side of the engine in the middle under the air cleaner assembly, I can reach the end of the filter from the top, but can't reach it from the bottom (no ramps yet). I was wondering if anyone has used one of those filter wrenches that fits on the end of the filter and you insert a socket wrench into the end to loosen it, are any good? I've only used the old type of wrench that fits around it.
