did you flush the block by removing the drain plugs. my 01 has hex head pipe plugs on each side, hiding behind the engine mounts. mine were sort of hard to get out, because i couldn't get either a socket or a wrench on them straight, and so they tried to round off. i eventually used my best vise grips to break them loose. so if you do this - treat them with penetrating oil beforehand, especially on a 94 that may have never had them off.
anyway, a lot of heavy sediment came out of mine.
