Re: 1994 Explorer with engine knocking?
Very possibly you are hearing lifter "tap/tick". One of the reasons they do that is from a low oil level. With the hood open, it should sound like it's coming from the top of the engine.
HOWEVER, there is a much more ominous sound that comes from the bottom of the engine. A true "knocking" sound could be a bearing that's seriously considering hari-kari. If you're sure it's coming from the top of the engine, an oil change (possibly a lifter adjustment) should fix it. Otherwise, BEWARE!  n:

Once possiblity. Just a guess. Listen closely to the Idler pulley for the serpintine belt. I have heard that the bearing goes out on these and it sounds like a knocking sound. How many miles on this one?
