On my 93 TBI, I thought I had a breather hose problem or blowby problem, because oil was puddling up underneath it on the transmission case; and it wasn't coming from the valve cover gasket.
Turns out it was the head gasket leaking at the driver's rear corner. It used a quart every 1,000 miles, and it would puddle within a couple of days. After the head gasket blew and I fixed it, no more oil puddling, and consumption is over 2,200 miles a quart.
