new to the forum, but owned and worked on many toyota 22r's. I once did a timing job (the easy way, as you all call it) on my 87 4runner and had the same problem. the leak ended up being the front main seal. there are little "fins" on the inside of the seal and one had a small rip in it, maybe I did it, maybe it was like that, who knows, but it leaked a fair amount of oil and flung it all over since it was behind the main pully. might give that seal another look, you will have to take off the oil pump again as i remember. hope that helps

for the record there is an even easier way to change that timing chain and guides if you all have not found. if you modify a wrench with a grinder and a torch you can do the whole thing with out taking off the timing cover at all! just the valve cover and oil pump, if you have done it you know it takes some steady hands, head lamp, and a few curse words as well but you dont run the risk of messing up the head gasket.
