I was recently changing my oil on my 88 FJ62 and noticed as I was refilling the oil that it began to leak out of the front one of these two holes. They are near the oil filter and I was able to eventually fill the oil up without it leaking. I noticed it only leaked when I would try to fill the oil up too fast and was wondering if there is supposed to be a plug there. I just recently bought this rig few months back and the seller never mention having a problem with the oil leaking.
