You should pull your top timing belt cover and make sure there is no oil on your timing belt. It could be cam seals, VVTi pulley seal, crank seal, valve cover gaskets, or something else. There is a lot in that area.

My money is on the intake cam gear. That vvti pulley will leak and splash onto the timing cover and leak around the edges. You can either replace the entire thing or order an aftermarket rebuild kit. There are some video online showing how to do it.

The cam seal would leak behind the rear timing gear cover and drip down not splash back up to the front of the timing belt cover. I've made that misdiagnoses before and I've seen it multiple times.

VVTi gear. just did mine. i actually used a toyota canister style oring and fixed my vvti gear. very simple to do if you are MECHANICALLY inclined. Search VVTI gear repair or buy one for a couple hundred bucks for a new gear at toyota or lexus dealer. replace all seals and you timing belt.

more than likely it's your cam seals. Just did a timing belt on mine yesterday (3.10.14) and the seals literally came out in 4 pieces each. Granted my leak was nowhere near that bad. My advice is to remove the top timing belt cover and inspect the belt to be sure there's no oil on it. No oil= cam seals.
oil= vvti cam pulley..buy a new one.
youtube search "Jeff's Garage" about the VVTi rebuild. In my opinion its not worth it. Just buy a new vvti set up. I believe it's 150

Hey mine like dat would it still be that cuz on his the oil droplets are not the same as mine. Mine drop from the oil pan but i dont think its thw oil pan since the wind would be able to push up dry tp the lower part of engine
