Crankshaft front seal leak?

i did most of this job without a FSM. Ive been working on cars since 2008. I know my way around an engine. This was my first timing belt/water pump job. it took FOREVER to do. If you are going to attmept to do this on your own i would highly suggest getting the FSM. I had to guess or research on stuff all the time and it was a giant pita!
My oil pump housing was leaking BADLY. thats where all my oil was coming from. redid the crank and cam seals along with dropping lower pan, and prying down as best i could to remove the oil pump without dropping upper pan (didnt have way to support engine from top at the time).
It was one hell of a learning experience and a much deeper appreciation for my car. before i did the job it was CLEARLY pushing out a quart a minute out of that hole in the bottom timing cover. it was FUBAR. now? not a drop of oil or coolant to be found anywhere.

My 98 GS with the VVTi engine seems to now be leaking from this area. I have successfully already replaced Cam Seals,(via cam removal and dissassembly), valve cover/ spark tube seals and front crank/pump seal.
However I now suspect the Oil Pump leak as I am getting a constant slow drip after warmup from the lower timing cover behind the crank pulley. Also I am hearing some very faint rod noise at idle,that points to insufficient oil pressure, presumably as oils is bypasssing the Oil Pump O-Ring as on its way to the Oil Main galley.
HELLO Aeok18109, I IM'd you about this, would you be so kind to text or call me back at your convenience, 6787709017, would really appreciate it. Thanks! David

So I have since replaced the front crank and 2 front cam seals. I was about to take it for a drive and noticed fresh oil leaked on the ground below.
I chucked a bottled of fluorescent dye in the oil but it didn't work that well. As far as I can tell it looks to be the RH cam seal leaking. I'm hoping I haven't pinched it putting it in or not seated it correctly
. Take a look at the attached pics of it running and not running. (the pics are looking down behind the cam pulley)
Pretty sure there shouldn't be a bead of oil visible outside the seal

Oh, BTW... Did you have any trouble getting the (not crank pulley) timing belt pulley off ? As I have no puller...

Not quite. By 'crank pulley' he is referring to the harmonic balancer. He's asking if the crank timing sprocket can be removed without a puller. You say no, I say yes. The balancer and sprocket both slide off with your hand. The sprocket sometimes requires a slight nudge from two screwdrivers prying at the back at the VERY MOST. No puller required.

The usual way seems to be to put a screw into it and pry that out: https://www.clublexus.com/forums/ls-...ml#post9848400 (edit: just noticed that you were the one who asked the question in the linked thread, oops)
There are also apparently various tools you can use, including seal pullers and a slide hammer.
I don't have a drill or any of those tools, so I just got it out by pulling on it from the inside edge using a paint can opener, which Ace Hardware gives away for free.
