HB wobble + minor timing cover seep - 1FZ-FE. How worried?

Looks like you got the oil pump cover O-ring installed, any trouble with that?

Is that an OEM harmonic balancer?

Old screws came out with no fight at all, using the JIS bit. Fit like a glove, having the right tools really does make a difference. Added a little purple Loctite to each on reinstall and cleaned up the surrounding area while I was in there. Also, shoutout to the Cruiser Patch fan wrench tool.

And yes, OEM harmonic balancer from Bell Lexus.

While everything was apart, I did a test fit of the 150A alternator with the Landtank bracket, and it dropped right in. Also swapped the idler pulley. Debating swapping the A/C clutch assembly while it's all this accessible to freshen it up.

What did the old harmonic balancer look like?
Any cracks visible?

Another victory, got the AC clutch assembly swapped out tonight.

Finished! Everything is smoother and much quieter, but hard to tell because the iPhone mic seems to pickup anything and everything.

Nice work. Really looks clean; which is a nice way to relaunch the beast.
Happy trails!
