I'm sure plenty of these things have hit 300k with varnish like that.

I had a 89 Camry with the 3S-FE. There was a oil seal under the timing cover somewhere that let go on me, dropped a lot of oil quick. I ended up selling the car, and I think the timing belt broke on the way home account getting oil fouled. I would have liked to keep the car, but it had too much rust. For whatever reason, the cooling fans were always running when the engine was on. Might have kept it running better, didn't get as hot.

Is it just me or are the front cam valve clearances way off? Shouldn't the lobes be shiny silver like the other cam?

I'm not sure--IIRC this is not a hydraulic lifter, but "mechanical" and thus the clearance it has means the base of the lobe shouldn't be getting contact, or minimal at that.
I suspect I need to give in and "run the valves" to see what they are at. Not sure I really want to as I might find some out of spec and then have to fix it! It's not hard work but I don't have a stack of shims to play musical shim with.

This engine is not sludged-up. It has some varnish in it, but this is perfectly normal for a car it's age and won't hurt anything.
