Please tell me what you think:
I purchased a 2006 LX470 in January 2026. It had 258,300 miles on it and now, 9 months later, the odometer reads 261,100. This works out to about 3700 miles per year, but I am anticipating perhaps 5-6K per year for the next 20 years. (We kept our previous car for 24 years, so it's possible).
All maintenance is up to date, timing belt/water pump done in 2025 at 245,400 miles. The selling dealer noted the following in their inspection: seepage from front and rear crank seals, seepage from steering rack, seepage from valve covers. These were confirmed by our local highly qualified, premium priced repair shop, to the tune of $4800 to repair all three items. I'm sure I could get a somewhat lower price from another shop, but there are not a whole lot of them in our area (Olympic Peninsula in Washington State).
I have closely monitored the leak sites and fluid levels. Not a single drop of oil or power steering fluid has reached the carport floor. The fluid levels have not changed at all. Everything is working perfectly, no sounds from the steering, no anomalies at all.
I feel there is no point in spending a bunch of money chasing these issues until there is a real problem, such as power steering noise or significant oil or fluid loss. I plan to change engine oil every 6 months and follow the Lexus schedule of maintenance and inspection.
Would you agree that monitoring the situation is sufficient, or would it be prudent to rectify these issues before they worsen and possibly cause further damage down the road?
Thanks in advance for sharing your opinion/experiences.
 
I would wipe the areas down and inspect regularly so you can get an idea of how much fluid is leaking out and at what interval. For the valve covers, many have had success with just slightly tightening the cover bolts, careful not to over do it and snap them.
 
Valve covers are easy to do. At the same time, check your ignition coil packs, replace any cracked ones, and install OEM spark plugs.

The crank seals aren’t bad if it isn’t dripping. You won’t hurt anything by driving and monitoring. Steering rack threads abound. Check steering fluid level and read up on when you’ll need to change the rack. First I’d try a power steering fluid flush/fill.

Keep driving it and monitor the leaks.
 
If you check the torque on valve covers they are all likely loose and below torque value. Very normal not a big deal. Torque to correct value and call it a day.

Ignore the other seeps. Not gonna kill it as long as the overall levels are where they are supposed to be and it doesn't rapidly accelerated. Steering rack might be the first one that needs attention but it also might be years away.

Rest easy.
 
If the valve cover gaskets are original, re-tightening bolts will likely reduce most or all of that leak.

Full fluid exchange in the power steering system and add AT-205. Add AT-205 to engine oil.
 
You won't likely have a catastrophic failure with the weeping you describe, especially if you're not losing oil, not piling on miles, and you keep up with maintenance. Clean the engine every 6 months with degreaser and keep an eye on it. It's got nearly a quarter million miles, so I would not expect it to be perfectly tight.

On the other hand, you have a late 100 series, arguably the best made of the run, and you say you plan to keep it for a long time. That's worth investment, especially if it's a rust-free local rig. One of the country's best Land Cruiser specialists, Torfab, is located in Everett. Not exactly next door to PT, but might be worth getting to know them, planning for the long term, and maybe getting second estimate. Yours seems a bit high.
 
Refresh PCV system, valve and hoses. Excessive crank case pressure increases oil leaks
Re-torque head cover bolts to 54INCH-lbf.
Add AT-205 to oil, if leaks worsen.
Often when Timing belt done. Tech fails to seal threads of tensioner pulley bolt. This results in an oil weep, often thought to be crank seals.
BK2 cam seal may be weeping. Live with it, unit become a nuisance. Note: PVC & AT-205 may help somewhat here.
