while you’re in there its best to check your alternator and make sure no oil is on it from the leaks, my cam seal leaked like a waterfall and damaged my alternator.
I spent total of 3 days working my *** off to give my car second life. Not sure how guys on YouTube do the job in few hours... but took me 3 days including New Years to do repairs. The best part is the outcome - car runs after repairs were completed
Leaking valve cover gaskets was the right guess and with 163000 miles and no major preventive maintenance done in the past (original timing belt) it was time to change timing belt and all components.
While removing stuck valve cover on the right side, very last bolt snapped. It took me at least six hours to drill and extract what was left from this bolt without damaging the thread... I worked like a dentist
Because both valve covers were leaking... it took lots of time to clean dripping oil form the engine and parts. I painted valve covers and reinstalled them.
Two spark plugs were stuck. It was almost impossible to remove them as if someone hammered them in... I used WD40 and took my time but got them removed.
While changing timing belt I bumped in to lots of stuck bolts. To make job easier I went and purchased Stanley compressor and set of power tools just like they use in most auto repair shops. But the tool was not powerful to remove 22mm crank shaft pulley bolt. For that I used start bump method and it worked like a charm.
Then I changed oil. I use Mobil 1 5w-30 on all my cars. Changed coolant but left what was in the engine block because of bad access to drain plugs. I was told that they are located just above where exhaust pipe connects.
After everything was reassembled I only have few bolts left to connect few hose hangers and few small parts. It was very hard job and maybe it would of been easier if I had a garage available.
It was all done outside in windy 32f weather.
Here is my new Mitsuboshi timing belt installed:
After my initial start I heard some knocking noise. It scared crap out of me... but only in few minutes I discovered that noise was coming because dry engine was lubricating. In few minutes engine was running perfect. Withe new DENSO spark plugs and all parts that I cleaned with tooth brush my Lexus LS430 runs better than ever before. It never run as smooth and quiet and never had so much power.
Thank you guys for reading.
P.S. Since my native language is Lithuanian, I am sorry if I made 1000 mistakes in expressing myself. I decided to include starter bum video... but you have to put ear plugs while watching it because of the language used . I was tired after working non stop for over 28 hours...

Most excellent man! I don't envy you working outside in freezing temps doing that job, heck it's no fun on a nice balmy day.
Enjoy your car, you have earned it.

Mine was the oil pressure sensor
I changed my valve covers and still was losing about a quart of oil every month. I thought I was going crazy. Sensor would leak not much with car off but when I watched it with car on leaking all around where wiring harness is. This was a very hard leak to find but my car looked like the above pictures. But valve covers and oil pressure sensor was where mine leaked and after replacing know more leaks. Below are couple of extra pictures. Car has been solid 214k

Is it the part itself that leaks, or the area where the part is inserted? Is the part expensive?
As our cars age, I hear about parts failing that I haven't heard about failing before. I know about the oil level sensor leaking, but this is the first I've heard of the oil pressure sensor leaking.

yeah first time I have ran into this problem to. You’ll also see a small leak on the center driver side. I thought I didn’t do the driver side valve cover right so I did the driver side again. Then jacked car up on jack stands with bottom cover off to check for leaks. During this process I found the oil pressure sensor leaking. I kept wiping off oil and would not go away. I thought that people would want to know about it because I never seen this. My brother in law that works on cars told me he seen this happen on his IS also. BTW if you guys need help I used to work for Lexus
