Have a 2004 RX330. What is the Torque/Tightening Order for the (9) Rear Valve Cover bolts? Any schematic out there?
-
Hey guys! Hoping someone can help me figure out what are these lights in the photo:
Q1: What is the name of the lamp pointed by my index finger, how does it turn on, and what bulb does it need?
Q2: What is the name of the lamp pointed by my little finger, how does it turn on, and what bulb does it need?
I can't get either to turn on and I'm not sure if there is even a bulb in there.
Thanks in advance.

Adding anecdote of a failed overtorquing
Thanks for confirming that there isn't any set tightening order. I just did a crisscross pattern with gradual tightening all around. I do want to note that the torque specs on that website are not accurate. Haynes 3MZ-FE manual shows 71 in-lbs for the both front and rear valve covers. Moreover, there was another gentleman who commented on a youtube video that he noted that the Toyota's 3MZ-FE shop manual showed 71 in-lbs also (however, I can only personally attest to the Haynes Manual which I own). In that DIY youtube video, the mechanic relied on the website you suggested and overtorqued the valve cover bolts to 9 ft-lbs (108 in-lbs), causing one of this bolts to break! So, I would highly suggest following more reputable sources like Toyota/Lexus service manuals and Chilton/Haynes Manuals.
