I was replacing my PCV valve and noticed there is a missing bolt on the valve cover, attached is a picture of it. I am not able to find it anywhere, only finding bolts cylinder head.

I figured out how to fix this by removing the entire assembly with the AFM attached off the car. I assembled it outside the car very easily and just reinstalled the entire unit.

So today I replaced the air filter on my newly bought ls400. It was extremely dirty and seemed like it hadn’t been changed in years. When I went to reinstall the airbox, I could not figure out how to seal it up against the other half of the airbox. No matter how I’d position it, the clamp would not wrap around the entirety of the airbox. I also don’t understand how this clamp is supposed to latch, as moving the action doesn’t seem to change any tension. There are also some zip ties temporarily holding the side of the airbox housing which has a missing bolt, any info on that part number would be very helpful.

I just bought a 93 Ls 400 a few days ago. The owner says he could never figure out how to keep the ac from shutting off after ~3 seconds of being on. He claimed the compressor was recently replaced and obviously freshly recharged, but it still would not stay on. I also notice a whine coming from the glove box area, which is where I believe the servos are located. After running the AC diagnostic the only code that came back was 33 which is “Open in air mix damper position sensor circuit. Or, open or short in air mix servomotor circuit. Or, air mix servomotor locked." I am not entirely sure what this means even after searching this and other forums. What I’ve concluded so far is it could either be; a bad relay, a ground connection that needs to be cleaned, a leak in the AC lines causing the compressor to lock up due to lack of refrigerant, a faulty servo, or a bad compressor (though I don’t think the previous owner was lying about replacing it). I don’t really know where to begin. I’m not sure how to access the servos behind the glove box, or even diagnose what’s wrong with them. I’m not sure where the ground connections or relays I’m looking for are located either. Any help would be greatly appreciated. I want an operational nut chiller, man.
