Okay, have another positive update for everyone. Firstly, thank you again to everyone who gave suggestions and helped! This was some (unnecessary) PM that turned into quite the saga... Also thanks to @90WT for sending beer and moral support.
To summarize the story:
Snapped front driver side...
Believe I've found it! It's visible in the hole that the crankshaft position sensor goes in. This is looking up from the bottom, you can see part of the nut up against that cog in front of the timing gear. Happy I found it. As suggested, it's sitting on the upper oil pan! :censor:
Pulling that...
Anyone coming tonight have a crank pulley/bolt holder tool for the 1FZ? It seems I need to pull the crank bolt and figured I'd ask before making a tool. Thanks!
Yeah, I took the lower pan off and it unfortunately wasn’t there. Really hoped it was going to be taken there on a river of oil after draining it.
Have spent hours now trying to find it with a bore scope and magnets in the other pan from below too.
Alright... beginning to question whether it's better to spend more hours with the camera and/or magnet, or if it's time better spent tearing things apart. I had planned on doing oil pump gasket and distributor O-ring at some point, but upon closer inspection of that area I think the biggest oil...
Thanks @Kernal. I got a similar camera at Lowe's yesterday. Still haven't found that stupid nut.
Yesterday looked everywhere with the camera from the top side, and also from the bottom after pulling off the first oil pan (the easy one). Tried magnet fishing again from both top and bottom but...
Thanks @JoeCova. Really hope I don't need to take the pans off to get to this dang thing. I do have a large fishing magnet that might be able to drag it along the bottom of the pan too. Will report back tomorrow on any progress.
Yeah, exactly. Not something I'm willing to leave to chance either... too much potential for it to be in a bad spot. I didn't drain the oil yet since I thought it might shift it around. I'll do that in the morning since I got skunked fishing for it topside, though.
Will try to find diagrams...
That's an access point I haven't considered yet. New to working on the 1FZ-FE engine. Thank you!
Did you drop something in that same spot and/or have no luck fishing it out of the top also?
While doing a valve cover gasket job on the 1997 LX450 today, the last valve cover bolt snapped when removing it. Thankfully it's in the front corner on the driver's side so it's easy to get to. There was a bit of thread still sticking out, so I thought I could thread two nuts onto the top...
