Dropped oil filler cap into engine bay, any ideas?

[JakeHagg25]

So the other day I was replacing my fuel injectors (already had two fail on me at 40k miles so I decided to do the rest) and in the process I had to take the oil fill cap off. Unfortunately for me when I took it off it fell and I didn't get a chance to see where it fell into. It never hit the ground and I quite literally spent an hour looking to no avail.

So now I turn to you all, does anyone have any suggestions for where it may have gotten stuck? I went so far as driving my truck up and down the driveway to maybe knock it loose but no dice.

If just get a replacement and leave the other one. It’ll turn up or fall out on the road. I had a similar thing happen to me with a 15mm socket. I never saw it again.

Get a flashlight and start looking. Record video on your phone and wave it around all over slow and watch the video on a larger monitor and see if you can find it.

I found 2 oil caps lost in our work truck engine bay when I had to replace the AC compressor. If they don't fall out they stay put.

At least with a socket you can go magnet fishing.

I’d worry it would hit like the fan belt and cause an issue

Turn the truck upside down and shake it.

Drain the oil 1st though

Do you think an endoscope would help? Amazon shows multiple at less than $100. Might come in handy for other projects too.

Turn on your flash on the phone and just take video slowly and go around it. Tape it to a yard stick if you need to get in deep. Watch it on a pc and you'll find it if it is in there. I have an endoscope and it excels at getting a view in tiny things ( like inside body parts, pipes and tires ). It's not a good camera. any phone will blow them all away in clarity, if the phone can fit.
