I changed the oil on Sat. After filling my 2017 Yukon Xl 4x4 with 7 quarts I put the oil cap back on, drove to a level area ( 50 feet ) let the engine run to distribute the oil properly for my final recheck on the dips stick.
I took the oil cap off placed it on a rag above the fan on the fan shroud. I checked the oil it was low, so I went to get one more quart in the garage. When I got back to the vehicle the rag was next to the vehicle - assuming wind caused it to fly off, not thinking about the oil cap at that time I just picked up the rag.
I put in the oil in and went to put the cap on - NO CAP.
The cap was not under the vehicle, near the vehicle, then it must have fallen into the engine compartment. Nope, no obvious signs of the cap ( we all know the cap is not a little thing ) the cap can't fall into tight areas as it's too big.
OK the cap must be in the plastic "skid plate" under the engine. Took the "skid plate" down, no cap.
I searched Sat, Sun, and today NO CAP. The cap vanished in thin air.
It didn't roll anywhere as I searched a 100-foot area around the vehicle during the day and at night with flashlights. I had my wife look in the engine compartment with a fresh set of eyes, no luck.
I spent $150.00 on an inspection camera that they use to look behind walls with 3ft extension to look behind the engine between the firewall - NO CAP.
I started the engine expecting it to rattle loose - NO CAP.
OK, so maybe I carried the cap back to the garage, house etc. Nope searched everywhere I was - NO CAP
I just ordered a new cap, but for the life of me this is one for the book people, the cap vanished in this air.
I doubt anyone can give me advice or that it happened to them, but just in case if it did where did your cap end up if it did fall into the engine compartment. My concern is that by not finding it, it comes loose someday and goes through my fan, belts, radiator etc. as I'm doing 75mph down the road.
