Chewed Up Bolt Found in Oil Pan
#47
^^^^ i was waiting for some one to pick up on that....instead one praised the magnetic drain plug for saving the motor. This HBO drama can shortened to ......drive it,sell it or fix it ....

If the bolt went through the oil filler tube hole and got side swiped by the crank carrier rotating components, it could have sheared off a small piece of aluminum perhaps?

What I'd be worrying about are the components that were bent but didn't break during whatever s**tshow caused the damage to the bolt.

If that came off, got chewed up and somehow got into the sump it would have been very noticeable. The fact that you discovered it by accident and not during a tear down following catastrophic engine failure leads me to believe it was dropped in during an oil change or somehow assembled with it in there. Best course of action may be to change the oil and continue driving as you have been.
Im assuming everything has seemed normal thus far.

If you have the service history, check if the oil fillertube has been changed.
It's secured with one m6x16 bolt.
When I changed mine, I noticed that it would be quite easy to drop the bolt in to the engine, if not being cautious.
It would go thru crankcase and end to the bottom of the oilpan. Worst case it would stop on the crankshaft carrier and fell thru when engine was running.

Again, thanks all who have offered comments or questions. From my 57 years of life experience, there is no such thing as a dumb question.

Possibly a bolt from chain sprocket that may have gotten caught in the area around the sprocket and consequently took a small chunk of aluminum before it got free and dropped into the pan. My sprocket bolts are hex bolts, yours are likely to be torx heads. I attached a picture of my chain sprocket so you can see the area i am talking about.

My vote would be to drive it until something happens. To figure out where that came from as you have pointed out will likely cost almost as much as putting a rebuilt motor in. Sure, you may screw it up so much that you no longer have a core, but it is very likely that that bolt has been there a LONG time with no ill effect.
What are the chances that the bolt ended up in the pan just a day or two before you found it. Almost zero I suspect. It's been hanging out there for a while, possibly from some previous work, possibly since the motor was built. Had you not gotten the magnetic drain plug, you would still not know that bolt and chunk of aluminum was there. You'd be driving the car happily until it met one of it's other famous modes of failure.

Suddenly, a neuron kicked off! He blinked, clearly startled by the unfamiliar sensation of thought, and asked, "whatcha doin?"
Thankfully, I am a man of limitless patience. A lesser boss would have merely pointed and yelled, "Get the f**k out!" I, on the other hand, was able to draw down deep from my reservoir of self-control, so I said "I'm making ice cream, you f**kwit. Now get the f**k out!"
Your sentiment is a beautiful one, but it's flawed. Stupid people only ask stupid questions.

One of my underlings wandered into my office yesterday wearing a Paula-Abdul's-got-the-nods-after-railing-oxy-all-night-long look in his dopey eyes. He paused, eyes lazily scanning the labels on the front of the server and the intermittent progress indicator of the Linux install. The flicking eyes were the only hint of intelligence, a single dot of sentient green on the otherwise unbroken gray expanse of bovine thickheadedness.
