Thread: No! the nut didn't go there

.

Hmmm mystery nuts....its like all those "extra bits" you get in an ikea flat pack!

Once when doing a major service (timing belt) on a vehicle of another make, I was somewhat distracted in the driveway and lost a bolt. Not to worry, it turned up 3 weeks later lodged in an intake valve. It had rattled around in the head until it had been sufficiently peened down to a size it would comfortably slide into the open valve. Thankfully the motor in question is a non-interference design, so no valve meets piston action.

I'm now like a scrub nurse in reverse. I count them out and I count them back in again.

And the bracket it was holding!

The only foreign object I've ever found in the engine bay, was a Mitsi mechanic's curved pick tool.

Should the filter be discoloured on the top like that?

"Bonus hardware" is the industry term for that. Seriously. When I worked at Holden's Engine Company in the 90s we'd get a few of those coming back regularly. Typically a disgruntled/bored/evil employee would drop a nut, bolt, similar down the intake and then bolt it all together. First time you gave it a decent fang the increased airflow would pull it into the engine and you'd have one unhappy customer...

Does make you wonder how it got there in your case. Got a snorkel? Maybe someone 'posted' it?

I recently bought a mid-sixties classic car with twin carbs. In each of them was an 1-1/4" bolt jammed sideways just above the venturi. Aircleaner attaching bolts. That could have gone badly.

Hmm, any funny noises in your Camry Mick?
