I changed my oil and started the engine. After a few seconds, I heard a knocking sound and saw smoke. I turned off the engine and saw a puddle of fresh oil on the floor. The old filter gasket was still on the block, under the new gasket. I cleaned it up and refilled my oil. It took 5.5-6 quarts (normally a 5.1 quart change). I warmed up the engine and went for a drive. Once I deemed everything normal and the oil temp was high enough, I did some full throttle to 8k redline pulls. Everything was normal. I popped the hood and listened. No unusual sounds. I must have run the engine for 10 seconds, 15 max at 2k cold idle. I doubt any oil got into the head during that time, since it all escaped through the filter gasket. Can anybody tell me from experience that my engine is probably fine?

Why did you start it without oil?
You are probably just fine. I've personally seen cars driven out of a garage and into the street before they were shut off. A "mechanic" forgot to put oil in because he got distracted. The engine was run for at least 30 to 60 seconds without any appeared effects.
He started it with oil, but the old oil filter gasket stayed on the engine, so it all blew out.
You are probably ok if it was a matter of seconds.
Hi.
You are probably fine.
You are probably fine.
that stuff happens all the time in oil change shops, thats why someone is under the car at start up. heck a good friend of mine did an oil change but forgot to refill a car and ran it for 20 mins with no oil while doing a coolant flush. the car was fine but he lost his job. i keep telling him he needs to give up the left handed cigs but he wont listen.
anyway you are probably fine. always check your filers for gaskets when you pull them off

Running your engine dry no longer than that more than likely did no permanent damage,i wouldn't loose sleep over it.

Just think of it as a 2 stroke engine and forget about it.
2 strokes hardly get any oil and they run "somewhat" good.

I bet you won't make that mistake again.
the only damage is to your ego.
Remember, too, that it probably wasn't completely "dry". There was probably a thin film of oil on many parts, and I suspect that SOME oil would at least pump through, albeit at a lower pressure.
I concur with the others - you are probably just fine.

It happens all the time at quick lubes and even dealerships. Don't lose any sleep over it.
Thanks for the support everyone. I have never seen such quick replies. I have changed my oil many times and have never made this mistake. I am going to do my first UOA on this engine to make sure everything is okay.
That must have been a big puddle.
Knockingsound notgood. So the oil all leaked out via the OF gasket - means you had oil pressure/flow for some time. A few seconds....hmm...10 seconds, maybe 15....OK
What I'm really stuck on where did the smoke come from?

Save your money on the UOA, if you are getting it to check for damage. 10-15 seconds is nothing, remember there was oil in the engine when you started it up. The double gasket caused the oil to blow out. As others stated it has happened before in dealerships, repair shops, and quick lube places many times before. You had residual oil coating parts.

Exactly.
Not giving the engine enough time to get really hot without ANY oil is what saved you. I'm sure there must have been a small film of oil from the oil change still coating most metal, though not enough to protect you for long or where there was no oil(oil pressure being a big problem obviously)...
It definitely doesn't look like anything catastrophic happened. Same oil pressure and performance? If you haven't lost power or performance/no weird sounds since etc, then no damage will suddenly appear later. At worst you may have worn some of the metals slightly. Of course, it doesn't take long to heat up metal on metal at the speed and force engines are run under.
