Is rev and hold the engine while in P bad for it?

Or is it a myth? Im talking rev and holding it on a hot engine. So many stories saying how you can crack a piston or cylender block by the engine heating up too quick. Or you can cause friction wear on the cylinder walls, piston rings, and pistons. Or it can cause excess gas to go into the exhaust and ignite in your catalitic converter. And when you rev, the engine doesn't get the same lubrication that it would if you were moving, is that true?

This is what i found

"Gas ignition in your exhaust melts the ceramic emission filter, which then makes the car run like having potatoes in the tailpipe. Believe it or not, even though the car isn't in gear, the gears still will turn, so if you rev it up, it'll cause gears to wear down."

Scary stuff

And im talking about revving when doing maintenance and revving to like 3000rpms and holding it for 5 mins straight. Not revving at your local mom and paps pizza joint trying to impress the girls. I remember one time I freaked out cause one of my old mechs reved it to 3000rpms for 5mins cause he was testing something and i wasnt happy.

Do you think that did damage? 3000rpms for 5-6mins?

Will it shorten the life span of your engine?

It was 3000rpms for 5mins straight then 5min break and 3000rpms again for another 2mins.

Do you ever think about going outside or doing other creative things with your time? Or do you really enjoy trolling this site that much?

I did that once. Turns out chicks don't get excited over a three cylinder Geo. I was so cool in school.

One of the wisest car-related statements I ever heard was from of all people, Tom and Ray Magliozzi on Car Talk, about 20+ years ago when they told less jokes.

In effect they said, no matter what you do, every engine only has so many rotations in it before it wears out. And that is so very obvious and so very true.

So every time you start the engine and run it, including just revving it for no reason such as this, you are using up some of those remaining rotations. And I guess that's bad in the abstract, to answer the OP's rather abstract query.
