Instant engine knock
to be fair it would probably just burn off immediately
It would either be impossible to assemble or lose 90% of its efficiency in a few cycles after the paint goes away.
only the top is in the burning chamber. The paint will cause friction when the piston should roll veeeery smoothly over the crank and when moving upside down in the cylinder. There are plenty of engine failures in these areas even without paint.
i guess we’d need a sacrificial engine and some paint, but i imagine the combination of heat, chamical stress and friction would just strip it off.
The real problem would be getting them into the block.
Don’t do this.
You’re supposed to season pistons and rods like you would a cast iron fry pan. I like to use a combination of canola and beef tallow, but a 5W20 works in a pinch.
Remember kids, a happy piston is a varnished piston. Keep those oil rings in place, make sure they’re good and solid!
Can’t tell if serious or not…
Don’t listen to him. Wd40 and kitty litter is what engines love.
Along with bleach in the engine oil to keep it clean
Fool, bleach belongs in the coolant.
Go watch a few engine tear downs by I Do Cars, that will answer all questions, remove all doubts.
All I saw was Sauron

They had the knots in the wood displayed as eyes in both so I think this was intentional.
I thought this was the joke, but there’s another thread about BBQ sauce, so I’m not sure.

Be fine, as long as they don’t skimp on the waterproofing.
As a mechanic, make sure to use BBQ paint for heat resistance.
Nice try. You’re just trying to upsell, like those assholes who sold me the expensive blinker fluid when I found it much cheaper elsewhere.
As an engineer, do not paint the pistons at all. If the paint stays on it adds resistance and if it doesn’t then it gums up the engine.

Woosh.
You wouldn’t even be able to get the pistons in the cylinder with a layer of paint on them.
Not with that attitude! If it doesn’t fit get a bigger hammer!
As a non-mechanic that watches various channels working on vehicle sin various states of use and repair… It seems that half of vehicle work seems to require hammers, and the other half a hammer should never be near. And knowing the difference is a mystical art form.
Growing up I thought it was all giving as many uggas as you can dugga. I broke a lot of stuff learning a lot of it is only being as mean as you have to be. Except for suspension work. Suspension work requires pure hatred and a hammer.
Large vehicle suspension components scare the living hell out of me. Seen too many videos online.
Ha!
If you say something sarcastic you have to annotate it, such as with a /s, because no matter how stupid you think a take is there are people who unironically hold that opinion. It’s called “Poe’s Law”.
This is /shitposting, not /howtobuildanengine
Engineers, am I right? Lol
Well, I am also an engineer (I recovered) but ya, most engineers.
😆
Bro was just handling an edge case
What about /howtobuildathomasthetankengine are we there
Skill issue
Yeah, everyone. Listen up - we need to mark every joke so that everyone can laugh. Remember: the best jokes are the ones we have to explain.
laugh track
Wouldn’t that defeat the purpose of the joke if you had to explain it?
!Wait, wait, I’m joking! It’s a joke!! Stop rolling your eyes!<
I know you’re getting downvoted for being whooshed but I wanted to say I appreciate the explanation on why this is horrible. This is way out of my areas of expertise lol.
I work with engineers, and this is exactly how they are folks, trust me.
Why paint if you could wrap them instead, preserving the original paintwork
Make sure to sand them first with a rough grit or the paint won’t stick. You can also add sugar to your gas tank to make your sick piston paint job super sweet.
Use a pickaxe to add speed holes to your hood, and stick a flaming rag out of your gas cap and you’ve got the recipe for a sweet hot rod.
Well painting them black makes your car seem kinda sad. If you’d painted them red, that’d given you at least an extra 10-15 HP per piston.
You paint the outside, like big diesel manufacturers do. Red for speed, yellow for torque, blue for efficiency.
Found the Ork boy
No, paint 'em blue, they’ll be luckier.
The piston might feel blue and lose speed there. Better keep it old and gold.
You’ll need a lucite engine block to show off your shiny new pistons.
For guaranteed extra performance, get an apprentice machinist to mill Z3 vents on the tops of the pistons. Less aero drag means pistons reciprocate faster, faster pistons means more powah.
I just pour some steel Shot Peen into a oil filler after an an engine rebuild
