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!

[–] rbos@lemmy.ca 28 points 3 weeks ago (2 children)

Can't tell if serious or not...

[–] MintyFresh@lemmy.world 20 points 3 weeks ago (1 children)

Don't listen to him. Wd40 and kitty litter is what engines love.

[–] ForgottenUsername@lemmy.world 7 points 3 weeks ago (1 children)

Along with bleach in the engine oil to keep it clean

[–] smuuthbrane@sh.itjust.works 4 points 3 weeks ago

Fool, bleach belongs in the coolant.

[–] smuuthbrane@sh.itjust.works 3 points 3 weeks ago

Go watch a few engine tear downs by I Do Cars, that will answer all questions, remove all doubts.

I thought this was the joke, but there’s another thread about BBQ sauce, so I’m not sure.

[–] realitista@lemmus.org 9 points 3 weeks ago

They had the knots in the wood displayed as eyes in both so I think this was intentional.

[–] Lemmyoutofhere@lemmy.ca 65 points 3 weeks ago (2 children)

As a mechanic, make sure to use BBQ paint for heat resistance.

[–] VitoRobles@lemmy.today 4 points 3 weeks ago

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.

[–] FiniteBanjo@feddit.online -1 points 3 weeks ago (3 children)

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.

[–] Lemmyoutofhere@lemmy.ca 100 points 3 weeks ago* (last edited 3 weeks ago) (2 children)

Woosh.

You wouldn’t even be able to get the pistons in the cylinder with a layer of paint on them.

[–] Montagge@lemmy.zip 27 points 3 weeks ago (2 children)

Not with that attitude! If it doesn't fit get a bigger hammer!

[–] halcyoncmdr@piefed.social 11 points 3 weeks ago (1 children)

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.

[–] Montagge@lemmy.zip 4 points 3 weeks ago (1 children)

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.

[–] halcyoncmdr@piefed.social 4 points 3 weeks ago

Large vehicle suspension components scare the living hell out of me. Seen too many videos online.

[–] criss_cross@lemmy.world 9 points 3 weeks ago

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.

[–] gigastasio@sh.itjust.works 5 points 3 weeks ago

I work with engineers, and this is exactly how they are folks, trust me.

[–] boonhet@sopuli.xyz 55 points 3 weeks ago

Why paint if you could wrap them instead, preserving the original paintwork

[–] wuffah@lemmy.world 38 points 3 weeks ago* (last edited 3 weeks ago)

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.

[–] umbrella@lemmy.ml 26 points 3 weeks ago (3 children)

to be fair it would probably just burn off immediately

[–] klay1@lemmy.world 22 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

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.

[–] umbrella@lemmy.ml 5 points 3 weeks ago

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.

[–] YiddishMcSquidish@lemmy.today 16 points 3 weeks ago

The real problem would be getting them into the block.

[–] marcos@lemmy.world 5 points 3 weeks ago

It would either be impossible to assemble or lose 90% of its efficiency in a few cycles after the paint goes away.

[–] zakobjoa@lemmy.world 21 points 3 weeks ago (3 children)

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.

[–] real_squids@sopuli.xyz 8 points 3 weeks ago

You paint the outside, like big diesel manufacturers do. Red for speed, yellow for torque, blue for efficiency.

[–] Endymion_Mallorn@kbin.melroy.org 5 points 3 weeks ago (1 children)

No, paint 'em blue, they'll be luckier.

[–] And009@lemmynsfw.com 1 points 3 weeks ago

The piston might feel blue and lose speed there. Better keep it old and gold.

[–] Track_Shovel@slrpnk.net 3 points 3 weeks ago

Found the Ork boy

[–] fubarx@lemmy.world 14 points 3 weeks ago

Be fine, as long as they don't skimp on the waterproofing.

[–] mercano@lemmy.world 11 points 3 weeks ago

You’ll need a lucite engine block to show off your shiny new pistons.

[–] X@piefed.world 7 points 3 weeks ago* (last edited 3 weeks ago)

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.

[–] PacMan@sh.itjust.works 5 points 3 weeks ago

I just pour some steel Shot Peen into a oil filler after an an engine rebuild

[–] Omgboom@lemmy.zip 2 points 3 weeks ago

Instant engine knock
