  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!

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

      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.

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

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

  • FiniteBanjo@feddit.online ⁨2⁩ ⁨weeks⁩ ago

    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.

      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.

    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.

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

• wuffah@lemmy.world ⁨2⁩ ⁨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.

  to be fair it would probably just burn off immediately

  source

  • klay1@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

    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 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.

  • marcos@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

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

  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 ⁨2⁩ ⁨weeks⁩ ago

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

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

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

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

  source
• X@piefed.world ⁨2⁩ ⁨weeks⁩ ago

  For guaranteed extra performance, get a student machinist to mill Z3 vents on the tops of the pistons. Less aero drag means pistons reciprocate faster, faster pistons means more powah.
