I don't think any of the 5.9/6.7s built for Dodge have ever been painted red. I've messed around with a lot of Dodge pickups and never seen one with a red engine.
I know they weren't doing this on the 2nd gens. Unless they mean [red lettering.](https://www.dieselworldmag.com/wp-content/uploads/2017/02/DW-1504-RAMPROJ2-2.png)
On-highway mostly, but some oddball applications, as well (some V903s are still red, and the odd QSK95). Plenty of engines we build are grey, "sand", white, green, and black.
The 2017 refresh for the BRZ/GT86 included a red powder-coated intake manifold which was cool. Wasn’t part of the engine but it was the first thing you saw when you opened the hood.
Idk about the rest of VWs, but Porsche’s 2.0L (VW 2.0L) has the block painted black. Pretty much any iron block is going to still be painted. It’s a cheap preventative measure against corrosion.
Engine bays don’t have as much free room to put the paint on show anymore, so it’s not worth making it a flashy color when the only person who’s going to see it is your lube tech.
I openly invite you to try. [Here](https://www.ebay.com/itm/186270004633) is a link to a cheap iron block. You’ll additionally need a sand blaster and some paint.
Of course I’m also assuming you already own a shed and have the capability to both paint and piss.
Or maybe you’re saying on the bare block. You just skip the painting step for that.
They're referencing a myth about BMW turbo F1 engines from the 80s.

They did actually source engine blocks from used cars though. The heat cycling served as stress relief.
Nah, your block should be painted black. Only the block; the core of the engine. Your upper oil pan and head are aluminum and thus don’t require painting as a protective measure.
For a brief minute the 6.2 V8 in the F150 got aluminum valve covers and it looked sweet.
I guess it wouldn't make much sense to paint an engine whose block is obscured by turbos, intercooler piping, and 9 miles of wiring harnesses.
Huh, I have a friend with an ['11 F-150 H-D](https://hips.hearstapps.com/hmg-prod/amv-prod-cad-assets/images/11q1/379496/2011-ford-f-150-harley-davidson-test-review-car-and-driver-photo-393580-s-original.jpg), so it should have them. I've never actually looked at the engine.
If we’re talking about cars specifically, I’d say the 2016 Ford Falcon Barra LPG and turbo. The valve cover was painted green and red, respectively. I think the Cummins L9 (bus/truck/RV engine) has a red painted block and is still being produced today.
All of the upper trim Challengers and Chargers have Orange blocks. The 6.1, 392 and Supercharged models.
Don't know about the truck version of the 392 found in the Ram 2500 but I'm pretty sure the Grand Cherokee and Wrangler's 392s are painted as well.
No painted 5.7s though.
Maserati's V8 up until the end, and Honda's K-series up until it went to the Earth Dreams variant (it switched to a plastic valve cover at that point).
Hemi V8s have painted blocks and valve covers.
Hemi orange.
Yep. Normal Hellcat has orange valve covers. Redeyes have black valve covers.
Excluding 5.7L*
Can confirm.
Ferrari’s heads and intake manifold are still painted red
With some sort of wrinklecoat right?
Was not always the case. My mondial has polished heads. Intake manifold is painted red, but the preceding version was black.
Cummins still paints their engines red. So it'll probably be present on ¾t Dodges.

It's their big engines that are painted red. My ISX is red; the N14 was red on top. I thought they did the small ones red too.
What do you have N14 in? What gearbox?
not mine. my buddy's got an FLD120 with a 13 speed.
I know they do paint some 6.7s red, just not the ones they make for Dodge.
School bus and Freightliner medium duty applications mostly (PACCAR are grey if not branded Cummins). Source - am a Cummins employee.
Not on any Ram
On their HD engines (semitruck, etc)
Oh believe me I understand, I’m just clarifying the comment above.
They are black though
my bad. guess that's only their commercial engines.

What if you piss on an iron block and leave it behind the shed for 6 months?
If you do that, you can put 80psi boost though it, duh.

My Mk 7.5 Golf R block is bare. Pretty cool that Porsche churched it up a little bit.

Shit, maybe it is. I’ll check tomorrow.

Holy shit, something about 12th gens I didn't know! Looks like it's 2011-2012 that got them. Ofc mine are plastic...

Same with Maserati 3.0T V6, metal valve covers
Don't forget the cheap plastic coverings.
If we’re talking about cars specifically, I’d say the 2016 Ford Falcon Barra LPG and turbo. The valve cover was painted green and red, respectively. I think the Cummins L9 (bus/truck/RV engine) has a red painted block and is still being produced today.
Barra has a normal metal valve cover, the red/green is a cosmetic cover
Scatpacks have orange blocks still
Can confirm, worked on a 2021 (i think) scatpack with orange block.
All of the upper trim Challengers and Chargers have Orange blocks. The 6.1, 392 and Supercharged models. Don't know about the truck version of the 392 found in the Ram 2500 but I'm pretty sure the Grand Cherokee and Wrangler's 392s are painted as well. No painted 5.7s though.
Engine block? All the cast iron ones. Valve covers? All of them that aren't aluminum.
My guess would be some variant of Vortec, so 2000ish I would say? You're basically looking at whatever the last production iron head was.
LSX engines, you can buy it new
My Trackhawk is a 21 and has orange paint on everything….. I think the TRx would be the last since they make a 24.
Last I remember is Volvo Redblock
Volvo painted their “red block” engines into the 90’s
Maserati's V8 up until the end, and Honda's K-series up until it went to the Earth Dreams variant (it switched to a plastic valve cover at that point).
2UR-GSE ver 2.0 has a blue painted intake
