I don't think it's any harder to turn the engine backwards than forwards -- you're still working against the same volume of air being compressed in the same number of cylinders. Depending on valve overlap the compression might be slightly lower, in fact. The idea that backwards is harder because it's "wrong" is just a myth.

The problem with turning the engine backwards is that, while the crankshaft can probably turn fine either way, the valvegear is very much not designed to go backwards in most modern engines. The lobes on the cams may not be ramped correctly, and the timing system might be designed to only experience tension going in one direction.

Fun fact though: some diesel engines with electric fuel pumps and symmetrical valvetrains can run equally well in reverse, except that air gets sucked in the exhaust pipe and exhausted out the intake, which is spectacular to watch but real bad for everything that is not the engine itself

I used to be into high-performance 2-stroke engines for small personal watercraft (standup jetskis). I had one setup with a lot of ignition advance and a very light flywheel. It was possible to nearly stall the engine with a particular maneuver and have it come back running backwards. Indications were rough running and no appreciable jet output. But it revved just fine.

Yeah, one of my work machines has a kubota diesel, and it mentions in the manual what to do if the engine starts running backwards.

I seem to recall there being a buick engine from the 50s that guys would make run backwards with custom manifolds...

Modern 2 stroke Snowmobiles achieve reverse by stopping the engine and running it backwards.

My parent's 84 Caprice station wagon had the same tailgate as the "innovative" Honda ridgeline tailgate. I can see its purpose though. Drop it like a tail gate for long poo poo, tailgate parties, etc, or open it like a normal door so that we could pile in the very back seat.

But this? Or the one on the ridgeline for that matter?

Hell my 95 Caprice wagon (and all the varieties) do this as well.

The coolest one is the Chevy Kingswood Wagon circa 1970 or so. The tailgate basically slid down into the body and disappeared.

It's real bad for the engine too. The oil pump runs backwards, sucks the oil from the engine, and dumps it all back in the pan.

I've gotten a gas/LPG dual fuel motor to run backwards. Someone filled the tank with diesel, and even after we flushed it when we tried to run it on gas it would idle like poo poo for a few seconds, almost stall, then spin in reverse for a half second before dying. Did that a bunch of times until it would actually run (like poo poo) on gas, and then it sounded terrible for another 10-15 minutes. Ran great after that though. I feel bad for the sucker who wound up buying it, though.

I agree that running it backwards is bad, btu...

A few revolutions backwards aren't going to hurt anything. Yeah, no oil pressure, but you're talking a handful of revolutions, immediately after it's been running (or at least running enough to build oil pressure). You have no oil pressure when cranking it after sitting overnight; for the first second or two your engine's lubrication is whatever was leftover from the last run. Depending on the car it MIGHT build a little bit of oil pressure before it fires, but as the engine gets more worn out, oil pressure takes longer to build. Supposedly synthetic clings a lot better after the engine sits awhile, which is why I refuse to use anything except synthetic (even on my 200k Saturn). So long as the timing chain/belt doesn't jump from that, it shouldn't be an issue.

The only thing I'd be worried about on that, assuming it only ran backwards for a couple of seconds at a time, would be the oxygen sensors and catalytic converter. And that's just because O2 sensors and cats designed for a gasser don't cope with diesel too well.

Now if I ran across a diesel that someone had filled and tried to run with gasoline... oh god, unless it was scrap price, I would run like hell unless they had receipts for the entire fuel system, from tank to injectors, and I'd still want a compression test. The injectors and high pressure fuel pump rely on the extra lubrication that diesel provides to function properly. poo poo gets hosed in a hurry. If you fill it up and realize your fuckup before you try to run it, it's more of a matter of "drain and flush tank, change fuel filters/fuel+water separator in case they cycled the ignition on, call it a day".

Until you de-prime the oil pump then make all the expensive noises almost immediately after start up.

Some cam chain tensioner designs allow the plunger to fall out when the cam chain runs the wrong way, which will almost certainly see you jump timing and save you from bottom end expensive noises; interference motors will give you a consolation prize with some top end expensive noises.

As a rule of thumb: Don't spin modern 4 strokes the wrong way*.

*: Please someone find a Maserati that spins the engine the wrong way instead of having reverse gear.

That engine probably isn't running backwards, it's just running reverse-flow. Nailheads have terrible ports, and tiny valves (that's why it's called a nailhead; The valves look like nails,) so it looks like that guy is trying to get around the awful valve setup by using a blower, and just brute-forcing the smaller intake valve. Drag racing didn't get super-scientific until the seventies or so. Before that, there was a lot of throw-poo poo-at-the-wall-to-see-what-sticks going on, which that digger is a prime example of.

IIRC, there was a reverse-flow flathead that set some class records out at Bonneville a few years ago. (Maybe a decade ago... :corsair:)

Oh God they're like that outside of the US, too?

I always thought for cars where the brake and turn signal was on a trunk lid or liftgate, there would be a smaller (mandatory) duplicate signal on the bumper that would only activate when the trunk or liftgate was not closed. Of all the other cars that I've seen this arrangement on the road (Audi Q3, Q5, & Q7, Lincoln MKC, Chevy Bolt), I've never seen the auxiliary lamps light up.

So when I first saw the new model Clubman on the road, I also noticed that the bumper lamps where lighting up instead of the supposedly main lamps on the rear gate. I just figured that, being a Mini, there were some electrical or controls issues that made the car think the rear gate was open and only used the bumper lamps. (Yes I know Mini is more BMW at this point.) As I saw more Clubmans on the road, though, I realized that that is how they're wired at least in the US despite how stupid it looks. They spent all that time and effort designing the "main" cluster but instead use plain and generic lamps on the bumper for actual signaling. So despite at least Audi, Lincoln, GM figuring out how to do backup auxiliary lamps, I can't figure out how Mini/BMW couldn't do it as well unless they were prevented by the electrical design being so hosed up and inflexible.

I wouldn't be surprised if the wiring is wrong in these from factory. If it's not wrong and this is intentional then lol at BMW.

It may be for when you have the side lights on only perhaps? Either way it's completely loving stupid but is a nice example of a modern Mini design decisions being utterly dumb.

That's probably true for the engine I had. I meant more generally, though. Having an engine run in reverse is bad for the internals, as well as exhausting out the air filter.

I've seen gas in a diesel before, and it really depends on the motor. I got called to a site because a boom lift was running like poo poo and had no power. Fired it up and it just had the worst clatter you ever heard. Like, you know the sound when you try to start a diesel using ether? Like that but constantly, and then it would die immediately under load. Sure enough, gas in the diesel tank. Drain, change the filters, try to purge the lines, and it still sounded horrible. I almost gave up on it, but 10 seconds after I got off the phone saying it had to be removed from site due to permanent injector damage, it purged the last of the gas and took off. The company I was working for was cheap af so we left it at that and it ran great for like 2 more years before they sold it.
