I've been lurking this website for awhile and finally decided to join. I like Hondas and Half-Life and not much else.

I think Pitz is in love.
This is just very inefficient subliminal advertising, guys.
Toyota, moving forward. And forward. And we're still moving forward. And we can't stop moving forward. Somebody please stop us. Oh, nevermind that tree stopped us. :x
This applies only to "modern BMWs" whatever that exactly entails.Modern BMWs don't have to worry about the effects described above, because the DME (car's computer) that controls the engine will detect that the engine is burning leaner than before, and will adjust fuel injection to compensate.
http://en.wikipedia.org/wiki/Exhaust_gas_temperature_gaugeBy monitoring EGT, the driver can get an idea of the cars air-fuel ratio. At a balanced air-fuel ratio, the exhaust gas temperature is lower than in a lean or rich air-fuel ratio. High temperatures (typically above 1600 degrees F) can be an indicator of dangerous conditions that can lead to catastrophic engine failure.
As you probably know, the camshaft is a long rod that makes the pistons go up and down in the correct sequence. I believe what crank walk is, is simply the rod (the crank) has worked its way (slid) to the side a bit.CyberPitz said:Then again, no matter how many times I try to understand "Crank walk" I just can't wrap my head around it.
http://en.wikipedia.org/wiki/Mitsubishi_Sirius_engine#4G63Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Mitsubishi Galant VR-4, Lancer Evolution, Carisma GT and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four sequential WRC championships in his Lancer.
The Mitsubishi Eclipse, Eagle Talon and Plymouth Laser introduced the DOHC turbocharged intercooled version to the U.S. in 1989 through Diamond Star Motors, a joint venture between Mitsubishi Motors and the Chrysler Corporation.
And it's such an awesome powerplant.In the United Kingdom, a special Lancer Evolution, the FQ-400, produces 302.13 kW (405.2 hp), from a 4G63 engine. At 202.6 hp (151.3 kW) per liter, it has the highest specific output per liter of any production engine.
As you probably know, the crank is a long rod with raised areas that push the spring-loaded valves up in the correct sequence. I believe what crank walk is, is simply the rod (the crank) has worked its way (slid) to the side a bit.
You hear a lot of talk about it, but I believe this is actually a fairly rare problem in a 4G63 turbo engine. (my engine)
EDIT: decided to search "Crank Walk" and LOL:

I can't believe this shit made it to the Urban dictionary. Holy christ, that's hilarious.
It had been about 10 years ago when I heard about it, and saw DSM'ers so scared of this shit, so I did a ton of reading on it, only to find out how overblown this issue is.
Of course, I didn't realize then, that if you search for a rare problem, you might find a lot of people talking about it. That doesn't necessarily mean it isn't rare.
