Well that Focus is a lot heavier, due to insane beltlines and mandatory safety equipment.

D C posted:My thought was an exploded transmission sending the motor flying breaking the mounts. When they first get an up close shot of the aftermath you can see the bellhousing has been shattered and the entire flywheel/clutch assembly is missing. The radiator support is bent away from that area of the car from an outward explosion. High RPM + lovely bolts/unbalanced assembly is what I'm thinking. That kind of force could gut everything in its path. I think there was a video a couple pages back of a small block on an engine dyno that sent its flywheel through a few walls/metal cabinets when it failed. Edit: All I can find is this; http://www.youtube.com/watch?v=L2pz1PkhAo8 "I'm FREE!" and this; http://www.clubcobra.com/forums/showthread.php?t=80533 Makes me nervous about putting on my new chromoly flywheel in my mr2.

Good lord, my volvo builds up something that looks exactly like that on the oil cap. Yet the oil comes out the standard black (grayish from excess gas, short trips) That looks nasty as hell.

I talked to a local guy that worked at some GM dealership, he said book labor was something like 4 hours for those and headgaskets or whatever but he did em in 45 minutes or so. I guess he had a little practice...

ratbert90 posted:yep, instead of you know.. balancing everything from the factory they were lazy. Has nothing to do with balance of rotating assembly. wikipedia posted:While an optimally designed V6 engine would have a 60 degree angle between the two banks of cylinders, many current V6 engines are derived from older V8 engines, which have a 90 degree angle between the two banks of cylinders. While this provides for an evenly spaced firing order in an 8 cylinder engine, in a six cylinder engine this results in a loping rhythm, where during each rotation of the crankshaft three cylinders fire at 90 degree intervals, followed by a gap of 90 degrees with no power pulse. This can be eliminated by using a more complex, and expensive, crankshaft which alters the relationship between the cylinders in the two banks to give an effective 60 degree difference, but recently many manufacturers have found it more economical to adapt the balance shaft concept, using a single shaft with counterweights spaced so as to provide a vibration which cancels out the shake inherent in the 90 degree V6. link ab0z fucked around with this message at 20:46 on Mar 31, 2010 |

I hate balance shafts, I really do, and putting them in I-4's is even worse as they shouldn't need them at all. Yeah those Porsche guys especially, when will they learn how to build cars. I was under the impression that balance shafts aren't just for compensating for a builder- or design-created imbalance across the crank and rods, they create an opposite wave pattern that cancels the resonance of the crank. Engines without balance shafts don't need them not because their rotating mass is built "better" but because the crank's vibration is being compensated for another way, perhaps with a harmonic balancer, a reduced redline or simply being overbuilt and letting the bulk damp it. e: nevermind, realized who I was arguing with

Splizwarf posted:Yeah those Porsche guys especially, when will they learn how to build cars. you seem to misunderstand me. I don't hate any particular company, and am not a rabid fanboy of any motor/make/company. If anything, I just like well built motors. If they have problems I don't care who it is. GM/Ford/Toyota/Honda/anybody else. There are great engines of all the companies out there also. Era specific sure, but good engines non-theless. Why is that so hard to comprehend to some people? I don't like balance shafts, Honda hasn't used them, no harmonic balancer, 7200rpm redline, and not really overbuilt at all. My 3sge doesn't have them, again, high redline and not overbuilt. Also very quiet, even with a 2 inch exhaust. To me, every engine I have worked on that HAD a balance shaft wasn't properly designed. Weather or not this is a huge issue in the long run of things isn't the issue. To me and what I think it just screams bad engineering and I shouldn't touch the motor. Thats all.
