Piston Slap: A Triumph Over A Sticky Clutch?

TTAC commentator krhodes1 writes:

Hi Sajeev,

Here is one for you and the B&B: ’74 (more or less) Triumph Spitfire with a clutch issue. The clutch feels “sticky”, doesn’t release smoothly, and makes starting off in first a little challenging. Otherwise, the clutch works fine once you are moving.

Piston Slap: My Pick Up's Failing Clutch Pick Up?

TTAC Commentator halftruth writes:

My 2012 Tacoma has a temperamental clutch. Sometimes it catches high, sometimes low. This is most annoying on a grade when the pedal comes up and very little happens, then — boom! — it grabs all at once or it catches a little at a time and eventually works as it should. The ambient temperature does not seem to matter nor if the truck is hot or cold.

I noticed the pedal linkage is all plastic and has lots of play in it. I have also noticed this in other Tacomas of the same generation. I did adjust the actuator gap as it was way out of spec at about 8 mm, but it did not make a difference.

Too Big To Fail, Too Confused To Operate: Analysis Of 619 Pages Of Cobalt Engineering Documents [w/ Full Text]

The House Energy & Commerce Committee recently released the documents GM submitted for investigation, which includes emails and internal reports documenting GM’s response to reports of their early Chevrolet Cobalt and Saturn Ion models inadvertently shutting the car “off” while driving due to an ignition cylinder that was, simply, too easy to turn out of the “run” position; and in the case of several accidents, allowed the ignition cylinder to rotate out of the run condition before or during accidents, causing the airbags to not deploy when required.

The documents, totaling 619 pages (some with repeat info), reveal just how deep seated “old GM” was in their cost cutting ways (Driving down supplier costs to the point of sacrificing quality, admittedly poorly designed ignition cylinder, and removing internal quality control on the parts), and just how blind sided “new GM” was during their investigations. It also confirms how suspended engineers Ray DeGiorgio and Gary Altman were involved in the ignition switch response, and fuzzy problem solving. Full text and an analysis of key documents below.

PRI 2013: Ford Shows Off Its Ecoboost Crate Engine

Ford Racing quietly began offering its advanced, 2.0 liter Ecoboost turbocharged 4 cylinder crate engine earlier this year, without much fanfare. All that changed at the 2013 PRI Show in Indianapolis, however, with Ford’s Ecoboost powered 2015 Mustang twirling away on a giant lazy Susan directly under the giant “Ford Racing” banner mere steps away from the small crate engine, displayed proudly with its (relatively hefty) $8,000 price tag.

  • Jkross22 Their bet to just buy an existing platform from GM rather than build it from the ground up seems like a smart move. Building an infrastructure for EVs at this point doesn't seem like a wise choice. Perhaps they'll slow walk the development hoping that the tides change over the next 5 years. They'll probably need a longer time horizon than that.

  • TheEndlessEnigma These cars were bought and hooned. This is a bomb waiting to go off in an owner's driveway.
  • Kwik_Shift_Pro4X Thankfully I don't have to deal with GDI issues in my Frontier. These cleaners should do well for me if I win.
  • Theflyersfan Serious answer time...Honda used to stand for excellence in auto engineering. Their first main claim to fame was the CVCC (we don't need a catalytic converter!) engine and it sent from there. Their suspensions, their VTEC engines, slick manual transmissions, even a stowing minivan seat, all theirs. But I think they've been coasting a bit lately. Yes, the Civic Type-R has a powerful small engine, but the Honda of old would have found a way to get more revs out of it and make it feel like an i-VTEC engine of old instead of any old turbo engine that can be found in a multitude of performance small cars. Their 1.5L turbo-4...well...have they ever figured out the oil dilution problems? Very un-Honda-like. Paint issues that still linger. Cheaper feeling interior trim. All things that fly in the face of what Honda once was. The only thing that they seem to have kept have been the sales staff that treat you with utter contempt for daring to walk into their inner sanctum and wanting a deal on something that isn't a bare-bones CR-V. So Honda, beat the rest of your Japanese and Korean rivals, and plug-in hybridize everything. If you want a relatively (in an engineering way) easy way to get ahead of the curve, raise the CAFE score, and have a major point to advertise, and be able to sell to those who can't plug in easily, sell them on something that will get, for example, 35% better mileage, plug in when you get a chance, and drives like a Honda. Bring back some of the engineering skills that Honda once stood for. And then start introducing a portfolio of EVs once people are more comfortable with the idea of plugging in. People seeing that they can easily use an EV for their daily errands with the gas engine never starting will eventually sell them on a future EV because that range anxiety will be lessened. The all EV leap is still a bridge too far, especially as recent sales numbers have shown. Baby steps. That's how you win people over.
