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.

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 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.

Ford 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.
