I'm honored - sure makes my day :-)
Update 10/16/2013 -
Interesting comment by tekochip:
"Another example of complex systems failing in complex ways. As the
pre-catalyst fails you would think that the exhaust gas pressure would keep all
the containments from flowing back into the engine, but the MR2 engine features
variable valve timing. Under some conditions the valves change their timing to
allow a little exhaust gas back into the cylinders, sort of a vale timing
version of EGR. So, with the variable valve timing sucking in exhaust and the
pre-catalyst failing, the result is containments scoring the cylinder walls and
valves."
Rob Spiegel chimed in, confirming that the pre-cat problem is all over the Internet:
"This seems to be a widespread problem with
this model. A quick Google search found TONS AND TONS (emphasis mine) of references to pre-cat
problems."
Absolute disgrace that government allows corporations like Toyota to kick consumers around with such impunity.
Update 10/19/2013 - I'm delighted to see comments focusing on pre-cat environmental considerations and the EPA. Instead of coddling Toyota with wrist-slappin' fines, and allowing them to cut deals whereby Toyota makes no admission of wrongdoing, government should have reigned the Recall King in long ago on the pre-cat issue.
