Can I assume these cable melting events happen primarily near the exhaust parts, or are they more randomly distributed? Looks like I get to add more thermo sleeve to my shopping list, bonus for more under-hood bling.

On my friend's car, the cable did not melt, but it did bind up pretty well. We dissected the failed cable and determined that the outer housing had warped enough to bind the inner cable in the region closest to the turbo housing/exhaust manifold. Insulating the throttle cable from heat coming off those units would be a good start on a solution.

Interesting post on the MotoIQ blog about Sierra Sierra having turbo stud failures.

Its too bad that Sierra Sierra is a budget team and can't afford V-bands.
edit: I'm getting a real kick out of $sierra $ierra dealing problems that peasants on this board solved a long time ago. We really are great. The 3rd paragraph reads like my life with the old set-up.
Look at this safety wire job

Notice which side of the top bolt the wire lies.

Yep. And Vent to atmosphere on the valve cover and oil pan doesn’t change it I don’t get excessive blow by in the vent system anyway. Motor still shows good compression. Install stock internaled motor keep everything else the same including boost level and problem goes away. Just had to back the fuel down a bit it and it makes slightly less power and torque.

Yes; its quite strange but this is also a space-car and nothing like my peasant heap. I learned a lot from looking through a bunch of cars at RLTA last year and incorporated the ideas I could afford into mine.

edit: I'll add that they are not compatable with the stock oil squirters.
