Header exhaust leaks

[3bals]

The headers are back on. Now we are trying to figure out how to shield the shift cable from the exhaust. The cable runs between the down pipe and the manifold that runs to the turbo collector. We were thinking to run the cable inside of metal flexible conduit, then wrap that.

The problem with a metal condiut is any heat that permeates it will be trapped against the cable. Do a layer of header wrap first then the condiut, then more header wrap?

That's what I was thinking, too and get big enough conduit to provide a little air space.

Old coffee cans makes pretty good heat shields too, keeps the bigges amount of heat away, still would want to protect the cable though.

Consider DEI (Design Engineering Inc.) Heath Sheathing or Spark Plug Wire Protection?

Aluminized stuff comes in 5 different Dia. https://www.designengineering.com//...line-sleeving/heat-sheath-aluminized-sleeving

Header wrap and paint the wrap with high temp header paint to lock it in place. You can lean on the manifolds with header wrap without burns after a full pull on my truck. Stuff's that good so you don't need to go crazy.

Wrap before the turbo blanket... IMO All you need.

Just got word from the shop, the flex conduit that will fit over the existing heat barrier on the shift cable won't fit where the cable has to run. So, coffee cans here I come.
