hey guys i have a peakboost top mont manifold, w/ a GT35r and the oil return line is giving me fits. It is resting on my manifold. It has allready burned into my return line. Which had a sleave around it that was supose to hold up to heat. Which it did but only for about an hour. So I replaced the line w/ stainless steel line that can handle 500 degrees. But I know that is not enough. Do you guys think that this stuff would work??

This is more like what you need



that wrap stuff should be for manifolds, downpipes, exhaust and such. I use this and my return line touchs my exhaust so alot to worry in case things get too hot.

 

that is what i had on there and it failed.

 

Is there any way to route the oil return line away from touching the header? There has to be something like that you can do...

 

My return line on my S is sandwiched between my dumptube and my manifold. both of those are heat wrapped, and i have heat shield sleeve covering my braided stainless steel return line. So far there hasn't been a problem, but here is what i did.
I figure the manifold is a constant source of heat, so i made it so the return line is not resting on the manifold, but it is touching the wrapped dumptube. The dumptube only gets hot when you are hitting full boost, where as the manifold constantly has very hot exhaust gasses flowing through it.

 

there is no other way of routing the line. I will post a pic of it tomorrow.

 

That silica stuff may help, but I can tell you the adhesive will disintigrate in no time, so use clamps. The flame guard is probably nomex, which will only help if it's not directly touching. Nomex chars instead of burns but still transmits heat, so you need insulation below it for constant-heat protection.

Otherwise just do what smart people do in most cases, wrap you downpipe in fiberglass. I can comfortably rest my hand on my DP 6" from my turbo after a beat run, while my infrared thermometer reads over 800F at the flange. I tell people who are worried about looks, "You should stick to body work, not turbocharging".

 

i don't think that wraping my down pipe is going to do anything. As the oil return line doesn't touch the down pipe. Here are the pics as promised.
