I'm using a -10 braided oil return line.
It touches on the manifold and I noticed that it started leaving little burn marks on the line.
What kind of sleeve can I use to protect the line from ruining?
I purchased the DEI Heat Sheath Protective Sleeve, but I don't feel confident that this will hold since it touches on the manifold. Is there anything else? Has anyone had a similar problem before?

 

My oil return is up against my downpipe so we wrapped it in something similar to that, havent had any problems.. yet.

 

I've got so many heat problem I don't know where to start. I wrapped my line with the DEI Cool Tape (1500 deg), and then re-wrapped it with a fiberglass exhaust wrap, then wrapped another 2-3 layers of the cool tape where the line actually makes contact with anything. The heat sheath you show above is only good up to 500 degs.

If your seeing burn marks on the line, keep an eye out for any oil leaks that may indicate that the inner liner material has been compromised.

 

Bump cause my -3an feed is contacting my manifold. I jammed a piece of heat wrap material between the manifold and the line cause its a greddy manifold and cant really be wrapped.

Im thinking it would be hard to ruin the inner tube with oil running through it to cool but I have a long road trip in a few days and I really cant have this bursting on me.

 

depending how much touches I would use a DEI Protect-a-boot thats used with spark plug wires, Its rated at 1200 deg direct continuous heat. but its only 6" on top of the heat sheath.

 

I have 2 pieces of heat wrap between the manifold and the line and Im going to wrap another on the line itself.

 

There is a aspestose wrap you should put on it. I think Earls sells it. I think you can find it on ANPLUMBING.COM
