Do I need a flex section on my turbo oil feed line tubing?

I just made up an aluminum tube for my turbo oil feed line. It goes from the oil filter housing to the top of the turbo and is one solid tube, but with many bends. Do I need to add a flexible section to this tubing where it connects to the turbo? I'm hearing mixed feedback from some other people with one guy saying he had a solid tube which loosened and dumped oil all over the hot turbo.

Thanks!

If the length and position of oil feed line is correct there is going to be no issues. However, if the line is under tension or engine is noticably vibrating it can come off loose...

It will depend on the pipe's route, the materials used, how tight the fittings were, etc.

The important thing is usually that the pipe can flex over it's length, a little, at the turbo' and manifold moves as they heat up. That shouldn't be a problem there, because it isn't a direct run between them. If you're that worried, use some blue loctite during assembly.

I do have a bit of a concern with the pipe you used, though, as it's poorly made (pick up a cheap pipe bender, it work wonders), and the large overhang means it would be expected to vibrate a lot, and as aluminium workhardens, I would expect it to fail eventually, with undesireable results. You should be able to pick up a length of steel tube (Bundy?) cheaply, which should be perfect.

Thanks for the replies!

I should've mentioned that the creasing you see is just the Textalu heat sleeving. I used a tubing bender and all the bends are smooth, it's just some bunched up heat sleeving on the inside corners.

The tubing I used is 3003 aluminum, but I can definitely change that out for copper nickel or even stainless if that would be better. I figured for this application aluminum was suitable though.

I will also be securing it in a couple spots, for now this was just a mockup.
