Hi everyone,

I've attached a picture and my question is, that turbo oil feed is 10mm from the hot side of the turbo, is any damage to the pipe likely to occur from heat at that distance?

The OEM line was solid but because I've changed the turbo and had a custom hose made the manufacturers of the hose couldn't build that up and over section in solid pipe any insight is much appreciated.

Hi James,

Theres nothing wrong with what you have there; I would personally try to rotate the fitting around so that it is towards the middle rather than towards the turbine side of the turbo.

Always make sure you use steel fittings on a turbo as I have seen people use aluminium fittings which in time can a, loosen b, snap!

You can also use something like this : -

to wrap the hose in (if your making the line it’s much easier to fit before finishing the braided line off with the fitting. You can use a small bit of stainless lock wire to retain the sheath in place.

If it’s a new line that’s been fitted I would also check it after the first fire and frequently for the first few drives/uses. Th fitting might need a little nip more as it goes through heat cycles.

Hope that helps!

Dave nailed it.

Aluminium (aluminum to the heathens) is a very useful material, but it is prone to work hardening and fracturing and (one of) the last things you want is a broken pressure line spraying oil over a, potentially, red hot turbocharger

Thanks guys, it's nice to have a 2nd pair of eyes on something.

That firesleeve is a neat looking product, I'll be getting some of that for the line. Where the line routes under the turbo and over the heat shield around the exhaust manifold it rests on the heat shield (because it no longer has the rigid solid section of the OEM one) so I'll need an insulating standoff to keep it out of contact of that as well, my initial thought was something ceramic or a piece of carbon foam or little bit of aerogel, is there a product or system that already exists for this?

I'll keep an eye on that bolt tightness so thanks for that as well, I always like to keep unexpected fires to a minimum.

Hi James,

Always glad to be of help; do you have a picture of the area? I personally would play with the routing and attach the line to solid items (like the head etc) with glued on tabs and again little bits of lock wire or heat proof zip ties (little green looking ones - if I find where we used to get them from I’ll post up a link)

I think that clears that one up as well then as my temporary, as in first start up solution, was what you chaps are recommending so stainless steel ties to keep it isolated from that guard it what I'll do. Thanks again, and when I've got it all up and running no doubt I'll be back when I properly start the new engine build. Cheers guys
