hi there,
can anyone tell me if you can run hot oil through ss breydid brake lines?
i have a load left over,im thinking of useing it for my turbo feed?

99% sure its the same line....so yes

No reason why not, brakes can get really hot, on racing porches they had to substitute the lightweight ali calipers for heavy iron ones as the started to melt with carbon brakes.

just make sure its a big enough bore as braided brake lines are very small ID, turbo feeds are also small but not sure if they are that small.

If the braided lines use rubber inside the answer is NOOOOOO. Petroleum based products will destroy the rubber very rapidly.
No idea if they are teflon/plastic hoses though. Best ask the manufactuer.

nice ass,
thay are a white plastic, i also asked my mate he said that i would be fine,but as im using minaral 20/50 oil you should change oil and fliter at 3k or less so i dont get any blocking

Using 20w/50 mineral oil is a quick trash a turbo.

You need 10w/40 at least part synthetic to avoid the oil breaking down in the turbo after switch off. 10w/40 migh also give the Pinto cam a half a chance of surviving.

Ah yes - good points raised. I assumed that the lines would be teflon/stainless but the bore would have to be sufficient for sufficient flow to the turbo (it uses quite a lot of oil...).

Semi-synthetic in the 10W40 (maybe 15W40 at a push) is a minimum - and even then keep your oil changes regular.

Wasn't quite sure how to take that until I realized you were talking about my avatar picture

The white teflon/nylon lines are *probably* fine but they may harden and crack over time. I would ask the manuf of the lines if they are suitable for petroleum products.
Cheers.

we use stainless braided ptfe/teflon lines for turbo feeds and there have never been any problems, you should be fine.

ok i have found out that its ok to use 20/50 with a turbo but just make sure you change the oil and filter say 2-3k,
the thing is as you know,the pinto only likes thicker oil and the turbo likes thiner,
so i think as you say im gona try and meet in the middle

Two problems with using 20w/50 mineral oil

(1) Camshaft lubrication from a cold start --- 10w/40 will double the the camshaft life.
I change dozens of Pinto chanshafts durring the period when it was used in the Cortina & Transit.

(2) When mineral oil is over heated (as will in a turbo bearing) mineral oil breaks down to form varnishes gum the varnishes and gums stick the the surfaces of the oil ways and don't drain away with the oil at an oil change.
