Oil cooler leaks question.

wstar

I used Stillen's kit, including their lines, which have the steel-braided sheath on the outside like many. I did like you mentioned above: I ziptied some protective rubber over the pair of hoses everywhere they could rub, esp where they contact other lines (power steering), frame/body, etc. A slit section of large diameter heater hose is great for that.

And as for failure risk, IMHO if your system develops a weak point (a fitting or hose getting weak somewhere), seems like the most likely time to blow it would be a cold morning startup in the winter off the track, those are really the highest PSI, and the fittings and sheathing are super cold at the time as well (more brittle, and slightly shrunk). On the other hand with a thermo plate that may mitigate *some* of the extra pressure spike on cold start, but certainly not by a lot (it's just going to be more of a static pressure without a lot of flow once things level out).

Yea they all have the SS braided lines. But Z1 also offers another type of sheath that heat shrinks over the SS lines for even more protection. I didn't really want the SS lines themselves rubbing.

I noticed I had a small leak after a week of running. It was the way the arm was facing. So I re-tightend the hoses with a little bit of a angle so that it would "constantly" try to tighten itself onto the cooler. But yeah I agree with what you said as far as its probability of leaking would be startup!
