the oil cooler lines from cork sport like the same from mazda trix just about 60.00 less anyone on here had bad luck with the cork sport SS lines?
also....the bolts that go into the oil cooler and rear on the engine
they have holes at the end...(one way vavles?) for oil to go trhough, my question is do they need to be put in any certain way? i installed them on a few on my cars and all is good but the other day i installed them on a 88 base and now i get this weird whirrling sound? does this have anything yo do with oil flow? do the holes on the boltys have to be facing a certain why? please help thanks =)

The holes for the banjo bolts do not need to be oriented.

I have the Corksport lines, no problems with the install and no leaks either. So far so good *knock on wood*.

There is a certain way you can install it, forgot how it goes, but the braided lines are bent a certain way, so there's a easier way of installing it. You'll figure it out when installing. No, the bolts don't have to go in a certain way either.

I'm sure there's no specific way of installing the lines, I just compared the length and bends to make it easier to install in my car (braided lines are pretty hard, I'm sure you can install them any way you want, but I just installed it according to how the lines were bent...probably due to packing in a small box, or during production).
