Quick turbo oil feed question

[Zbythegods]

Hey guys, I'm looking for some been there done that answers. Just did the t28 swap and my only concern right now is that the banjo bolt on the oil feed from the block to the top of the turbo is leaking profusely when the car is running. I'm just curious on what successful setups you guys have. Do you guys run a copper washer on both sides of the bolt or only on one side? I'm running one on each side which turned out to be unsuccessful (I tighten the hell out of it too). Any advice is much appreciated. I'd go through some more trial and error but I figured I'd give a shout out to some Zilvians before wasting a bunch more hours of my life on this car.

Banjo bolts require two copper washers. You are supposed to use new ones rather than reusing old ones.

I have a KA-T and run a -3an line from a tee on my oil pressure sensor to a 90* -3an elbow to a -3an 0.035 restrictor to the gt2860rs turbo.

Normally you are supposed to run a washer on each side of the banjo bolt. If anything, run a thicker copper washer or convert the lines to -3an and you wont have to worry about washers or leaks.

Heck yeah thanks guys I do appreciate the advice. I may try the -3an line and see how I like the setup.
