So my original intension was to change out my downpipe and in the process of doing so, i broke one of the bolts inside the o2 housing. Because of that, i ended up taking out the turbo and drilling out the bolt. Taking out and reinstalling went smoothly. When i turned the car on, a ton of oil started leaking from the oil feed bolt to the turbo. I tried tightening it some more but it didnt want to tighten any more. So I'm wondering if theres like a "one time use" gasket or seal for that bolt??? Other than that, I have no idea why its leaking from there. Any help would be appreciated. Thanks

 

+1 for any advice.
I recently did a full bolt-on plus turbo swap build and once I turned it over my high flow oil feed line started leaking oil also. Not sure on what the problem is and this is the only thing holding me back from driving my car.

 

I experience the same also when I did my o2 down pipe. Just re adjust the oil washer and you will be good.

 

I did that today. I took out the banjo bolt and made sure the crush washer was where it needed to be and put it all back together but its still leaking from there. I have no idea what to do!

 

I did the same. Have tried different washers also and nothing works.

 

you have both crush washers top and bottom? im pretty sure you are supposed to replaced the crush washers.

 

Yes, you need to replace the crush washers each time. I prefer copper, but aluminum ones will owrk as well.

Take the old ones off, go down to napa and they have a whole drawer of them in different sizes. ask them to match it up and then get some extras. they are less than a $1 each

 

Yup it has to be the crush gaskets because i just did a turbo swap in my car but i replace all the lines with Stainless Steel braided lines but i had brand new crush gaskets and i had no leaks at all! So gt brand new crush gaskets unless the line is cracked but hopefully that is not the case
