Recently got a new oil feed line as my old one was coked full of oil and ruined my turbo which I had to get rebuilt.
I bought "TALL RESTRICTOR -4 size .035" Oil inlet fitting" from ATP but it leaks where it screws into the turbo, and there isn't a way to use a crush washer. Don't think I should use thread sealant right?
I had this happen last time with another AN type screw fitting and ended up just using a banjo bolt but thought the ATP fitting would be better quality.
It doesn't leak all the time, just when the two materials are probably drastically different temps during warm up or cool down between WOT runs.
Who saga has me curious what other people are successfully using?
Turbo oil feed, banjo bolt or other?

I use a -4an with a 90 degree end for mine and appropriate -4an adapter on my turbski. No leaks here.

For the -4an adapter to your turbo do you use any thread sealant? Crush washer? O-ring?
Re: Turbo oil feed, banjo bolt or other?
I am not sure what turbo you have.. maybe I missed it?
For Garrett turbos with BB I use this fitting. It needs long threads so the flare seats on the insert inside.
AN -4 , 7/16"-20UNF
For GT25R / GT28R / GT28RS / GT30 / GT35R & More Turbos
Restrictor (Hole Size) :0.9mm (0.035")
If your turbo has M10 threads it needs a straight or banjo fitting with a washer.
