I run a .060" restrictor in my journal bearing turbo (fitting with a .060" hole) but I agree with @patsmx5 if you have a leak at the fitting thread it's a different problem.
I'm trying to figure out how one determines if the restrictor is necessary without blowing a seal first. Thirdgen got back to me saying he installed it because he didn't want to risk blowing a seal.
What's too high a pressure for a JB turbo? I'm 99% sure the drain is a 10AN, so the line ID should be >14mm which is what I've seen recommended for drains.

I'm saying that the fittings already had a pop rivet restrictor that in the past was known not to leak.

Ah okay, well. I ended up reusing the fitting with thirdgen's restrictor. Partially because I don't think he or I encountered any issues with it during use reil pressure. He also didn't have a leak with it so I think my fitting on the turbo itself was the issue. He's a bit of a nut when it comes to this stuff and I'm 100% that something not working in his setup would really **** him off. In any event, I think the .06 isn't really all that restricted compared to BB turbos.
The majority of the reason is the fitting I bought snapped in half when I was tightening the feed line to it... Not the bolt itself... the feed line. Must have sheared when I was snugging it up. Yuck. Luckily the oil feed hole was protected since it broke on the outside and that interface inside was in contact and above the break point.
I was going to paste a picture but the damn image uploader isn't working.

Maybe a built motor will happen around page 60 or so?
(Also that happened to Colipto. He blew a built motor that a shop had built for him. The second one seems to be doing far better!)

I know, I just wanted to say BOOSSSTTT because I took my car apart anticipating to install a new diff when a part arrived, and it's been like 2 weeks now and I still don't think they have shipped it.... So I miss boossssttttt. Your car is actually faster than mine since mine is on Jackstands!
