I've been having some trouble finding an up to date listing with a restrictor size (and link to purchase).
I'm currently running no restrictor and I'm getting some oil in the intake.
Id appreciate some help just getting the right size and thread of the fitting.

Or get a pop rivet where the shaft measures 1.5mm in diameter. Spend 2 cents, remove shaft, install.

 

I just used this braided line and didn't have any issues with my T25.

Maybe it's because your oil pressure was lower than mine? I'm running mobil 1 0w-40. It's possible that my higher oil pressure is causing the pop rivet to not be enough to reduce pressure?

Byte's turbo is leaking exactly where mine is lol.

 

plenty of restrictor fittings on ebay

depending on the size of your oil feed line you need -3AN or -4AN restrictor fitting

what makes you think you have higher oil pressure?

 

I don't actually think it's too high, but gets up in the 60s which isn't crazy from what I've read. I don't have smoke out the exhaust so it would be strange if this was a pressure issue.

Todd didn't have this leak when he used the turbo and byte didn't have the issue with his older turbos.

So either it's a pressure issue or a drain size issue. From Garretts site, they expect those to be the issue before the turbo itself. That's also for new turbos though.

I'm just casting a wide net so I can systematically approach this.
