T3s use a 1/8"NPT oil feed, T4/T04s use a 1/4"NPT.

do you think a -4 is too much oil? how do i know if im getting too much? one of my turbos looks like a little bit of oil is coming out the exhaust(open turbos right now). the turbos are new t4's but have been sitting in my room for a year. should i just rebuild it?

just a little dribble, not even enough to spray out. the other turbo did it for the first minute or 2 they were running, but its dry now, and the other turbo just started leaking, butthe truck hasnt ran for more than 5 minutes with the new motor yet.

Are the drains still angled like they are in your picture?
They should be a MAX of 30° from straight down, preferrably less. Even with a restriced supply, a clocked drain will cause them to leak past the seals.
-4 is fine on the feed, most turbos will internally limit the supply anyway. But if you have one without an internal orifice, you might need a flow restrictor. They only really need a few GPM of flow, and maybe 60 psi of feed pressure. Ball bearing need even less.
