Just to clarify for the thread so this doesn't become a "installation error or greasing error or user error thing " I have not even opened the grease, grease gun or grease gun hose. I have not greased this turbo yet and the zerk fitting just fell out at some point in time just driving the car.

I'm just giving you a heads up on greasing.

A press fit zerk fitting is not screwed into place. As there are no threads. So there are no torque specs. You have to either press them in, or beat them in. I have used a socket, extension and a hammer to tap them in place.

Problem you may have is a slightly bigger hole then what is called for. Or the zerk was undersized. One is the reason why the zerk fell out.

The zerk is threaded into the stem, and the stem is threaded into the center section. Nothing is pressed in.

OP, I will check with COMP on the torque spec, and other things mentioned.

I understand that this may have fallen out at some point during operation, which is not right.

I will make a suggestion to have these threaded in as well.

I was going by on what you had said earlier. About them being pressed in. And no threads in the hole.

Yup... I assumed wrong

First time this year that I have been wrong...had to happen eventually.

You're excused.

Would anyone else be concerned that their turbo wouldn't be sufficiently lubricated if this happened to them or am I crazy for thinking this, wouldn't it be equivalent or close to running a oiled turbo without the oil lines connected?
