Next I realized that the Blow-by Drain Tube was also a source of a Oil leak and that it looked like it had to be removed in order to change the O-ring. (Without the Turbo Drain removed I do not see how anyone could change the O-ring on the Blow-Drain Tube; no room.)

There is a Bracket under the Manifolds about midway on the Engine held with 2 17mm Nuts (one of which was rounded off, see pic).

There is also a 10mm Nut and Bolt in the Center of the Bracket (see pic yellow circle) that actually holds the Blow-by Drain to the Bracket.(In the pic I already removed the 10mm Bolt and nut and you see the hole where it was.)

Removing the 10mm ones may have given me enough room to change the O-ring but I wanted the whole bracket off as I had decided to modify the Air Filter and make a larger Blow-by Oil Separator.
So I had my first experience using an External Ezee-out to remove the 17mm nut and that went smoothly. (I had to remove the Tubocharger in order to use the External Ezee-out.)

After cleaning everything (The hole were the Lower Turbo Drain Tube goes was really cruddy) I found a Socket that fit inside of the Lower Turbo Drain Tube and was able to straighten out the dents that prying on the Clamp had made.

Install the Blow-by Drain O-ring and tube first or you will have difficulty getting the O-ring on.

On the Lower Turbo Drain Tube I slid the Grommet completely over the fat end of the Tube and installed both O-rings into their grooves. I greased the O-rings and the Grommet Lip and the tube area under the Grommet.

I inserted the Tube end into the hole in the upper Oil pan and pusned the Tube all the way to the bottom.

I slid the Grommet down but had trouble getting enough pressure on the Grommet to squeeze the lip in.
I found I could use a long handled Combination Wrench; lever and pull it down; and that worked.
(In the pic of this it does not look like there was enough room for me to use the Wrench to lever it down but there was.)

When installing the Upper Turbo Drain Tube (new Gasket securely glued on) I again had to find the “Sweet Spot” where it would fit and still clear the Lower Drain Tube. But, with that ¼ inch I ground off of the Bell End it was easier to get it over the Lower Drain Tube.

I was able to get the Turbo Drain Tube Bolts started by Hand from above and used the Box Wrench to tighten them.
I again used the 16mm Socket to slowly (so the Grommet stays put) push the Lower Drain Tube up further into the Bell of the Upper Drain Tube from below (I had not installed yet).

I did not have a new Oil Pan Gasket and used Silicone Sealant on the old Gasket and installed the Oil Pan. Added the Oil.

So far no Oil leaks from the work I did.
