Hey,
The drain pipe coming from the turbo is leaking in the seal connecting to the engine block and drooling all over the oil pan.

I know when you change the feed line is good practice to prime the turbo again so that the line is filled again with oil and doesn't deprive the turbo of oil for that little bit while running.

But the drain pipe supposedly doesn't have any pressure. What i don't know is...if i unplug it only from the engine block (again...the drain pipe), will it drain also a bit from the feed line? will i need to prime it again?

I'm guessing i can just unplug from the engine block, put in new seal, or use silicone, and connect it again and that's that. But i could be missing something, that's why i'm asking you.

Any help is appreciated, thank you.

Could you not just disconnect the crank sensor and spin it over for a few seconds to pump oil around the engine


The amount of air going through at starter speeds won't make the turbo spin fast enough to worry about
