How do you know if drain line is working?
I did some searching but I couldn't find anything on this topic. I recently installed my turbo and I had to custom make my oil lines. For the drain line I have a 20" line with -8an fittings. The turbo is a TD05 and coming off the turbo i have a 1/2" NPT to -8an fitting. In the oil pan I have a 3/8" NPT to -8an.
The turbo is oil and water cooled. It doesn't make noise but then again I have only had it on the car for a few days.
My concern is that the -8an fittings are too restrictive but according to the links below, 3/8" NPT is fine.

When I was looking at the fittings before the install, the 3/8" NPT looked to be the same size opening as the -8an so I figured it would be safe but I just want to hear your opinions.
BTW the car is a 99 making 8psi but I intend to bump it up to 10psi eventually.

So you are not worried that it *isn't flowing* you are worried if it is flowing enough? Honestly with the pieces you describe above there should be no flow issues. -8an is 1/2" OD, so I'm guessing probably 3/8 ID or close.
