Blue smoke at idle
As alot of u know my car is turbo and ever since I turbo it, when I first turn on the car n I let it idle for a little n then I hit the throttle blue smoke comes out the exhaust n I'm running a new turbo, -4 with a -3 restritor feedline and a -10 return line and I'm running 10w-30 and I can't figure out what it is. If anyone knows what it could be plz help thank you

mmm.... blue smoke means you're burning oil I believe....
Symptom: Gray or blue smoke from the exhaust. You notice smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it.
Possible causes:
1. The engine's piston rings may be worn.
The Fix: Replace piston rings. (Generally not a DIY job)
2. The engine's valve seals may be worn.
The Fix: Replace valve seals. (Generally not a DIY job)
3. Damaged or worn valve guides.
The Fix: Replace valve guides. (Not a DIY job)

Is your oil return line fitting above the level of oil in the pan, and does it run smoothly from the drain on the turbo to the pan with no crazy bends? Also, is the flow completely downwards the whole path?

I am having the same problem. lol. my engine is fine, its the turbo thats my problem for sure, as my plugs are clean and compression is where it always is for me.
I run a -4 feed and -8 drain.
I am feeding with a -4 line ot this:

no restrictor being used, so oil can really pour in.. to much oil?

-4 is a pretty big feed line, and -8 is definitely too small of a drain line. At a minimum you need a -10 drain line, but I would go for a -12.
I use a -3 feed on my Integra and a -12 for the drain if I remember correctly. I have an MHI EVO III 16g so it is not ball bearing, but it does contain an internal restictor built into the housing.
