blue smoke on exhaust after fitting a single

Sounds like turbo shaft seals. Could possibly be valve stem seals, but it would almost certainly have shown this before the turbo change.

 

Ask them in writing if the turbo is made in the USA or the far east (probably China?), and see what they say, I am sorry to say I would think your issues are a turbo one.

 

Based on the price of the turbo I'd guess it's a rebranded Chinese made one.

so here are the news

i dissassemble all to locate my problem

 

so what i see

1) no blue smoke on start

2) blue smoke comes after one or two minutes and pulls off the exhaust every time i put the feet on the accel pedal

3) no oil at all in the intake

4) no oil at all in the fmic piping

5) when i remove the two littles hoses from the cam covers, no smokes coming from it

6)the hot side of the turbo is full of oil (pic 1)

7) there 's a sort of a protection just the rear of the exhaust wheel and it's moving (pic 2)

so for me it's or a dead turbo or valve steam seals thats have been destroyed

Thats your turbo oil seals bud - if the exhaust housing is 'wet' then the seals have gone and oil is leaking into your turbo and coming out of your exhaust as blue smoke

 

You can either get the seals replaced or get a new tubby - personally I would go back to OBX and say the seals are buggered and see what they say

you're right about the turbo...

i just remove the hotside to look into the manifold.

Not a penny of oil into it

and when i look into the hotside, i can see taht the oil leak began near the compressor wheel
