RB20det smoke

[grnkouki]

like title states got a 96 with rb20 with a 25 turbo... it is now starting to emit smoke from the exhaust ..i have a S-AFCII installed .. any idea?

[rb25det250sx]

Blown turbo? what color smoke?

[grnkouki]

blue tinted white.... how much would it take to replace the seals, roughly, if thats the case? and any kind of "test" to narrow it down?

I forget what color oil burns again? could be the turbo or your rings.

oil = bluecoolant = whitefuel = black

Check you IC piping for oil.If you have a lot then chuck the Turbo and get something else.

Check for a lot of blow by.Compression test Check you pcv lines to see if there's a lot of oil and air coming out.

Leakdown test would be best
