Rb25Det Blown Seal/gasket

[Crazy Xav]

Hey all, Ive searched through many pages and still haven't found the info I was after.

I have a 1993 R33 GTS25T, basic bolt ons.

it still has the standard turbo that has been hiflowed.

its developed a problem all of a sudden, there is smoke coming from the turbo area, not from the manifold/head, instantly I thought i blown a seal but generally that would cause smoke out the exhaust too, there is no smoke what so ever from the rear.

Also there didn't seem to be any power loss, boost problems etc.

Have removed the turbo to inspect and it all seems tidy and healthy, no shaft play no scorching etc.

wondering if anyone else has/had problems similar and what it was.

Cheers!

Could it be your R/C gasket leaking onto the exhaust manifold causing the smoke? Maybe the turbo oil feed lines was weeping?

It was the exhaust manifold gasket, the tick just hadn't made itself audible at the time.

I will be sure to double check what you suggested when she goes back together (+ new manifold, turbo and braided lines)
