Howdy!!!

I have a suspicion it may be valve guide seals. Had this with me Integrale - same motor!!

Thats the next guess for me too, does it do the smoke when you "lift off" the gas?

Or, is it perhaps overfuelling on idle?

It cant be the seals because I changed the last week and the engine is not leaking any oil. Thats why Im very curious of what the problem might be.

Either that or you've a leaking piston ring ... although i think it's more likely to be a Valve guide seal that isn't !

I dont think it has any to do with the valve seals since the engine in my car is rebuilt so I had to buy every seal new and the piston are also new.. Just recently I did 500km with my new engine but Im not using it right now because of that problem.

You say the fuel concumption has increased..... if this is the case the engine may be running very rich... I.E injecting too much fuel which subsequently isn't burning properly causing the excess smoke ( check out any old Ford with a carburettor and you'll see the excess smoke, although some burn oil too!)

The colour of the smoke is supposed to point to the problem:
White - water getting into the system, head gasket.
Black - excess or rich fuel, injection system
Blue - oil burnt, piston rings, cracked valves, etc.

my first question is what colour is the smoke.??

are you sure of the quality of the turbo rebuild.?

where the guides fitted properly i.e not split when fitted.?

it could be a broken oil control ring(piston).!
worn bores.!broken when fitted.!!

or as simple as a blocked breather pipe.!

also is there too much oil in it.!?
