2.0 8v over revving and smoke comming from breather pipes

[rob hope]

hi. i have just fitted a 2.0 8v engine into my clio i have started it up and it is revving up straight away and there is also smoke coming from the breather pipes can any 1 help point me in the right direction of what the problem is thanks

how high is it revving mate? how much smoke coming out the breathers?

 

[rob hope]

not much smoke but theres no pressure so it barely comes out. its as if the throttle is wide open all th time when its not if tht makes sense

 

[Russ_16v]

so it revs flat out when its started? what throttle position do you have? is the butterfly fully closed?

 

[rob hope]

yea the butterfly is fully closed mate

 

[Russ_16v]

well its sucking in air from somewhere badly, the breathers are supposed to have some fumes in but not black smoke, id say at a stab in the dark possibly piston ring wear, causing too much crankcase pressure, would explain the smoking breathers

thanks for the info mate grately appreciated al strip the engine down and see wat i find. thanks agen
