hi i think my valve guides are worn on my sapph 2wd cos its smokes when i back off then when in traffic the turbo has done 4000 miles since fitting and also rebuilt bottom end with new rings etc changed valve stem seals any ideas????????

 

what breathers system you got standard or after market? what's the spec of the engine? what oil u using?all these could be a factor to your problems.

 

its stage 3 t34stage 2 hybrid dark greens 3 bar group a actuator and group a breather. it smokes when i back and back on again
