Not sure if anyone can help me out but here goes.
Astra 1.6 ecotec, z16xe engine, 02 plate.
Was smoking and stinking of oil so i changed the piston rings, changed valve guides, changed valve stem oil seals, fitted new big ends and main bearings, re-seated the valves but yet the car is still the same, light grey smoke!
From start up there is a little blue smoke but if i leave it to idle for a few minutes then give it a rev, i get massive amounts of white/light grey smoke. it doesnt use any water and it doesnt seem to be dropping any oil on the dipstick.
Its wrecking my head now so if anyone can bring up anything i may have missed??
