    Astra Sport 1.6 engine smoke and rattl

    Hello everyone,

    My astra sport 1.6 16v had a new head gasket at 80000 and has smoked slightly since however lately the smoke (white) has got worse and my oil seems to have all gone (leaked from head). I dont understand because i am not loosing coolant, however it is a brown colour. Engine also rattles or taps which seems to be inside the head. I have no idea what is wrong just cant work it out, new engine maybe? Can anyone help as if cant be fixed will be scrapping/changing engine. Thanks

    White smoke can be oil being burnt in the piston - brown coolant isn't right, it should stay pink (or blue if you use blue coolant) unless the system is mucky.

    Rattle could be piston rings or crank bearings/journals/cam bearings. Tapping can be valve lifters or can be a small hole or leak in a gasket or manifold.

    Difficult call really! After trying a second hand engine, I ended up having my original rebuilt, but I had a good price on the work from a member on here who was local-ish. Without that, a commercial price on the actual labour of stripping/rebuilding/refitting would have been way too high.

    i'd be very carefull my brother had the astra before me and hit the sump loosing all the oil and his stated tapping a few days later and piston 1 failed wrecking the engine

    i stripped it down and piston 1 had disintergrated con rod bent no sign of the shims but the con rod bolts snapped but the bit of bolts left in the conrod ones shorter than the other . so my guess is one of the bolts came loose with no oil then eventually snapped so go get it checked asap

    i may have a video on my phone or on my partners phone if i still have it ill post it up for you to compare noises
