    Hello, gentlemen, I need advice. I did a head overhaul, burned out the valve, replaced all the valves, a whole set of new sealants, a new head gasket, new timing, tensioner, chain, gears, guides, new collector seals are known. The effect, after assembly, the engine works very well, clean and quiet. The problem is that before renovation, it took oil as standard, i.e. about 0.4 liters per 1000 km, after firing it takes 1.5 liters per 500 km. Anyone knows what else might have happened, please help. I excluded the rings because previous wear did not indicate the need to replace them. Best regards and waiting for some info.

    Hello.
    1.5L of oil per 500 km is far too much for the engine. u In this case, either you have a leaky oil system and somewhere there is a leakage or else oil gets into the combustion chamber. You should drive to a diagnostic station and check the exhaust gas composition. Is the fuel consumption at a normal level?

    All this will be checked, I am thinking only about the clogged pneumothorax because the suction manifold was very heavily soiled with something like a tawotka, but only to the throttle. From the throttle to the air filter clean.

    The rings can be checked - check the compression on a warm engine in all 4 cylinders, then pour 4 cm3 of engine oil into each cylinder and take a measurement. If on the first measurement it was weak or uneven and in the second measurement it improved 100% of the wine's rings

    Checking the compilation will do nothing.
    Compression will be.
    The oil ring and piston tubing are baked.
    Everything beautifully described on the forums as above.

    I have this method, engine, I bring the whole car from England with known mileage.
    I haven't driven yet. The oil intake stops, so there's something to it.

    And burying and REPAIR of this thing is pointless because you have to spend about 30rbh and about PLN 2,000 on parts and machining.

    It is often the case with a heavy-duty engine that when the top is sealed, oil begins to pull through the rings. In my opinion, in older cars doing the top is pointless. Especially if someone changed the oil according to the manufacturer's instructions. The rings are almost always baked.

Topic summary

The discussion revolves around an oil consumption issue in a Volvo engine equipped with a Ford 1.8 BE engine after a head overhaul and valve replacement. The user reports a significant increase in oil consumption from 0.4 liters per 1000 km to 1.5 liters per 500 km post-repair. Responses suggest potential causes including oil leaks, oil entering the combustion chamber, and issues with piston rings. Recommendations include checking the exhaust gas composition, inspecting the oil system for leaks, and performing a compression test to assess the condition of the piston rings. The consensus indicates that the rings may be baked and require replacement, as this is a common problem in these engines.
