    Default Oil in Water

    The company owns a 2006 TATA Telcoline with 61 000km on the clock.

    During October 2012 we experienced that the radiator is filled with oil in a real gunk form and hardly any oil left in the sump.

    We took it to the dealers for repair.

    The dealers... "removed cylinder head and oil cooler, fit new oil cooler and cylinder head gasket, removed radiator and tank for cleaning and flushed the cooling system". They could not pinpoint the problem, but suspected that the cylinder head gasket collapsed.

    Beginning of December 2012 the exact same thing happed hardly 6 000km later.

    To date they have....." pressure tested the cooling system and found no problem, the oil cooler is 100% and the cylinder head gasket is fine.

    They now want to open the block as they believe that a sleeve may be cracked.

    I am ignorant because I cannot see how a cracked sleeve can allow OIL TO ENTER THE COOLING SYSTEM.

    Your thoughts on this.

    I must say I am with you on that one. If the pressure test was a success, then there is no way the coolant can get into the block or cylinder head? Was the pressure test done while the engine was on operating temp or cold?

    Hi Rofty,

    The pressure test was done while the engine was cold. Bear also in mind that the oil enters the cooling system and not water into the sump.

    Normally your sump is vented to atmosphere and your cooling system is under pressure(heat expansion in a close system), so for oil to entre the cooling system, boggles my mind
