that is straight forward sufficient to respond to, you maximum in all probability have a blown head gasket, i could examine the oil for antifreeze too just to make particular (you will understand if there is antifreeze in the oil no rely if that is milky in visual charm). If there is not any antifreeze in the oil, then i could initiate by ability of flushing your cooling device first to work out if the concern reoccurs, if it does, or if there is antifreeze in the oil, then its actual the top gasket, or it might desire to be a cracked head or block too, yet maximum in all probability the gasket. If there is antifreeze in the oil, or if the concern reoccurs after a flush, do no longer tension the automobile till that is repaired as you may reason extra severe engine injury then you relatively have already got and land up junking the automobile or changing the engine completely. thank you Gregg for pointing that out, might desire to be the intake gaskets too, even nonetheless I even have considered Head gaskets circulate in this very engine in the previous so i does no longer rule it out. yet changing the top gaskets nevertheless demands changing the intake gaskets anyhow, and pondering the concern It wont harm to interchange the two and which will provide probability to ascertain the heads and block for cracks besides. additionally, Gregg is sturdy on the gaskets, actual decide for the metallic ones, in case you utilize the cheap plastic ones, you would be tearing it down lower back very immediately.
