Blown head gasket cause oil leak?

Answer 1

FINDING A RECENT POST MADE BY AN INEXPERIENCE PERSON MISLEADING THE PUBLIC, I NOW FEEL I MUST REMIND OTHERS THAT........

Blown head Gaskets are NOT BLOWN by the oil reservoir being filled to much. A high level of oil will NOT increase oil pressure.

An oil pump has a set amount of pressure allowed and no matter how much oil you over fill it, it will not increase pressure. It may make a mess or cause the engine to smoke BUT IT WILL NOT BLOW HEAD GASKETS.

A head gasket typically blows from an engine that is running overly hot and it's coolant has lost the ability to keep temperature below normal levels.

Loss of coolant. This causes an engine to get overly hot and expand to much. The two mating surfaces of the Engine Block and Cylinder Head where the gasket lays may expand away from each other and/ or the head itself may warp slightly causing the oil , coolant, or both to leak into each other or into the combustion chamber.

Some may think that if there is no water in the oil, or vice-a-verse then it can't be the head gasket. That can't be further than the truth.

The gasket keeps the OIL , the COOLANT, & the COMBUSTION CHAMBER separate from one another.

If an engine hasn't been properly maintained , like the oil changed regularly & the coolant system flushed & clean, it will develop contaminants and cause deterioration of the gasket. This will eventually cause a gasket to fail.

Because of the water jacket ( or ports) and the the combustion chamber being in such close proximity, a gasket failing between those two areas, will cause only the coolant to escape and it go into a combustion chamber. The coolant will immediately turn to steam and go out the exhaust without the driver knowing until it is to late.

During this phenomena, because the head is so extremely hot in the area of the exhaust valve , the sudden change in temperature from the coolant hitting the head may also cause the head to crack in a place where the metal is thinner.

The crack itself may then go across two areas of critical importance where a sudden change in engine performance alerts the driver of a problem.

The same applies to the oil jacket. It may leak into the combustion chamber but immediately will burn and cause a smoke to develop out the exhaust, giving warning.

Because both water & oil don't belong in the combustion chamber, the engine may start to misfire and/ or run poorly, giving a driver a false sense that a tune-up is all that may be needed.

It is important to regularly flush a coolant system & maintain clean oil and their levels to prevent catastrophic failure that can lead to thousands of dollars in repairs.

Answer 2

It can!, usually you'll see either blue smoke in the exhaust (indicating oil is getting into the cylinder and being burnt up with the gas) or white smoke in the exhaust (indicating that coolant is getting into the cylinder and getting burnt up), both which can be a sign of a blown head gasket, so look for those symptoms too!

Answer 3

white smoke out of tail pipe,radiator boils over

Answer 4

no it shouldn't but you will be losing water, and more than likely will be getting into the engine oil.

Answer 5

Normally it is caused by the engine overheating. Stuck thermostat, low of coolant, radiator clogged, and factory defect are causes.
