a head gasket is part of an IC engine
0:02
that provides a seal between the
0:04
cylinder head and engine block
0:07
the main function of the engine head
0:09
gasket is to stop the leakage of engine
0:11
oil or coolant into the combustion
0:13
chamber and seals the combusted gases
0:19
the head gaskets allow the vehicle
0:22
engine to generate adequate energy to
0:24
move the vehicle as well as direct the
0:26
toxic gases through the exhaust system
0:28
and stop them from leaving the
0:32
the blown head gasket occurs due to the
0:35
seal failure between the engine block
0:41
causes of a blown head gasket
0:47
1. engine overheating
0:53
an overheated engine is one of the major
0:56
causes of a blown head gasket
0:59
the manufacturer of your car fixes the
1:02
highest heat bearing capacity of the
1:05
as this heat exceeds the normal level
1:11
your head gasket is damaged due to
1:13
overheating because extreme heat can
1:15
cause the cylinder head and engine block
1:17
to expand too much which can cause the
1:20
cylinder head gaskets to fail
1:25
2. age of the head gasket
1:31
over time the Seal of your head gaskets
1:34
can damage and may not function properly
1:36
to stop leaks and other issues
1:40
the ultimate age of a gasket is written
1:42
on your vehicle's manufacturer's
1:46
you must replace it according to the
1:48
manufacturer's instructions before
1:50
facing any big trouble
1:56
3. pre-ignition or detonation
2:02
the pre-ignition or detonation is an
2:05
abnormal combustion condition that puts
2:07
excessive pressure on the engine's
2:11
detonation occurs when the air fuel
2:13
mixture in the engine's combustion
2:15
chamber explodes in more than one place
2:19
this can create a knocking sound and a
2:21
lot of pressure which can damage the
2:28
4. excessive engine load
2:34
this issue can occur if your car is
2:36
designed to tow heavy loads regularly
2:38
particularly if it's not manufactured
2:43
The increased heat and pressure May
2:45
strain the head gasket causing it to go
2:51
5. poor engine management
2:58
poor engine management includes problems
3:00
such as using the wrong engine oil uses
3:03
of the wrong fuel type or improper
3:07
any of these May produce situations that
3:10
can force the head gasket to blow
3:16
6. incorrect coolant mixture
3:22
if the coolant mixture is not correct it
3:25
can lead to corrosion or erosion of the
3:31
too much water in the mix can cause
3:33
corrosion while too much antifreeze can
3:41
7. improper ignition timing
3:47
if the ignition timing is not set
3:49
correctly it can cause the engine to run
3:52
hotter than it should which can lead to
3:59
symptoms of a blown head gasket
4:05
1. engine overheating
4:11
engine overheating is one of the clear
4:13
symptoms of a damaged head gasket
4:16
the gasket is a part of the engine that
4:19
keeps your engine cool by circulating
4:21
oil and coolant throughout the engine
4:24
as your engine cylinder gasket fails or
4:27
is blown the engine couldn't properly
4:29
circulate oil and coolant through the
4:41
when the head gasket is blown the
4:43
compressed air and fuel mixture starts
4:45
to escape from the engine cylinder and
4:48
the compression pressure of that
4:51
due to insufficient compression pressure
4:54
the engine won't produce sufficient
4:56
power to run a vehicle and the engine
4:58
will move poorly and idle roughly
5:02
As You observe such symptoms in your
5:04
vehicle engine this may be due to a
5:06
blown head gasket and you need to
5:13
3. white smoke from the exhaust
5:20
your engine's gasket regulates the
5:22
proper flow of the coolant throughout
5:23
the engine and stops it from entering in
5:25
the combustion chamber
5:28
as the head gasket is blown or fails the
5:31
coolant starts to enter the combustion
5:33
chamber where it mixes with fuel and
5:35
burns due to the burning of the coolant
5:39
in such case the engine starts to
5:41
produce gray or white colored smoke and
5:44
emits it from the tailpipe
5:49
4. contaminated engine oil
5:56
the head gasket stops the coolant from
6:00
as it is failed ore is blown the coolant
6:03
starts to enter the engine oil system
6:05
and try to mix with it
6:08
as you know coolant and oil can't mix
6:13
therefore when the coolant enters the
6:16
oil system a frothy thick mixture starts
6:19
to collect below the oil filler cap of
6:31
as your engine's head gasket is blown it
6:34
won't stop the coolant from entering the
6:39
due to this the combustion chamber will
6:41
start to consume coolant
6:44
due to low coolant the vehicle engine
6:49
because of the engine overheating your
6:52
car will start to show a temperature
6:56
this overheating problem may be due to
7:00
in such a situation you need to inspect
7:03
and replace the gasket immediately
7:09
6 bubbles in the radiator
7:15
if the combustion gases start to enter
7:18
the cooling system bubbles may start to
7:20
produce in the coolant overflow tank or
7:23
radiator even if your engine is still
