0:00
you pull out your oil dipstick and
0:02
instead of clean oil you see a creamy
0:04
milkshake like mess uh-oh that's coolant
0:08
mixing with oil and it's a big problem
0:11
if ignored your engine could be on the
0:14
fast track to complete failure but don't
0:16
panic in this video I am going to
0:19
uncover five common causes of coolant
0:21
mix with oil and how you can fix it
0:24
before it's too late stick around till
0:27
end because I will also share a bonus
0:30
tip that will help to permanently fix
0:32
the coolant and oil mixing issue let's
0:35
get started first let's discuss the
0:37
function of coolant and engine oil
0:40
coolant and oil are like two co-workers
0:42
who should never mix one keeps your
0:45
engine cool the other keeps it
0:47
lubricated but when they do mix it means
0:50
something is seriously wrong here are
0:52
the most common reasons why coolant
0:54
Finds Its way into your oil reason
0:57
number one blown head gasket
1:00
a blown head gasket is one of the most
1:02
common culprits of coolant mixing with
1:05
oil the head gasket is a thin seal that
1:08
sits between your engine block and
1:10
cylinder head its function is to keep
1:12
oil and coolant in their separate paths
1:15
but when it fails all bets are off
1:18
coolant starts leaking into the oil
1:20
passages turning your engine oil into a
1:23
Milky disaster and here's the scary part
1:26
you might not even notice it at first
1:28
you'll see white smoke from the exhaust
1:31
overheating issues or even sludge under
1:34
your oil cap the longer you ignore it
1:37
the worse it gets leading to Total
1:39
engine failure to fix it you'll need to
1:42
replace the head gasket but fixing a
1:45
blown head gasket isn't a quick patch
1:48
job it requires serious engine
1:50
disassembly if that sounds like a
1:52
nightmare a mechanic can do it but
1:55
expect a bill of at least $1,000 or more
1:59
reason number two cracked cylinder head
2:03
now if you thought a blown head gasket
2:05
was bad this one's even worse a cracked
2:08
engine block or cylinder head is like a
2:11
death sentence for your engine
2:13
overheating or sudden temperature
2:15
changes can cause it to crack allowing
2:18
coolant to seep into the oil system a
2:21
cracked cylinder head can also lead to
2:23
poor engine performance rough idling and
2:26
overheating if you notice coolant loss
2:29
without any visible leaks a cracked head
2:32
might be the culprit pressure testing
2:34
and die testing can help pinpoint the
2:37
problem reason number three cracked or
2:40
warped engine block the engine block is
2:42
the core of your engine housing
2:45
cylinders pistons and oil passages if it
2:48
cracks coolant can leak into the oil
2:51
causing severe engine damage extreme
2:54
overheating is a common cause as
2:57
excessive heat can weaken and deform the
2:59
the metal freezing conditions can also
3:02
crack an engine block if coolant is not
3:04
properly mixed with anti-freeze a
3:07
cracked block can lead to coolant leaks
3:10
loss of compression and engine
3:12
misfires repairing it is extremely
3:15
expensive often requiring complete
3:17
engine replacement regular maintenance
3:21
proper coolant levels and avoiding
3:23
overheating can help prevent this costly
3:26
problem reason number four faulty oil
3:29
cooler many modern cars use an oil
3:32
cooler to regulate engine oil
3:34
temperature preventing it from getting
3:36
too hot under extreme conditions if the
3:39
internal seals of the cooler fail
3:41
coolant can mix with the oil leading to
3:44
contamination a faulty oil cooler can
3:47
also cause overheating and reduced oil
3:49
pressure which increases engine wear
3:52
signs of oil cooler failure include
3:54
milky oil overheating and visible leaks
3:57
around the cooler replace ing the oil
4:00
cooler and flushing the oil system is
4:02
necessary to prevent long-term damage
4:05
regular maintenance and using
4:07
highquality oil can help prolong the
4:09
life of the oil cooler and prevent
4:12
failures reason number five overheating
4:16
overheating is one of the main causes of
4:18
coolant mixing with oil as excessive
4:20
heat can warp engine components causing
4:23
gaskets to fail and cracks to form
4:26
running the engine with low coolant
4:28
levels a failing water pump or a clogged
4:31
radiator can all lead to overheating
4:34
when metal Parts expand due to high
4:36
temperatures they can lose their seal
4:38
allowing coolant and oil to mix to
4:41
prevent overheating regularly check
4:44
coolant levels and engine oil ensure the
4:47
radiator and thermostat are functioning
4:49
properly and address any cooling system
4:53
immediately so you've found the leak and
4:56
fixed the problem great but your job
4:59
isn't done yet that milky sludge in your
5:02
oil pan is toxic for your engine and you
5:05
need to flush it out completely first
5:08
drain all the contaminated oil and
5:10
replace the oil filter then fill the
5:13
engine with fresh oil and let it run for
5:16
a few minutes after that drain it again
5:19
and do a second oil change to make sure
5:21
every last bit of that Gunk is gone and
5:25
don't forget the coolant system flush
5:27
out the contaminated coolant reach fill
5:30
with fresh anti-freeze and you're good
