DETROIT — General Motors Corp. announced Monday it will pay to replace
the head gaskets in up to 500,000 1987 - 1991 vehicles equipped with four - cylinder Quad 4 engines, a program that could cost the automaker $ 275 million.
(I've fully described
a head gasket in this answer.)

in CA
in December.
The worst of this 4 - 6 quartet is the Miami Dolphins — their
head coach, Adam Gase, blows childish
gaskets every five minutes while orchestrating a team that often plays
in similar, infantile fashion.
A failing
head gasket might also be leaking oil out of the block, which could explain a large loss of oil without an equal gain
in the coolant level.
In the case where you run it too hot, you could start messing up your
head gasket or warping the
head itself.
In the meantime, here's a relevant question on how to test for a bad
head gasket, as that's a possibility here.
But I suppose it would also be possible that while idling a normal reduction
in coolant flow could allow a small
head gasket leak to display coolant that would be replaced, or mitigated, when the engine speed caused more vigorous circulation to resume.
I took off the valve cover to replace the
gasket and noticed that there was quite a bit of oil puddled
in the cylinder
head.
Can you explain how running a lower octane
in the absents of spark knock causes
head gasket damage?
The car is not really exhibiting the classic signs of a blown
head gasket (blue smoke, coolant
in oil etc), which is part of what makes this a puzzle.
Your problem, like you said, could be the cooler, a
head gasket leak, or a crack somewhere... I would put them
in this order of probability, though.
One is at the
head gasket where oil can leak across the top of the
head to the water passages (or into the cylinder or out the edge of the
gasket) if the
head isn't properly torqued of perhaps if there is corrosion
in the cooling system.
What looks and acts like a blown
head gasket, resulting
in coolant
in the cylinder, when the
head gasket is fine?
My guess is going to be a problem with your
head gasket or some crack or warping
in the
head.
Overheating causing blown
head gasket: as indicated
in other answers, severe and prolonged overheating can cause the engine block to warp, meaning your
head gasket won't seal properly anymore.
The
head gasket between the crankcase and the cylinder
head could show weakness as the differing expansion expands one component a bit more than the other and over time weaken adhesion between the two surfaces resulting
in a failure.
In no way does the symptoms scream
head gasket to me.
Here's an example using a scope, this came
in after a
head gasket replacement and you can see the balancer is slightly off.
Oil
in the coolant can foul the temp sensor, which would also be a sign of a bad
head gasket.
And to think of all those Offy Indy engines and Testa Fissa Alfas
in which the block and
head were one piece to prevent blown
head gaskets.
water flowing into
head and boiling cause
gaskets stuffed between cylinders a bottle of chemiweld there are others it works best fixes that
in moments.
If milk - like oil ends up
in the radiator despite replacing the
head gasket, it is likely that the
head itself has warped due to overheating, allowing oil to leak into the coolant channels.
You can test your rings and
head gasket with a leak down tester Checking your spark plugs as shown
in @Zaid's post is the first order of business.
You would be talking adding lot more water
in the mix to even have any adverse affects (blown
head gasket and such), than just a little bit of humidity which would most likely evaporate at running temperature anyway.
You can do a compression test to check for
head gasket failure, which involves removing each spark plug
in turn and replacing it with a gauge that reads the amount of compression
in the cylinder - if the
head gasket is blown, one or two will be well below the others.
I feel like I wasn't confident enough of the combustion gases
in the block were of a sufficient volume for a small
head gasket leak that we suspected.

As with pressure, this includes pipes,
gaskets etc., but also the types of metal used
in the cylinder
head, pistons themselves and the exhaust.
White smoke from the exhaust when started tends to point to a failed
head gasket, causing coolant to burn
in the cylinders.
Extreme temperatures lead to warped
heads which will
in turn lead to a blown
gasket.
In the end the mechanic discovered it was caused by bad oil, it was not head gasket problem, just clogged drain on the front end of the engine and nearly clogged in the bac

In most cases, if you have a blown
head gasket, you'll be losing coolant.
I think it's Block Seal
Head Gasket Fix... Instant headgasket
in an easy - pour can.
While this cracking may still be caused by regular vibrations I am wondering if blown
head gasket may have actually caused periodic pressure fluctuations
in the cooling system and that somehow contributed to the coolant reservoir wall fatigue.
If you consistently ignite the fuel a little too early, you'll blow holes
in your pistons, break piston rings, break connecting rods, shatter crankshafts, blow
head gaskets, etc..
If these areas are not clean, it can lead to hot spots
in the cylinder, and a poorly sealing
head gasket.
Like you said THE COOLANT MUST BE GOING SOMEWHERE and it's not on the passenger floorboard or the ground so it's being eaten up somewhere
in the engine (
head gasket).
Check the
gasket between cylinder
head and cylinder block becoz bad
gasket can cause leakge of oil as well as coolent also and both can come
in cylinder bore....
I would have never put
in a new radiator if I'd known the real problem was the
head gasket.
Sometimes catastrophic
head failures don't contaminate the oil (which does indeed produce a frothy substance as you describe); the
head could be cracked from the outside into a coolant passage, or, rarely and usually only
in poorly manufactured or improperly installed
gaskets, the
head gasket can blow outward from a coolant passage.
This results
in a low coolant level, so is that why it is overheating or is that a result of a
head gasket?
You can get a relatively cheap kit to test for exhaust gases
in the coolant (or any number of other methods to test the
head gasket.)
I recently did a
head gasket repair on my 1986 Kawasaki GPZ1000RX and now that everything is back together it starts up fine, idles fine, and revs high without a problem while
in neutral, but when I put it into gear and started driving it it'll drive fine when giving it slight throttle, but when I get to the higher revs, or when I open the throttle too quickly it bogs down badly, and starts stuttering, but eventually starts revving higher and leveling out.
I've seen different descriptions to there may be a metal
gasket in between the pump and the
head and some pictures show two rubber or viton seals that may be inside the pump.
Lastly, oil
in the reservoir is also an indication of possible bad
head gaskets and / or other things.
Oil
in the coolant is often indicative of a blown
head gasket, but there are many other reasons why it would happen.
It either goes on the ground (external leak),
in the passenger floorboard (heater core),
in the engine oil (
head gasket), gets burned up (
head gasket, or possibly intake
gasket), boils off, or it stays put.
If there is oil
in the coolant (looks like mud or creamy mayo) this usually indicates issues with the
head gasket and / or cylinder
head.
