Does low compression and engine won't start mean a blown head gasket on a car that overheated?

If it was a head gasket then the compresion would be low in the affected cylinders low compresion as a result of wear wil make the car hard to start and overheating can also lead to electrical problems, Besides blowing a head gasket, overheating can also cause a cylinder head ro crack. Low compression and engine not starting or hard to start are symptoms. As mentioned above, do not discard the possibility of electrical problems due to overheating. However, the prime suspects are blown head gasket and/or cracked cylinder head.

2000 Mitsubishi galant ran hot and now won't start I was driving down the interstate and the car wouldn't pick up speed.. It slowed down and the engine shut off. What's wrong?
I would suspect you have blown a head gasket. Check for coolant in the oil. A compression test will verify if you indeed have a blown gasket. ==ANOTHER ANSWER== When an engine overheats you run the risk of causing serious damage. You'll need to run a compression test to find out if the head gasket has been blown. Overheating can result in a warped head which causes the gasket to fail. If you have low compression in any of the cylinders but especially any two adjacent cylinders, you will need to pull the head.
Can a head gasket be blown on an mgf It has not overheated and temperature is still normal but the oil is getting in to the water tank?
in a word yes when you turn the engine off theoil pressure drops quickly but the water pressure drops slowly so water will get into the sump then your crankshaft journals fail
What can cause the engine oil to overflow onto the spark plugs of a car engine?
possible bad valve guides or blown head gasket possible bad valve guides or blown headgasket
Why would a 95 Acura Legend have a lot of white smoke particularly when you take off after a stoplight but the temp gauge never fluctuates and it has never overheated?
White smoke is a sure sign that coolant is getting into your engine. This be caused by a number of things including a blown head gasket or a cracked head.
Watery engine oil?
Water in the oil pan ( looks milky or creamy on the dipstick ) is indicative of a blown head gasket. If your head gasket is blown you may have warped the head, especially if the vehicle was overheated. The fix is to remove the head(s) and take it ( or them ) to a automotive machine shop to be inspected and possibly milled. While the shop is at it they should inspect the valves and replace any that are bad. When you get the head back you will need to reinstall it with new gaskets. This is a good time to replace your timing belt or chain ( and tensioners ) since you will have the thing apart anyway. If you continue to run the engine in this condition you will do serious harm to the engine.
How do you find out if the head gasket is blown?
Have a compression test run on the engine.
What is the problem when you have the oil and water is not mixing in a vehicle that has overheated?
You probaby have a blown head gasket, cracked head or both. Try doing a compression test.
How do you know if it is a blown headgaskets?
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
How do you tell if head gasket is blown on F-250 Diesel?
A compression test will tell you if a head gasket is blown on ANY engine. Also, white smoke tells you that your burning anti-freeze, which means a head gasket is blown.
Your car overheated engine turned off and leaked oil and water?
Head Gasket blown, plus check your water pump.
What happens when the radiator hose bursts on a 99 Honda Accord?
If it burst because it was defective or just worn out and you did not continue to drive the engine until it overheated then no damage was done. However, if it burst because the engine overheated then you may have blown the head gasket, and you should have it looked at by a professional mechanic. Driving a car with a blown head gasket will do serious damage to the engine.
How do you know or how can you check to see if your engine is gone bad?
check for blown head gasket do a compression test
Car over heated and cut off now it wont start how can you fix this problem?
Run a compression test. If compression is down in several cylinders you've probably warped a head. That's a common problem after an engine has overheated, that's why it's so essential that you NEVER allow an engine to run out of coolant, and you should watch the temperature indicator. If an engine dies from being overheated you've probably blown a head gasket.
What will cause 4 cylinders in the same row of a v8 engine to lose compression?
Blown head gasket is one cause.
Why does coolant enter oil crankcase on Chevrolet pickup?
3 possibilities and none of them are good: 1. Blown head gasket (almost always caused by an overheated engine) 2. Cracked head (almost always caused by an overheated engine) 3. Cracked block (almost always caused by an overheated engine)
What caused an overheated engine?
Could be many things like a stuck thermostat, blown head gasket, warped heads, bad water pump etc.
Can you still drive with a blown head gasket?
If it is cracked, the vehichle may be driveable, but if it's blown, there's not going to be any cylinder compression and the engine won't run.
