It depends -- I drove a chevy station wagon from Pennsylvania to northern Minnesota with a badly leaking head gasket and still drove it thereafter by having to constantly fill the radiator with water. You could try a cooling system sealant if you are leaking a lot of water and an engine oil sealant would possibly help to extend its longevity.

Keep looking for a better price along the way -- it is a straightforward repair, you just have to remove a lot of parts to get at it.

2002 Subaru outback is leaking antifreeze and not heating up.

This is common issue early sign head gaskets failure for EJ251 SOHC engine for external coolant leak. Second gen 96-99 with EJ25D is worst because when head gaskets failed, it's an internal leak that allows coolant and oil mix together in the combustion chamber to destroy engine.
You can drive it for at least 6 months or more as long as you keep top up coolant since the leak should be small at a slower rate leak. I drove mine for a while before change head gaskets. You're looking at `$1000-1200 job a dealership since you might as well change the timing belt, water pump, idlers while engine is pulled to replace head gaskets.

Water and steam from side of engine near coil pack

- Could possibly be worn or blown head gasket. Cracked head worst case. Pretty expensive fix either way if taken to a shop or dealer, but can be taken care of. If driven too long or hard, seal or head could fail further mixing your coolant, oil and gas causing serious damage to your engine.
- Best case, check your freeze plugs, one or more may need replacing. They are pretty cheap and fairly easy to replace, and can be acquired at your local auto parts store.
- To prevent future problems with this, you can take precautions by replacing your thermostat, changing coolants to 50/50 anti-freeze, and flushing your radiator. I would NEVER use stop-leak, as it may fix leaks with your radiator and/or other components, but can cause other blockages internally inside your engine. Also, check your hoses for cracks and pinholes or leaks. Hope this fixes your problem.

1997 Nissan 300x, mechanic said exhaust leaking into cooling system and needs replacement engine. Any other things to check before doing that?

The cylinder head gasket or a cracked cylinde rhead or heads can cause this problem, a new engine is not required to fix these problems, just new gaskets for heads or rebuilt heads. Cost about $1200 worst case.

The "Check Coolant Level" light

no heat to the interior of the car indicates a closed thermostat-the coolant level warning is controlled by the sensor in the surge tank, it is either disconnected or malfunctioning. cleaning the tank itself can sometimes get it working again, or look for another in a local junkyard (much less expensive than the dealer). Your overheating can very well be due to the thermostat, so changing it might solve a couple of problems-and the Northstar engines do have head gasket problems due to streaching head bolts that also damage threads, a permanent repair is to replace the head bolts with 'timesert' :

Leaking antifreeze, have been told it could be head gaskets.

Hello roxanna surf: My name is Roger and I will help you. The problem could be one of several problems. GM has a problem with the intake manifold gaskets leaking coolant useually external but can leak internal also. Check at the corners of the intake manifold where the manifold meets the heads. If you see green or orange drops of coolant or a slimmy build up than the intake manifold gasket is leaking. Idf the leak has been ongoing for some time and the engine has overheatedI would also look at a head gasket, warpped head or even a cracked head as a source of the problem. The engine does not like extreme heat and can have serious issues. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

When i put my car in drive and let off the brake the car will take off without me even pushing the gas pedal. it will go from first to second with no foot on the gas.

you probably have a intake manifold gasket leak,,this casues a vacum leak at number 1 cylinder between the intake manifold and the cylinder head the gasket collapses and leaks air this sucking more air into the engine a giving it a high idle like 1200 rpms or more sometimes and this will cause you issue,,,its a typicial issue for the SL1 abd SC1,,,gaskets about $12 at autozone about $40 at dealer and about 5 hours labor to change it,,but thats your issue,,,eventualy it will set a high idle code with the ses light

Starting problem

Sounds like the garage didn't do something correctly.

Apparently heads are a serious problem for BMW.

Here's a brief history and an unofficial description of BMW's position on their head problems:

Here's a step-by-step on the Timing Case ProfileGasket (aka, the head gasket) replacement for reference so you can see what should have been done:

However, the good news is that the difficulty starting and the fuel leak may be just the result of a clumsy re-assembly in fuel delivery bar. Check out:

Now doesn't replacing a few O-rings sound better than having to tear the head off again? :-)

2000 chevy impala ls - oil spray under hood inline with serpentine belt

You may have a lower intake manifold gasket leak (or a head gasket leak-slightly less probable) the lower intake can leak onto the serpentine belt and fling oil (and/or antifreeze). The lower intake manifold gasket is usually the culprit here. There is much information about changing it if you are inclined to do it yourself. If not, expect around 800 to 1200 to fix at dealer/mechanic. This is usually accompanied by (but not always) oil in the antifreeze, or antifreeze in the oil...
