Leaking vcooling system possibly? replacement of head gasket?
I have taken my Ford Focus 2001 to the bodyshop today as the engine warning light was on and the car was mis firing, and almost stalling when stationary. The bodyshop took out the plugs which were full of water?. They seem to think that it is a build up over time and that there could possible be a leak in the cooling system?. They have cleared out the water and the car is running ok again, light out. They suspect that over next few days the problem will reoccur. They suggested trying a sealant fisrt over the head gasket and this should seal the core plug... if this is what is leaking. Otherwise it will mean removing the engine and fixing/replacing the head gasket which I know is a huge and expensive jo? more to the point would it be worth it for a car of that age (Y) reg? Any ideas???? please??

Re: Leaking vcooling system possibly? replacement of head...
First thing i have never seen a sealent that would fix a bad head gasget, secound if you got water in the cyl. than most likely there is water in the oil witch over a short period in time will do damage to the vitals in the bottom end. Third for them to tell you that a sealent might fix the leak i would be getting a secound openion.

You have either a bad head gasket that needs to be replaced ASAP or possibly a cracked head (more expensive). If you continue to drive or run the engine it will suffer crankshaft bearing failure. If the intake manifold is a "wet" type (coolant goes through it for any reason) that gasket may be leaking and letting water in the oil. But I'm leaning toward a new head gasket.
In either case, water is entering the combustion chamber.
Header gaskets are fairly expensive to replace. It depends on the labor rates of the repair facility. I would try to find a local community college that has an automotive degree program. Usually they will charge much less for the fix (to help students learn) than a garage. If that isn't an option I would replace the head gasket and not the whole engine. Of course, if there is other damaged caused by the leaky gasket that is another story. There is a lot of labor involved with replacing a header gasket. I would say anywhere from $500 to $1000 anyway. Hope this helps.
check manual compression in that cyl. then check one thats not missing you will probably find compression low or none in cyl 2 could be valves in the head stuck open, bent, cracked head or head gasket leaking into cyl 2 or possibly in the lower end crankcase. i would def.check compression first before anything else...
What happening is you have a bad head gasket or its starting to go bad. As long a little oil is getting in to cylinders causing that smoke once it warms up that gasket is expanding thus the smoke stops. I would keep an eye on oil levels if it gets milky replace gasket asap. Could also be intake gasket but highly doubt it this sounds like a worn head gasket.
there could be a number of reasons
1 if you just toped it up you could have air in the system
2 the cooling fan may not be working
3 the termastat is no longer operating ( they normally fail open )
4 the coolant is old or contaiminated and needs changing
5 a leaking head gasket ( you exhaust will smell sweet and look white in color
6 a blockage in the engine passages the coolant flows
I doubt its the instrument cluster. Next time it does it, turn the heaters on full hot. If the air is very hot, you could be looking at a thermostat problem. If the air is cold, then you are either losing water or your waterpump is on its way out. However waterpumps dont tend to be sporradic, so i would go for water leaking.
