It’s Bad When You Have a Blown Gasket
Saturday, February 20th, 2010It can be a really scary thing when you start your Ford Expedition in the morning and billows of smoke come pouring out of the tailpipe. It is only worse if there is also a puddle of oil or transmission fluid under the vehicle too. These are signs of a blown gasket, and can mean big trouble for your car and will need immediate attention.
The purpose of the head gaskets is to seal the combustion chambers so that there is no loss of high temperature exhaust gases and to block any oil or coolant from leaking into the chambers. The tricky part about this is having a seal that is tight enough to prevent the gases from escaping, but usually once there is a leak, the easiest way to check it is to look for oil in the coolant or coolant in the oil as they will soon start to mix. To do this, make sure you look in your Ford Expedition repair manual for instructions. Usually, when either the oil or the coolant leaks into the other chamber it will often turn to steam. This is what makes up the while cloud that pours out of the vehicle. The head gasket breaking can mean the end of your engine, so it is best to make sure you look into it as soon as you notice a sign.
There are usually only three reasons a gasket would bust. Poor engine design is one of them, and is something that you should talk to the manufacturer about. If they are unwilling to help you, you may be able to contact a lawyer about the malfunction. Improper gasket installation is another possibility and in that case, if you went to a good mechanic to install the gasket he should have it covered by warranty and be willing to install a new one. If your gasket came with the vehicle, you should be able to talk to the dealer, or the manufacturer about the malfunction. The last reason is one you can control, and that is overheating your engine. You can look in your repair manual to find out some of the causes that would overheat your car. If this is your reason, you have no one to blame other than yourself.
Please remember that a Ford Expedition repair manual will be different from a Chevrolet s-10 repair manual. I have a friend who blew out a gasket treating his Ford like a Chevrolet.
