Can I Drive with a Leaking Head Gasket?

driving with a leaking head gasketA leaking head gasket can cause a lot of problems with your car.  The biggest problem caused by a leaking head gasket is the loss of coolant.  Whether the leak is external, causing a water leak into your engine bay, or internal, causing coolant to be pulled into your combustion chamber, losing coolant can lead to a dangerous situation in your vehicle.  A low coolant level can lead to your engine overheating which can quickly cause a lot of damage.

A leaking head gasket can also cause problems with your motor as coolant is drawn into the combustion chamber.  Burning coolant can foul your spark plugs, and pooled coolant when your motor is off will quickly cause rust and corrosion on your cylinder walls and piston rings which can lower your compression and cause long term engine damage.

Driving with a leaking head gasket can also cause further damage to your engine block or head.  If your head gasket is damaged enough to allow a leak, then the leaking water and pressure can erode the metal of your head and engine block at the leak point.  Also, the abnormal temperature gradients around the leak point can cause warping of the block and head.  All of these factors can lead to permanent damage of the metal components in your engine.  If your engine block or cylinder heads are damaged from your head gasket leak, then that will significantly increase the cost of repairs.

Leaking Head GasketIf you catch a leaking head gasket early on and choose to replace the head gaskets, often you can simply replace the head gaskets and reinstall the cylinder head as is.  If a leak is allowed to continue and the head or block gets eroded or warped then you will need to do a significant amount of machine work to repair the block or heads, or replace them.  Replacement and machine work can be an extremely expensive process and double or triple the costs of replacing your head gaskets.

If you are forced to drive with a leaking head gasket the most important thing you can do is keep a close eye on your coolant level and temperature gauge to make sure your engine doesn’t overheat.  If your engine overheats it can quickly make your head gasket leak worse as well as damage other components in your engine.

Luckily, you shouldn’t have to be forced to drive with a leaking head gasket.  Head gasket repair doesn’t have to be an extremely expensive repair and doesn’t have to leave your car in the shop for weeks.  BlueDevil Head Gasket Sealer is an inexpensive and easy to use solution for your vehicle.  BlueDevil Head Gasket Sealer is a non-particulate chemical sealing agent that can bond to cast iron, steel and aluminum so it can seal your head gasket leak no matter what type of engine you have.  Also, it has the ability to seal leaks due to blown head gaskets even if there is erosion or warping present in your head or block near the leak!  Since BlueDevil Head Gasket Sealer is not a particulate sealing agent it won’t clog or harm any other area of your engine and will create a permanent repair at the leak point allowing you to continue driving your vehicle like normal.

  1. Hola este producto me dejo totalmente sorprendido. Mi carro llevaba un mes guardado y yo buscando un mecánico que se metiera a arreglarme lo ,
    Hay que rogarles, para que te cambien las juntas ya que es un trabajo duro y costoso .
    Al ver que nadie me quería hacer ese trabajo empecé a consultar en Internet y encontré esta solución Y la probé.
    Jajaja quede super contento al ver el resultado.
    Lo que no se es si esto será permanente o mejor lo vendo ya que esta bueno ?

  2. Can Blue Devil Head Gasket Sealer be used on a car which had another sealant applied rather unsuccessfuly?
    (My car was overheating, thermostat was replaced, mechanic used sealer. But car was still overheating. I later found out that he did not actually FLUSH the radiator, but just drained out the coolant….so I’m not even sure that he did the procedure correctly.)
    I am looking to have this procedure re-done, but not sure if it can be. Also, not sure how to find a mechanic who will do it correctly!
    This is a high mileage car (over 218, 000 mi.) which I have no money to replace, so am looking for a sort of miracle here!

      If another product was used previously in the system, we recommend flushing the system with BlueDevil Radiator Flush, found here on our website:, to remove any remnants of the product prior to adding BlueDevil . Not knowing the chemical formulation of the other product used, we would not advise mixing the two. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!
