Head Gasket Replacement


head gasket replacementIf you’ve got a leaking head gasket in your vehicle, head gasket replacement and doing any accompanying machine work is the best way to get your motor back in good working condition.  If that isn’t an option for your vehicle financially or otherwise, consider using BlueDevil Head Gasket Sealer to stop your head gasket leak and keep your car on the road!

If you’re ready to tackle a head gasket job yourself, this video will help you step by step in getting this apart and back together!  The process should be similar for most longitudinal “V” style engines with overhead camshafts. If your engine has a pushrod style camshaft or is an “L” style motor it will simplify the process significantly as you won’t have to remove any timing components or in a straight 4 or straight 6 motor you will only have 1 head to remove.

Before you start your head gasket replacement we recommend taking lots of pictures of the motor before you take it apart to help with reassembly.  It’s also important to label electrical connectors, vacuum lines, and any other hoses and fitting. Similarly, it’s important to remember where fasteners came from so it can be helpful to draw maps, put them in labeled baggies or have a large work surface you’re sure won’t be disturbed where you can put them in order and label them.  Now you’re ready to start!!

Head Gasket Replacement:

  1. Drain the coolant from the radiator and engine block
  2. Remove any accessories, brackets, and manifolds attached to the heads
  3. Remove the valve covers and head bolts, then remove the cylinder heads
  4. Measure the block and cylinder head for flatness
  5. Reinstall the cylinder heads with new gaskets
  6. Reinstall accessories, brackets, and manifolds and refill the cooling system.

Measuring the Engine Block and Cylinder Heads for Flatness

In this video, you can see the head gaskets we took out of the motor are intact and not blown but there was still a leak because the cylinder heads warped due to overheating.  Most cylinder heads these days are made from aluminum which can expand significantly at higher temperatures. This can cause the cylinder head to look like a frown (not visibly, but if measured end to end you can find it warped) and where it arches on the middle cylinders it will allow coolant to flow past the gasket into the cylinder.

If your heads or block are warped, a new head gasket won’t stop the leak so make sure to measure both for flatness.  For more information on how to do that, check out this article from Engine Builder’s Magazine.

    Do I need to change my oil which is contaminated with water prior to use

      If you are getting water/coolant into the oil, we recommend changing the oil before and after the BlueDevil procedure. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!
