FAQ:

Q: How can I tell if head gasket is good?

A: How to Test a Head Gasket to See If the Car Is Still Safe for Driving Fill the coolant up and drive the car around with the coolant cap loose. Let the speed work its way up to about 50 mph. Drive around for an afternoon and see how much coolant the engine consumes during a 50-mile trip.

Q: What is a bad head gasket?

A: But basically a bad head gasket means engine death in two senses. One is that with a bad enough breach the engine will run very poorly or not at all because there is no compression.

Q: Do I have to re-torque my gasket?

A: The best scenario is to re-torque all gaskets after they have seen their first heat cycle. This will provide sufficient loading after the initial relaxation of the part due to heat exposure. Gaskets that NEED to be re-torqued are typically softer construction, with low recovery values and can benefit by being reloaded or re-torqued.

Q: What is the best head gasket sealant to use?

A: BlueDevil holds the reputation for being the best head gasket sealer on the market for 4 or 6 cylinder engines, or at least the most popular brand. The Pour and Go is really designed for the people who are not auto savy and want a very easy do it yourself solution.
