Clean, clean, clean is always the name of the game in anything you do.
Preparation is always the key to a successful job, no matter what it is.
Follow instructions, They are there for a reason.
Use the proper materials. Always go light on the "goop". You are not "fixing" any leaks, you are "preventing" them.
Just a dab of the "proper" type of silicone in the corners. There are many types.
Never over tighten the fastener. There are torque values for every application. These specs are found in your Factory Service Manual.
More problems are caused by overtightening than under.
One more thing. Gaskets only exist because of different materials have different expansion rates and to compensate for minor machining irregularities. If all the parts of an engine were of the same material, machined to the same surface finish and warmed up and cooled down to the exact same temps. You would not need a gasket. An example is the some vehicles with cast iron heads do not come from the factory with a gasket between the head and the exhaust manifold. That is because when new the surfaces are clean, straight, flat and the materials of the cylinder head and the manifold are the same. So expansion and contraction rates are very similar.
Modern cars use aluminum heads, tubular exhaust manifolds and plastic intakes. .
Engines are made of several different materials, eg.. aluminum, steel, cast iron, recently plastics etc... that are attached to each other so the Gasket is the key to a leak free assembly. never use an inferior quality gasket.
This should be your credo on anything that you will spend your money on " The quality is remembered long after the price is forgotten"
Mitch is the man on gaskets. Great info for you guys.
