Which side is up on head gasket?
The edge of the gasket with the “ UP ” stamp must be kept up toward the top of the engine block.
What is gasket where it is used?
Wikipedia: “Fills the space between two objects, generally to prevent leakage between the two objects while under compression. Gaskets save money by allowing less precise mating surface machining and allowing the gasket to accommodate for the flange irregularities….”
Should I use gasket sealer with a gasket?
A general rule, if you are using gasket sealant, you don’t need a lot! Automotive applications commonly use gasket sealant alongside solid gaskets, as they are repairing older parts. Gasket sealant can be used to make cheaper gasket materials more robust, increasing adhesion and chemical/water resistance.
What precautions should be taken when tightening a part fitted with a gasket?
Carefully fit the gasket taking care not to damage the gasket surface….Recommendations:
- Choose as thin a material as possible.
- Clean the flange faces and remove any dirt on the studs / bolts /nuts.
- Lubricate the threads and the nut face. If possible use a lubricant based on:
What is the difference between a gasket and an O ring?
Gaskets are flat pieces of material used to make a seal between two flat surfaces, usually with a bolted joint. O-rings are round, ring-shaped pieces that must set in a groove to create a seal between two parts. While gaskets are most commonly circles, they are also manufactured in a variety of other shapes.
How do I install a new head gasket?

How much does gasket cost?
According to a national average, it costs between $1,624 and $1,979 for a head gasket replacement. The associated labor costs are estimated between $909 and $1147 while the parts themselves vary in the range of $715 and $832.
How does a gasket work?
The compression and subsequent displacement of the material when gasket material is compressed between two surfaces causes a seal to be formed that is maintained with movement, vibration, temperature fluctuations and the presence of chemicals, fluids, oils and steam.
Can a gasket be installed in either direction?
There are no directional markings on the gaskets. Water outlet and thermostat gaskets can be installed with the striping facing either direction, as long as there no directional indicators. If there are bypass holes, the gasket must be installed in the correct orientation to allow coolant flow.
Which is the correct position for the restrictor gasket?
Due to our engineering background at MerCruiser with Marine Exhaust Systems we’re regularly asked about the positioning of the Dry Joint Exhaust System full flow gasket versus the restrictor gasket, along with which directional orientation is correct for the restrcitor hole itself.
What do you need to know about a gasket on a head?
Look at the head surface and the block along with the gasket for the failure areas. The gasket will be a thin piece of sealing material that can be seen once you remove the head. The gasket can be made out of metal, deformable material, or a combination of both.
Which is the correct side to install Fel-Pro gaskets?
When installing Fel-Pro exhaust manifold gaskets, if there is a smooth, metallic side and a composite side, the metallic side should be installed facing out, meaning toward the exhaust manifold.
