Pipe Joint Compound
Important: Three types of sealer are commonly used in engines. These are RTV sealer, anaerobic
gasket eliminator sealer, and pipe joint compound. The correct sealer and amount
must be used in the proper location to prevent oil leaks. DO NOT interchange the
three types of sealers. Use only the specific sealer or the equivalent as recommended
in the service procedure.
| • | To remove the sealant or the gasket material, follow all safety recommendations
and directions that are on the container. |
| • | Apply the pipe joint compound to a clean surface. Use a bead size or
quantity as specified in the procedure. Run the bead to the inside of any bolt
holes. Do not allow the sealer to enter any blind threaded holes, as it may prevent
the bolt from clamping properly or cause component damage when the bolt is tightened. |
| • | Apply a continuous bead of pipe joint compound to one sealing surface.
Sealing surfaces to be resealed must be clean and dry. |
| • | Tighten the bolts to specifications. Do not overtighten. |
RTV Sealer
| • | Room Temperature Vulcanizing (RTV) sealant hardens when exposed to air.
This type sealer is used where two non-rigid parts (such as the intake manifold
and the engine block) are assembled together. |
| • | Do not use Room Temperature Vulcanizing (RTV) sealant in areas where
extreme temperatures are expected. These areas include: exhaust manifold, head
gasket, or other surfaces where a gasket eliminator is specified. |
| • | To remove the sealant or the gasket material, follow all safety recommendations
and directions that are on the container. |
| • | Apply RTV to a clean surface. Use a bead size as specified in the procedure.
Run the bead to the inside of any bolt holes. Do not allow the sealer to enter
any blind threaded holes, as it may prevent the bolt from clamping properly or
cause damage when the bolt is tightened. |
| • | Assemble components while RTV is still wet (within 3 minutes).
Do not wait for RTV to skin over. |
| • | Tighten bolts to specifications. Do not overtighten. |
Anaerobic Sealer
| • | Anaerobic gasket eliminator hardens in the absence of air. This type
sealer is used where two rigid parts (such as castings) are assembled together.
When two rigid parts are disassembled and no sealer or gasket is readily noticeable,
the parts were probably assembled using a gasket eliminator. |
| • | To remove the sealant or the gasket material, follow all safety recommendations
and directions that are on the container. |
| • | Apply a continuous bead of gasket eliminator to one flange. Surfaces
to be resealed must be clean and dry. |
| • | Spread the sealer evenly with your finger to get a uniform coating on
the sealing surface. |
| • | Do not allow the sealer to enter any blind threaded holes, as it may
prevent the bolt from clamping properly or cause damage when tightened. |
| | Important: Anaerobic sealed joints that are partially torqued and allowed to cure more
than five minutes may result in incorrect shimming and sealing of the joint.
Do not allow the sealer to enter any blind threaded holes, as it may prevent
the bolt from seating properly or cause damage when the bolt is tightened.
|
| • | Tighten bolts to specifications. Do not overtighten. |
| • | After properly tightening the fasteners, remove the excess sealer from
the outside of the joint. |
